Model 200 3-Phase Voltage Unbalance Monitor
The Model 200 3-Phase Voltage Unbalance Monitor, SKU B200A, provides essential protection for industrial equipment. Voltage unbalance can lead to motor overheating, reduced efficiency, and premature failure. This monitor precisely detects unbalance conditions, offering an adjustable range from 2% to 10%. Its rapid 100ms response time ensures quick detection, while the adjustable dropout time, from 0.2 to 20 seconds, allows for tailored system integration. With a robust DPDT 10 amp contact rating at 240VAC resistive, it reliably controls protective devices. The unit operates effectively across a wide temperature range of -20 to +131 F, ensuring consistent performance in diverse industrial environments. Its automatic reset type simplifies operation, minimizing downtime and maintenance requirements. This device contributes to extending equipment lifespan and maintaining operational continuity.
