201A

201A is a three-phase, auto-ranging, dual-range voltage monitor that protects motors regardless of their size. 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. Typical applications include fan motors, air conditioners, compressors, heat, well and sump pumps, small conveyor motors.
