    Under-Voltage Monitor

    The Model 2601 is a single-set-point under-voltage monitor. Input voltages above set-point will cause the output contact to energize and LED indicator to illuminate. Input voltages below the set-point will cause the output contact to de-energize and extinguish the LED indictor.

    The Model 2601 is available in AC or DC versions. AC models of the 2601 are not frequency sensitive and can be used on systems from 50 to 400 Hz. The voltage level is screwdriver adjustable over a wide operating range. Requires a standard 8-pin octal socket for mounting

    Under Voltage Monitor

    The Model 2602 Voltage Sensor is a rapid response device for sensing a low voltage condition on 120 VAC, 60 Hz, single phase power systems. Operating power is drawn from the same line being monitored.
    Upon sensing a voltage below 80 VAC, the internal relay, which is energized under normal operating conditions, will drop out.

    The solid-state sensor will respond in one-half of an AC cycle (8.33 ms. ), plus the flight time of the relay (20 ms. max. ). When the voltage rises above 84 VAC, an internal 10-second timer begins. When the time delay elapses the relay will automatically re-energize.

    Series Alternating Relay

    The Model 261 series Alternating Relay is designed for duplex pumping systems where it is desirable to equalize pump run time. The solid-state alternating circuit drives an internal electromechanical relay. A continuous power source and control switch are required. The control switch (float, pressure or other isolated contact) is connected between the L1 terminal and the control terminal. Each time the control switch is opened the output contacts will change states. Indicator lights on the case show the internal relay status. On the optional toggle switch versions, the toggle switch is set to the ALTERNATE position. Setting the switch to Load 1 or Load 2 will lock the relay in position, preventing alternation.
