Product Details

  • Microprocessor based Over Voltage Relay 4W

    Model No : LVM-03

    All the line voltages are monitored and sensed simultaneously using three independent
    scale down potential transducer this low level ac signal is subjected to signal condition,
    which includes surge suppressors and harmonic filter, filtered signal is fed to the ADC of the
    industrial grade pic micro controller, When the sensing voltage level exceeds the user set
    value f or under or over voltage, Digital Microcontroller based definite-time under voltage
    (uv) and over voltage (ov) relay/line voltage monitor(LVM) gives an output signal in the form
    of relay change over for tripping/alarming.


    • Site selectable system voltage
    • Continuous display of the measured voltage parameter
    • 16 character 2 line LCD display with back-lit
    • Accurate reading for balanced and unbalanced load
    • Wide range of auxiliary input for both AC & DC
    • Independent contacts for both Under & Over voltage
    • Self reset & site selectable reset gap
    • Built in fixed instantaneous Under & Over voltage highest trip
    • User friendly setting modes using key pads
    • Low power consumption
    • Tropicalized design using micro controller & Ideal for industrial environment
