3-Phase Monitor
The Model 265 3-Phase Monitor provides essential protection for industrial equipment. It continuously monitors for phase loss, low voltage, and phase reversal, safeguarding critical systems from potential damage. Featuring an automatic reset type and an adjustable reset time from 20 to 300 seconds, it ensures operational continuity following fault conditions. The unit operates reliably across a nominal AC voltage of 208/240VAC, with an adjustment range of 160-240V, accommodating various power supply conditions. Its robust design, featuring a 50ms maximum response time and SPDT 10 amp output contacts, contributes to system stability and control. With a power consumption of 0.5W and an operating temperature range of -20° to +131° F, this monitor is engineered for consistent performance in demanding environments, offering dependable protection for three-phase applications.
