| Series Features |
| 102A Series Three-Phase Voltage/Phase Monitor Series |
| Series Description: The 102A series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190600 V ac, 50*/60 Hz motors regardless of size. This monitor provides a user-selectable nominal voltage setpoint and will automatically select between the 200 V and 400 V range. A unique microcontroller-based voltage and phase-sensing circuit 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. The 102A monitor includes advanced, single LED diagnostics with five different light patterns that distinguish between faults and normal conditions. LED indications include normal operation, power-up restart delay, reverse-phase trip, unbalance/single-phase trip, and high- or low-voltage trip. |
| Series Applications: Fan motors, Air conditioners, Compressors, Heat, well, and sump pumps, Small conveyer motors |
