Dual-channel

Dual-channel rectifiers can be equipped with KPA series switchgear providing voltage switching during engine start.

New Generation EAR series rectifiers are designed to power on-board electrical equipment and launch aircraft and helicopters with a voltage of 28.5 V and a rated current of up to 1200 A continuously (on request they can be manufactured with great source output parameters), with an overload of up to 2500 A.

New Generation rectifiers are equipped with a MPCU microprocessor control plate, which is intended for control functions, protection and diagnosis. Rectifiers can also be equipped with an access system and energy consumption monitoring system.

In order to attain the parameters required by the new generation of aircraft, we can also propose a complete solution for replacing old versions of TRUs for 400 Hz diesel engine driven GPUs with our converter rectifier units.

A new lightweight compact design of the unit is now available.
