This GPU model – rated at 2800 peak starting amps – can be used on the ramp to conduct engine starting and will provide 28.5V of continuous, clean, no duty cycle power up to 50 Amps DC when plugged into AC wall power. Please specify AC voltage when you are placing your order.

With its high battery capacity (56Ah) and its integrated 50-Amp power supply, this full 24V mobile START PAC® is ideal for starting multiple aircraft and powering up the cockpit for training, maintenance or software downloads. It can be used in remote locations using battery power alone and give extended time for cockpit maintenance checkout. Its large battery capacity will allow extended usage time when no AC power source is available.

Able to perform multiple turbine or piston engine starts, this START PAC® unit will allow your turbine engines to experience faster and cooler engine starts than with most ship’s aircraft batteries (the turbine is spooled to more revolutions per second before fuel is injected). Thus, turbine life will be extended because there is less stress on the starter and other engine components. This will preserve the aircraft’s costly batteries and help lower operating costs. When using your START PAC’s integrated power supply, you save the on-board battery for emergency use only. As a START PAC® secures all your engine starts, this unit will ensure that you have no downtime.

The environmentally responsible, low VOC powder coating protects the case from wear, tear and poor weather conditions. Additionally, an all-weather cover accessory is also available as an option for this unit in order to protect it further from inclement weather to gain the maximum performance and product life.
