Time Mark C265 Three-Phase Power Monitoring Unit

Description:

The Time Mark C265 3-Phase Power Monitor is designed to continuously monitor 480 VAC three-phase Wye or Delta power systems for phase loss, low voltage, and phase reversal to protect motors and compressors from damaging electrical conditions. Commonly installed in HVAC equipment, air compressors, motor control centers, pumps, conveyors, and industrial machinery where reliable three-phase power monitoring is essential. Maintenance teams, OEMs, and system integrators use the Time Mark C265 for replacement, retrofit, and preventive maintenance to improve equipment reliability and minimize unplanned downtime.

Applications:

The Time Mark C265 is a solid-state three-phase power monitor designed for HVAC and compressor applications requiring dependable protection against phase loss, low voltage, and phase reversal. Its adjustable restart delay helps prevent short cycling by allowing compressor head pressure to equalize after power interruptions, making it ideal for industrial automation systems, refrigeration equipment, chillers, pumps, compressors, conveyors, and other three-phase motor-driven equipment.
