ADVR-054 Universal 5 Amp AVR for shunt and auxiliary windings generators

ADVR-054-400HZ

Intermediate Frequency 400Hz Self Excited 5 Amp Digital Automatic Voltage Regulator for Military spec and Aviation generator

ADVR-054-400HZ is a 5 Amp self excited 400Hz Generator Automatic Voltage Regulator designed to replace most military and aviation 400Hz generator. It has large heat sink which significantly increases cooling efficiency. This AVR has over excitation protection and it can automatically shut-off output when voltage sensing is lost.

Declaration of RoHS Compliance
