28V Rectifier

Description
Specifications

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

They 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.
