BRN120T5A-3 ser. / БРН120Т5А-3 сер. Voltage Regulation Unit

BRN120T5A-3 (БРН120Т5А-3 сер.) is a voltage regulation unit designed to maintain the specified output voltage of constant-frequency three-phase brushless generators with built-in three-phase exciters and accessible neutrals on Mi-8, Mi-17 and Mi-171 helicopters. The unit also provides reactive current balancing during parallel generator operation in the aircraft electrical power system. It operates from both DC and three-phase AC supplies and ensures stable regulation without false shutdowns during temporary DC voltage drops. Offered as a standalone certified aviation electrical unit for sale with traceability and documentation available subject to contract.
