• EX2644

    3-Phase Monitor

    The Model 2644 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions.

    The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures.

    Voltage adjustment ranges are sufficiently wide to allow for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. Automatic and manual reset versions are available. The Model 2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor.

  • EX265

    3-Phase Monitor

    The Model 265 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for phase loss, low voltage and phase reversal. When properly adjusted, the Model 265 Monitor will detect phase loss on a loaded motor even when regenerated voltage is present.

    The solid-state sensing circuit drives an internal relay, in a fail-safe configuration, i. e. , the relay is energized when correct voltage and phase rotation are applied.

    Operating power for the Model 265 is drawn from the 3-phase lines being monitored. An adjustable timer delays restarting of the load, allowing up to five minutes for compressor head pressures to bleed off, in the event of short-term power failures.

    The Model 265 Monitor is not sensitive to line current, and can be used with any size motor or compressor. Automatic and manual reset versions are available.

  • EX2652

    3-Phase Monitor

    The Model 2652 3-Phase Monitor is designed to protect motors, pumps, HVAC equipment, air compressors, etc. , by sensing phase loss, low voltage or phase reversal.

    With correct power applied, the DPDT output contacts transfer, and drop out when a fault condition or loss of power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and compressor motors.

    The DPDT output contacts allow the Model 2652 to be used in control circuits and alarm circuits. The automatic reset version can be converted to a manual reset, by adding a normally closed switch. The different voltage versions of the Model 2652 can be adjusted over a wide operating range. This unit is housed in an ABS plastic surface-mount case to reduce space requirements.

  • EX269

    Over and Under 3-Phase Monitor

    The Model 269 Over and Under 3-Phase Monitor continuously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal. This device features a solid-state voltage and phase-angle sensing circuit, which drives a SPDT output relay.

    The Model 269 is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay remains energizes. When a fault condition is sensed, the output relay drops out.

    The Model 269 does not require a neutral connection, and can be used on Wye or Delta systems. Each of the four voltage versions can be adjusted over a wide range. An adjustable trip delay (1-10 seconds) prevents nuisance tripping. OVER and UNDER voltage failure indicators aid in calibration and system troubleshooting.

    Smart Socket
    Type C - 480VAC

    Time Mark’s Smart Socket is the first socket which will allow monitoring of voltages up to 635 VAC with a socket-mounted Time Mark phase loss relay. The appropriate relay will allow monitoring for phase loss, phase reversal, low voltage and high voltage conditions. A key safety feature of the Smart Socket is it will not allow the voltage potential at the pin connections to rise to the full input voltage when the relay is removed. Two versions for the Smart Socket are available: one for 480 VAC and one for 575 VAC applications. The Smart Socket is designed to be used only with the Models B246, 253, 257B and 258B. Each of these relays is covered by Time Mark’s exclusive 5-Year Unconditional Warranty (Note: This product was previously designated as Model 98A544).
