45UFR
- Under frequency monitoring
- Monitors own supply
- Adjustable Trip level
- Adjustable Hysteresis
- DPDT Relay output
- 45mm wide, DIN Rail mount
When power is applied, the output relay will energise if the monitored frequency is above the set trip level. When the frequency decreases below the set trip level the relay will de-energise. The frequency must then increase above the trip level and plus the set hysteresis setting before it will energise again.
