| 201A Series - 3-Phase Voltage/Phase Monitor |
| Series Description: The 201A series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190–480 V ac, 50*/60 Hz motors regardless of their size. This monitor provides a user-selectable nominal voltage setpoint and will automatically select between the 200 V and 400 V range. It includes advanced, single LED diagnostics where color and light patterns distinguish between faults and normal conditions. This unique microcontroller-based voltage and phase-sensing unit constantly monitors the three-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels for a specified restart delay time. |
| Series Applications: Fan motors, Air conditioners, Compressors, Heat, well, and sump pumps, Small conveyer motors |
- Proprietary microcontroller-based circuitry: Constant monitoring of single-phase, low-voltage, voltage unbalance, phase reversal, power line conditions – high-voltage monitoring is optional
- Auto-sensing wide voltage range: Automatically senses system voltage between 190–480 V ac. Saves setup time
- Advanced LED diagnostics: LED indications include: normal operation, power-up restart delay, reverse-phase trip, unbalance/single-phase trip, high/low voltage trip
- Compact design for 8-pin; DIN-rail or surface mount: Allows flexibility in panel installation
