3-Phase Voltage Monitor
Model 460L
The Model 460L is designed to protect 3-phase loads from damaging power conditions. The 460L’s wide operating range combined
with UL and CE compliance enables quick access to domestic and
global markets.
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 4 second trip delay. The output relay reactivates after line power conditions return
to an acceptable level for a specied amount of time (Restart Delay). The trip and restart delays prevent nuisance tripping due to
rapidly uctuating line power conditions.
The Model 460L automatically senses whether it is connected to a
190-240VAC 60Hz system, a 440-480VAC 60Hz system or a 380416VAC 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240VAC or 380-480VAC. Other adjustments include a 1-500 second restart delay.
