Phase Under Voltage plus Time Delay
- Designed to withstand overloads up to 125% (cont.), 150% (10s)
- Microprocessor based
- True R.M.S. monitoring
- Selectable nominal voltages (220, 230, 240, 254, 265, 277V (L>N))
- Monitors own supply and detects an Under voltage condition on one or more phases
- Adjustment for Differential and Under voltage trip level
- Adjustment for Time delay
- DPDT relay output 8A
- Green LED indication for supply status
