GPU1700 Twin - Starter unit - 24 V DC

Designed for service in the field, our 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 1700 Twin uses two GPU 1700 units connected in parallel by a plug-in polarized heavy-duty cable to double the battery capacity from 32 Ah to 64 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 1700 Twin can be split into separate modules for ease of transport. In regular use for emergency power and turbine starting, the GPU 1700 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 and large free turbines.

Each GPU 1700 is fitted with solid state voltmeter to monitor battery voltage and is supplied with a heavy-duty canvas protective jacket.
