Model 200 3-Phase Voltage Unbalance Monitor
The Model 200 3-Phase Voltage Unbalance Monitor provides essential protection for industrial equipment. Maintaining balanced voltage is critical for motor longevity and system efficiency. This device accurately monitors 575VAC systems, offering an unbalance adjustment from 2% to 10%. Its rapid 100ms response time ensures prompt detection of voltage irregularities, minimizing potential damage. With a DPDT 10 amp contact rating at 240VAC resistive, it reliably controls external circuits, facilitating timely corrective actions. The monitor's robust design allows operation across a -20° to +131° F temperature range, ensuring consistent performance in diverse industrial environments. Its automatic reset type and adjustable dropout time from 0.2 to 20 seconds offer operational flexibility. This unit helps prevent costly downtime, extends the operational life of connected machinery, and contributes to overall system reliability.
