Two heavy duty 24V DC stainless steel aircraft start units connected in parallel to double the turbine starting capacity. Designed for use in harsh or saline environments and fitted with solid state voltmeter and robust push/pull isolator.
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.
Designed for service in the field, Powervamp's heavy-duty stainless steel cased twin packs are recognized by relief agencies operating in extreme environments as the best portable aircraft start unit for DC aircraft and helicopters requiring a 24V DC or external 24/48V DC parallel/series start, these twin units are in use worldwide.
The GPU 2400 Twin uses two GPU 2400 units connected in parallel by a plug-in polarized heavy-duty cable to double the battery capacity from 43 Ah to 86 Ah for increased starting capability. Using an optional second Nato lead set, the units can be deployed individually or used where an aircraft requires a parallel start.
Each unit includes a heavy-duty push/pull isolator switch with replaceable copper contacts ensuring maximum power transfer with minimum voltage drop. The lockable ‘R’ clip ensures the aircraft start unit is cleared for air transportation. The GPU 2400 Twin can be split into separate modules for ease of transport. In regular use for emergency power and turbine starting, the GPU 2400 is ideal for providing the first start of the day.
Fitted with dual 12V DC automatic 3-stage internal chargers for maximum cell longevity, these aircraft start units will start all APUs, large corporate jets and commuter aircraft with shaft turbines. The GPU 1700 is fitted with a solid state voltmeter to monitor battery voltage and is also supplied with a heavy-duty canvas protective jacket.
Also available are the Powervamp GPU Fast Chargers, designed to re–charge the GPU 1700, GPU 1700 Twin, GPU 2400 and GPU 2400 Twin units quickly and safely whilst also optimising the batteries for maximum longevity. Click here to view the datasheet.
