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. GPU 1500/40 TWIN The modular design allows easy swap out and field servicing and also allows two GPUs to be paralleled together, creating the GPU 1500/40 Twin. The Twin is suitable for starting larger helicopters and business jets where larger turbines or turboprop aircraft require higher instant amperage and longer start cycles. It will deliver 80A continuous output when connected to AC power and is ideal for lengthy pre-fight checks. The units are fitted with solid state voltmeter with ‘push to view’ button to monitor battery voltage. A spring-loaded output cover ensures each unit is cleared for air transportation. They are supplied with Nato plug lead set, input lead and heavy-duty padded jacket.
