Model 200 3-Phase Voltage Unbalance Monitor
The Model 200 3-Phase Voltage Unbalance Monitor provides essential protection for industrial systems. This device continuously monitors three-phase AC lines, detecting voltage imbalances that can lead to equipment damage or operational inefficiencies. Its adjustable unbalance threshold, ranging from 2% to 10%, allows for precise application tailoring. A rapid 100ms response time ensures prompt detection of anomalies, minimizing potential downtime. The integrated DPDT 10 amp contacts facilitate direct control of protective circuits, rated for 100,000 electrical operations at load. With a robust design, including transient protection up to 2500VRMS for 10ms and an operating temperature range of -20° to +131° F, the Model 200 maintains system integrity in demanding environments. Its automatic reset function further streamlines operational continuity, reducing manual intervention. The unit's compact dimensions and surface mounting simplify installation within existing control panels.
