Specications
The Model 202
is a 3-phase, auto-ranging, dual-range voltage
monitor that protects 190-480VAC, 50*/60Hz
motors regardless of size. The product provides
a user selectable nominal voltage setpoint and the
voltage monitor automatically selects between the
200V and 400V range.
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 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 202 includes advanced single
LED diagnostics. Five different light patterns
distinguish between faults and normal conditions.
The Model 202-RP
monitors the phase rotation of 3-phase systems and
trips on reverse phase only. Critical applications
include fan motors, scroll compressors, grinders,
conveyor systems, elevators and escalators. The
status light turns green and the relay is activated
when rotation is correct.
