SNP-1 / СНП-1 Power Fail Relay (Gyro Horizon Supply Monitoring)

SNP-1 (СНП-1) is a power fail relay used on Mi-8, Mi-17 and Mi-171 helicopters to monitor the electrical supply of gyro horizons. The relay generates a failure signal when AC supply phases 36 V 400 Hz are lost or out of limits, or when DC 27 V power is interrupted or drops below permissible values. Offered as a standalone certified aviation electrical unit for sale with traceability and documentation available subject to contract.
