It’s essential that the unit you select for starting turbines and for providing sufficient power for pre-flight checks, also provides the performance and product lifespan that you need. The following checklist has been specifically designed to assist Powervamp customers with their aircraft start unit selection. And of course, Powervamp’s technical support department or appointed distributors will also be pleased to offer advice in helping you select the correct GPU. Is the pack for emergency use only? A GPU with minimum capacity may be sufficient, as it is unlikely to encounter intense usage. ✓ Recommended: Powervamp GPU 1700 Will the pack be carried on board? You’ll need to consider the weight of the unit, but beware of reducing weight at the cost of performance. ✓ Recommended: Coolspool 17 Will the GPU be used for programming/pre-flight checks before spool-up? Allow additional amp/hr capacity to ensure a cool start. ✓ Recommended: GPU 2400 Will the GPU be used as the main ramp/hangar GPU on multiple operations? It’s best to extend the GPU life with extra amp/hr capacity. ✓ Recommended: Coolspool 130 or 260 ramp cart depending on aircraft size (for extended battery life) Is the GPU required for regular compressor washing? The battery will need more frequent replacement if using an undersize pack. ✓ Recommended: Coolspool 260 13 SELECTING THE CORRECT AIRCRAFT START UNIT Will the GPU be used for regular avionics or maintenance work? High discharge batteries designed for starting are not designed for continuous powering. Consider a GPU with an internal power supply or run our separate DC power supply in parallel with the pack. ✓ Recommended: Coolspool cart range or GPU1500/40 or standard battery pack in parallel with one of our power supplies Does the aircraft have tight upper avionic limits that must not exceed 29–30 volts? ✓ Recommended: Coolspool 130, 260 or 410 with batteries configured to a nominal voltage of 26V DC instead of 28V DC Is the requirement for line ops on regional/ commuter aircraft-typically ATR and Q400 aircraft? In this case, there must be sufficient capacity to deliver continuous ground power for 30-40 minutes and to start a heavy turbine. ✓ Recommended: Coolspool 410 (designed for this application) Is continuous DC power required for maintenance or training? Select a DC power supply. Ensure input circuit breaker is rated to handle the maximum required DC output. ✓ Recommended: PS50, PS100 or S300 How many engine starts are required before the GPU can be re-charged? Remember: starts, pre-flights and line ops require amp/hr capacity to maintain volts. More starts require more amp/hr capacity and more weight, and therefore a larger size DC battery cart. ✓ Recommended: Coolspool 410 Is engine free turbine or shaft turbine/turboprop or turbofan? Longer spool-up times of shaft turbines will require more amp/hr capacity. ✓ Recommended: GPU1400/40 NOTE Selecting any portable GPU is not an exact science. It is a compromise between weight, size, necessary performance, recharge time, battery life and price. It should be noted that the life of the GPU is affected by the depth of discharge each time the GPU is used. The deeper the discharge each time, the sooner the batteries will need replacing. It is preferable and more cost effective to buy a GPU with maximum amp/hr capacity. Selecting the correct unit 28V DC Ramp Carts Coolspool 410: powering an ATR-72/600 15 28V DC RAMP CARTS The award-winning Coolspool range of 28V DC battery carts are a cost saving, environmentally-friendly alternative to diesel GPUs. Where no AC power is present or noise curfews prohibit use of diesel GPUs, they are a highly efficient, low cost power source – operating at a fraction of the cost of a diesel GPU, yet able to deliver the same power and turbine starting output. These large, new generation, powerful, heavy-duty battery carts provide a combination of instant high amperage with pure DC wave form and full mobility, low initial investment and extremely low operating costs. Their zero noise and zero carbon footprint are important environmental considerations. With the price of diesel increasing and stricter legislation on noise and CO2 emissions, the advanced technology Coolspool battery cart range is the way forward for regional and feeder airlines’ FBOs and ground handling agents under pressure to reduce direct operating costs. Powervamp’s large 28 volt Coolspool battery cart GPUs are increasingly being used to provide the smooth 28 volt DC power required for pre-flight checks, avionics programming or maintenance. They are ideal for crew training, aircraft turnround/cabin cleaning at remote airport stands (where power can be required for anything from a few minutes to several hours) or where noise curfews or the lack of any electrical supply prohibit any other method of powering the aircraft’s DC systems.

Remaining ahead of the curve with the faster speeds of the VLJs requires private and corporate pilots to be proficient in the use of their EFIS. Practice and the need to update software are two reasons why all aircraft operators should own a reliable and compact power supply, able to be used for training, fault finding or software updates. Powervamp’s first 28 volt 40 amp power supply was produced in 1995 as a solution to the problem of training police observers on FLIR systems. Until then, training involved expensive helicopter flying hours or powering a FLIR system with battery GPUs with limited power duration. 0 100 200 300 400 500 600 0 10 20 30 40 50 60 DC amps output Output current at 28.3V DC (A) a a a a PS300 PS300 PS100 PS100 200V 3-phase mains voltage 200V 3-phase mains voltage 230V 1-phase mains voltage 230V 1-phase mains voltage 115V 1-phase mains voltage 115V 1-phase mains voltage 400V 3-phase mains voltage 200V 3-phase mains voltage 230V 1-phase mains voltage 115V 1-phase mains voltage AC power input Input current per phase (A) Mains power input required to deliver maximum output for the PS100 and PS300 power supply Power supplies Power Supply Output voltage (V) Maximum current (A) Input voltage required (V) PS30M 28 30 110/230 1-ph PS50M 28 50 110/230 1-ph PS100 28 100 110/230 1-ph PS300 28 300 230/400 3-ph 30 TO 300 AMP POWER SUPPLIES: COMPACT – RELIABLE – ESSENTIAL Powervamp, with its range of power supplies from 30 to 300 amps, manufactures units for all types of aircraft from the Cessna 175 to the largest of DC aircraft such as the ATR, Embraer 145, Q400 and Saab 340. Confirmation of Powervamp’s quality and performance has been endorsed by some of the world’s largest manufacturers of private, business and corporate jets who have selected Powervamp power supplies as their branded product supplied to customers for software updates and a source of DC power at remote locations. Other manufacturers too have selected Powervamp power supplies as the chosen unit for their service support teams. In every case, quality, reliability and product support are key. 34 DC POWER SUPPLIES SELECTING THE CORRECT POWER SUPPLY i When deciding on the size of power supply, operators should consider the following: Aircraft load fluctuation If aircraft loads are likely to fluctuate, Powervamp strongly recommends a power supply with a digital voltmeter. Power demand fluctuating close to or above overload will trigger a progressive automatic voltage shutdown which can cause radio static and possible data loss. A digital voltmeter will visually alert the operator to the situation. All Powervamp power supplies are fitted with accurate digital voltmeters. The larger units are fitted with digital ammeters to give pilots and engineers an instant reading of the load as each system is powered up. Output limitations Operators should be aware of possible power output limitations at 110 volts where the mains circuit breaker rating may be insufficient to allow maximum DC output. In this situation, the anticipated output load will need to be checked against the input amperage, which must be less than the circuit breaker rating.

It is designed to be easily transported by aircraft, helicopter or vehicle. Able to be carried by one man, it uses a powerful 24–28 volt DC motor direct coupled to a high-speed pump with phosphor bronze sliding vanes. The power source can be any 24/28 volt supply such as a portable GPU, vehicle battery or aircraft DC bus. Alternatively a 110/220 volt AC supply can be used with a DC voltage converter. Fuel drums or containers that would otherwise require a settling period after transport to allow fuel/water separation can be pumped immediately. Fuel drained from aircraft, that would otherwise have been discarded, can safely be re-used once passed though the Portapump. An inlet non-return valve prevents drainback (siphoning) and maintains the back pressure to allow activation of the pressure- operated switch that shuts off the pump motor. Normal pumping is indicated by a reading of approximately 5 PSI on the gauge. Progressive filter blocking is indicated by a gradual rise in differential pressure.

REPAIRS AND MAINTENANCE Product support is the core capability of the servicing operation. Skilled engineers can handle repairs and maintenance across the entire range. Products can be returned to the service centre or dealt with on site, as UK-wide travel is part of the company’s service proposition. An increasing number of Powervamp customers take out an ongoing maintenance contract which can cover work on competitors’ equipment, as well as Powervamp’s own product lines. Activities range from routine battery checks and discharge monitoring to complete swap-outs of faulty materials and components. To ensure that its service engineers have all the skills needed for any eventuality, Powervamp runs a comprehensive induction and training programme. New recruits are required to spend time on Powervamp’s assembly line in order to gain knowledge of product assembly. Staff are also trained extensively in servicing, and repairing, prior to working in the field. SITE SURVEYS Powervamp also offers a detailed site surveying service which includes assessing a site’s power requirements in order to recommend an appropriate fixed electrical ground power unit. Powervamp is regularly approached to calculate the costs when companies wish to embark on an energy saving scheme, providing more power-efficient equipment COMMISSIONING Commissioning is another key function for the servicing team. Ground power unit operators such as major airports sometimes arrange their own installation, but Powervamp engineers still play a vital role, checking that the work has been done correctly – verifying that electrical loads are within stated tolerance or that the installation environment is appropriate. The process can also include the safe disposal of life-expired components with full compliance certification. TURNKEY INSTALLATION The team can also offer a complete turnkey installation and commissioning package, either using its own staff or calling on approved specialist contractors with experience and training in Powervamp products.

The company is ISO 9001:2002 accredited. In the early 1990s, Powervamp pioneered the concept of using remote generator power at airshows to operate its unique 28V DC electrical transformer rectifier units (TRUs) within the static display area. This removed the problems of ground power units, noise and exhaust pollution, and proved a breakthrough for aircraft exhibitors. The concept swiftly developed into the present practice of using all- electric power for 115V AC 400Hz and DC powered aircraft at static displays. PROJECT MANAGEMENT Powervamp’s comprehensive airshow support services range from the supply of 28V DC and 115V 400Hz ground power and air coolers to full project management of the static area, including aircraft positioning, cleaning and many other specialist services. 28V DC AND 115V AC GPUs Powervamp owns most of its equipment, which it renews on a frequent basis. This includes a dedicated stock of its own modern, silent, solid-state 28V DC power supplies, offering from 25 to 400 amps continuous power, and a large number of 115V AC 45–120 kVA frequency converters. Airshow Services AIRSHOW SERVICES STATIC AREA CABLING Exhibitors also benefit from Powervamp’s own extensive supply of cabling and switch gear (approximately 10 tonnes). All equipment is compatible with one type of 3-phase input voltage for simplicity and ease of operation. Because cabling and switch gear is usually pre-matched at the factory before despatch, hook-up time is saved and clients receive power to their aircraft sooner. Powervamp can ship this directly from stock to ensure equipment arrives at the exhibition without the need to source ancillary items locally. AIR CONDITIONING AND SPOT COOLING Powervamp is highly unusual in owning its own large fleet of air-conditioning units. This allows the company the option to ship by sea freight without the client having to absorb part of the extended rental period of a sea journey or the added premium of airfreight as charged by some organisations, thereby reducing costs to the client. At major air shows (and other large events) where all or part of Powervamp’s spot cooler fleet is already under contract, the company has a reciprocal loan agreement with a major spot cooler supplier thereby ensuring that it always has at its disposal sufficient 1, 3 and 5 tonne units to satisfy its requirements. CORRECT POWER CALCULATIONS Knowing the correct kVA static area requirement is critical. Powervamp will calculate your total power needs and can complete any organiser power requirement forms on your behalf. Accurate calculations will minimise your expenditure while ensuring that the risk of a major problem on show opening day caused by under-specifying the power and the tripping of circuit breakers is eliminated. Back-up equipment is always shipped to the venue and is held on site for immediate ‘swap-out’ in case a failure occurs. However, because Powervamp designs, manufactures, owns and operates most of its equipment, its on-site team is usually able to quickly diagnose and fix the problem in less time than it takes to deliver and connect a replacement unit.
