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 190–600 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
Proprietary microcontroller-based circuitry : Constant monitoring of single-phase, low-voltage, high-voltage (102A-9), voltage unbalance, phase reversal, harmful power line conditions
Auto-sensing wide voltage range: Automatically senses system voltage between 190–480 V ac. Saves setup time
Advanced LED diagnostics: Quick visual indicator for cause of trip
Adjustable trip delay (102A2): Prevents nuisance tripping due to rapidly fluctuating power line conditions
