Product Information

Product Information

Size and weight are important considerations for hand-portable aircraft start units. Situations exist where additional battery capacity and performance is required while retaining the essential benefits of mobility or ‘hand-portability’.

The solution, pioneered by Powervamp more than 20 years ago and now adopted throughout the industry, is to connect two units in parallel to create the GPU 1500/40 Twin. The GPU 1500/40 Twin will deliver 80A continuous output when connected to mains power making this unit ideal for maintenance and lengthy pre-flight checks.

The GPU 1500/40 Twin can be split into separate modules for ease of transport and is designed to be carried on board for emergency power or turbine starting. This aircraft start unit is suitable for starting larger helicopters and business jets where larger turbines or turboprop aircraft require higher instant amperage and longer start cycles.

Each GPU is supplied with a power supply LED output monitor for load monitoring and diagnostics, and can be re-charged via its accessory port by any 24–28V DC aircraft power source, including the aircraft 28V DC bus connector.

Each GPU 1500/40 is fitted with solid state voltmeter with ‘push to view’ button to monitor battery voltage. A spring-loaded output cover ensures the aircraft start unit is cleared for air transportation. Supplied with Nato lead set, input leads and heavy-duty canvas protective jackets.
