  • Microprocessor based Under/Over Voltage Relay 4W

    Model No : LVM-11

    Prok dvs make AC Digital Microcontroller Based Definite-Time Under Voltage (UV) and Over Voltage (OV)/ Line Voltage Monitor (LVM) is a microcontroller based voltage monitoring and supervision  relay  for poly-phase system. It can monitor both under voltage (UV) and over voltage (OV) conditions in the system. Both under voltage (UV) & over voltage (OV) conditions are associated with definite time tripping characteristics. It has wide setting range of operating time on the occurrence of fault condition.

    DIGITAL MICROCONTROLLER BASED DEFINITE TIME UNDER VOLTAGE (UV) AND OVER VOLTAGE RELAY/ LINE VOLTAGE MONITOR(LVM) provides wide range of time delay for healthy resumption of the operating voltage. 

  • 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.
