EACR series combined GPUs

EACR series combined GPUs

Combined power supply units of ЕАСR series are intended to supply power to onboard electrical equipment of aircrafts and helicopters during pre-flight preparation at airports, shop floors of aircraft industry enterprises and complex training simulators in aviation study-training centers. These power supply units have two types of outputs: one with direct current of 28.5V, and second one with alternating current of 400 Hz. DC outputs can be operated both as two-channel with function 24/48 VDC and single-channel with 28.5 VDC.

Two outputs with 3х115/200V 400Hz of total power up to 360 kVA and additionally 3rd output with 400 Hz 36 V of power up to 10 кW can be designed in a power supply unit.

You can use AC and DC outputs simultaneously, so you can use one GPU for supply of several aircrafts. This is contrary to our competitors rule – one GPU for one aircraft.

Anti-condensation unit built into the GPU’s enclosure.
