Mid-Power E-Relay

3-IN-1 product:

Managed by versatile supervision logic and multiple GND/OPN and analog feedback signals. Rugged enough to be used as stand-alone in the aircraft or to be integrated into Power Distribution Units or Panels. The compact design allows close stacking to reduce volume. The same P/N can be con_gured to be used as Electronic relay, Electronic circuit breaker or RCCB. Current can flow in both directions (from A1 to A2 and vice-versa).
