- Advanced LED diagnostics quick visual indicator for cause of trip, LED indications include, normal operation, power-up restart delay, reverse phase trip, unbalance/ 1-phase trip, high/low voltage trip
- Includes high voltage detection
- High/low voltage fault 4 s, unbalance and phasing faults 2 s
The 201A is a 3-phase, auto-ranging, dual range voltage monitor that protects 190 to 480 VAC, 50/60 Hz motors regardless of size. The product provides a user selectable nominal voltage set point and the voltage monitor automatically selects between the 200 VAC and 400 VAC range. The 201A includes advanced single LED diagnostics, where color and light patterns distinguish between faults and normal conditions. This unique microcontroller based voltage and phase sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the 201A's 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.
