| Voltage Monitor - VMR-3P |
| Protection of 3 Phase devices against Over voltage, Under voltage, Single Phasing, Reverse Phasing & Unbalance Supply are one of the major issues in electrical systems. For safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to Unbalance Supply, Single Phasing & Reverse Phasing conditions. VMR-3P detects such Conditions & protect the load from burn out. 'PROTON's VMR-3P offer above protections along with 3 digit display showing
R-Y,Y-B,B-R voltages in scanning mode with precise accuracy. LOW/HIGH voltage tripping to ensure trouble free running of 3-phase Loads.
Features:
- Voltage protection along with digital voltage readout
- Wide range of supply variation
- Unit will also work if any one phase is present
- Protection against Under voltage
- Indications for Low voltage, High Voltage, SPP & Relay ON
- Message Display for SPP, Reverse Phasing & Unbalance Faults
- Protection against Over voltage
- Phase unbalance protection
- Trip Delay for Under voltage & Unbalance is settable
- Reverse Phasing Protection can be able to bypass through settings
- Single Phasing & Reverse Phasing protection
- No separate auxiliary supply required
