SymCom Model 102A is an auto-ranging voltage monitor designed to protect 3-phase motors regardless of size. It is used on 190-480VAC, 50 or 60Hz motors to prevent damage caused by incoming power problems. A unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels. The Model 102A includes advanced single LED diagnostics. Five different light patterns distinguish between faults and normal conditions.

The Model 102-600 is a voltage monitor designed to protect 3-phase, 475-600VAC, 50/60Hz motors from damage caused by low voltage, voltage unbalance, single phasing, and phase reversal. A unique microcontroller-based voltage sensing circuit constantly monitors the single-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the102-600's output relay is deactivated after a fixed trip delay. The output relay reactivates after power line conditions return to an acceptable level and a fixed amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.
