C200-480V
The Model 200 3-Phase Voltage Unbalance Monitor, SKU C200, offers essential protection for industrial three-phase systems. Voltage unbalance can lead to motor overheating and premature equipment failure. This monitor detects deviations from nominal 480VAC, ensuring system integrity. With a rapid 100ms response time and a precise ±0.1% repeat accuracy, it provides reliable fault detection. Users can adjust unbalance thresholds from 2% to 10% to suit specific application requirements. Its DPDT 10 amp contacts facilitate direct control of protective devices. The unit operates effectively across a -20° to +131° F temperature range, supporting continuous operation in diverse industrial environments. This device helps maintain system health and extends equipment lifespan.
The Model 200 3-Phase Voltage Unbalance Monitor is designed to
continuously monitor a three-phase line for unbalanced voltage
conditions. This device will only energize the relay if an unbalance
exists. Zero volts on all three phases is considered a balanced
condition. This allows the Model 200 to be used with shunt breakers, so
that the breaker can shut off the main power without tripping the
monitor. The solid-state sensing circuit drives an internal
electromechanical relay. Indicator lights on the monitor show when the
voltage balance is within an acceptable range; when an unbalance exists;
and when the relay is actually tripped. When an acceptable voltage
balance is reapplied, the Model 200 will automatically reset the relay.
