The Phase Guard is a phase-voltage-balance monitoring device designed for use
with magnetic controls to automatically prevent three phase motors or other equipment
from operating or attempting to start up under open phase or single-phase conditions,
thereby eliminating burnouts and consequent down-time frequently incurred by phase
A Phase Guard will:
- Extend the life of the motor.
- Reduce downtime related to motor issues.
- Minimize the need for expensive repairs or equipment replacement.
Protection Against: Phase Loss, Phase Unbalance,
Reverse Phase, Overvoltage,
and Low Voltage (undervoltage) faults.
Logging of faults that occur for review at a later.
Digital readout display provides information about the current condition and
ability to browse past events.
Desktop Admin software to fully configure and customize the Phase Guard for
your particular needs.
Ability to add new features to any Phase Guard after it's been purchased from
the factory. Save time and money by having units on hand and ready to be deployed
with the settings and features of your choice.
