Specications
The Model 201A-AU
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. The Model 201A-AU
includes advanced single LED diagnostics, where
five different light patterns distinguish between
faults and normal conditions. Adjustment knobs
allow the user to set a 1-30 second trip delay, a
manual restart or 1-500 second restart delay and a
2-8% voltage unbalance trip point.
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.
