Single-Phase
Voltage Monitor

Engineered
Protection
•
Microcontroller
Based
Universal range from
95-120 or 190-240VAC,
50/60 Hz provides the
versatility needed to
handle global applications.
Two adjustment pots
provide versatility for all
kinds of applications.
Diagnostic LEDs indicate
trip status and provide
simple troubleshooting.
Microcontroller-based
circuitry provides better
accuracy and higher
reliability than analog
designs.
Transient protection meets
IEEE and IEC standards
to allow operation under
tough conditions.
The Model 460-XXX-SP protects single-phase motors from damage caused by
low and high voltage and rapid cycling.Controls are provided to set the nominal
voltage (190-240VAC) and the desired restart delay time (1-500 sec.).
A unique microcontroller-based, voltage-sensing circuit constantly monitors
the voltage 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
an acceptable level for a specified amount of time (restart delay). The restart
delay is also a power-up delay and can be utilized to stagger-start motors on
the same system. The trip delay prevents nuisance tripping due to rapidly
fluctuating power line conditions.
Protects Single-Phase
Motors From:
• Low voltage
• High voltage
