    Over or Under Voltage Monitor

    The Model 160B(R) Voltage Sensor is a single set-point voltage sensor. Input voltages above the set-point cause the output contacts to energize. Input voltages below the set-point cause the output contacts to de-energize. The dead band between pull-in and drop-out is less than 1%.

    Wiring connections are made to 1/4 in.; quick connect terminals. Standard versions have a 2-second restart delay. The R versions of the Model 160B have a fixed 5-minute short cycle delay. The Model 160B has a screwdriver adjustable set-point range of approximately 35% of the maximum voltage. The unit can be factory calibrated to meet specific requirements.

    AC versions of the Model 160B are not frequency sensitive and may be used in systems from 50 to 400 Hz. DC versions, or other short cycle periods, are available on request.

    Under Current Monitor
    0.1-1A

    The Model 171 is an AC current monitor for detecting undercurrent conditions. The monitor contains a proprietary microcontroller-based circuit monitoring current passed through an internal shunt resistor and driving an electromechanical SPDT relay. Two status lights are provided to indicate relay status, fault condition, and timing. An adjustable trip delay is provided to prevent nuisance tripping and an adjustable restart delay has been provided for applications requiring a delay to start an additional load.

    Over/Under Current Monitor
    5-25A

    The Model 173 AC Current Monitor is a single set-point AC current monitor. It can be used to detect either over current or under current, depending on whether the set-point is set above or below the input current. An LED indicator illuminates whenever the current is above the set-point. Two versions, either of which can be connected to 120 or 240 VAC, are available. One for current ranges up to 5 amps, the other for applications from 5 to 25 amps. For currents above 25 amps, matching CTs are available. The Model 173 is not frequency sensitive and can be used on AC currents from 40 to 400 Hz. The compact housing is surface mounted with 1/4 in. quick connect terminals provided for input and output connections.

    Over/Under Current Monitor
    25 -150A

    The Model 1732 AC Current Monitor is a single set-point current monitor. It can be used to detect either over current or under current, depending on whether the trip point is set above or below the input current. Dual LED indicators on the front or top of the unit give a clear visual reference for a fault condition. The Model 1732 generates its operating voltage from the monitored current line, so no external power supply is required. A current greater than 25 amps is needed to energize the internal relay. Momentary current above 150 amps will not damage the unit, however, the maximum current set-point is 150 amps. The Model 1732 is not frequency sensitive, and can be used on AC currents from 50 to 400 Hz.

    3-Phase Monitor with Trip and Restart Delays

    The Model 18 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 18 monitor will detect phase loss on a loaded motor even when regenerated voltage is present.

    This device consists of a microcontroller with a voltage and phase-angle sensing circuit, driving an electromechanical relay. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset. An adjustable restart delay prevents short cycling in compressor applications and an adjustable trip delay prevents nuisance tripping during power fluctuations.

    The Model 18 does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both FAULT and NORM condition indicators are provided to aid in adjustment and system trouble-shooting. The Model 18 is UL Recognized in the U.S. and Canada and is available with optional gold flashed silver contacts for low current applications.
