Over & Under 3-Phase Monitor
The MODEL 269R Over & Under 3-Phase Monitor, SKU B269R, offers essential protection for industrial applications. This device monitors high voltage, low voltage, phase loss, and phase reversal conditions, ensuring operational integrity. With a nominal AC voltage of 208/240VAC and 60Hz frequency, it provides precise monitoring capabilities. The adjustable upper range of 210-280V and lower range of 170-240V allow for tailored system integration. Its robust design includes transient protection up to 2500VRMS for 10ms and a repeat accuracy of ±0.1% of the set point. The unit features automatic reset with an adjustable reset time from 0.3 to 5 minutes, minimizing downtime. Output contacts are SPDT 10A at 240VAC resistive, supporting reliable control. The operating temperature range of -20° to +130° F ensures performance in diverse environments.
