  • DIN Mount - LV Voltage Relay

    Model No : VD02-33

    Prok Dvs make STATIC OVER VOLTAGE (OV) AND UNDER VOLTAGE (UV) RELAY WITH PHASE
    FAILURE (SINGLE PHASING) AND PHASE REVERSAL RELAY for protection against under
    voltages, over voltages, phase failure, phase reversal and unbalance voltages caused
    due to transients such as inductive load switching and commutation voltage spikes etc.
    Prok Dvs Make STATIC OVER VOLTAGE (OV) AND UNDER VOLTAGE (UV) RELAY WITH PHASE
    FAILURE (SINGLE PHASING) AND PHASE REVERSAL RELAY available in five models i.e. VD-02,
    VD-03, VD-04, VD-05 and VD-06 for various applications. They are provided with fixed or
    variable voltage settings, auto reset, definite time delay fixed or variable settings.

  • DIN Mount - LV Voltage Relay

    Model No : VD03-33

    In motors operating at low loads, failure of any one phase causes over voltages, which
    may cause rupture of insulation leading to motor burn out. Low voltage will cause
    synchronous motors to come out of synchronism at 75% of rated voltage. Induction
    motors may stop when voltage falls below 70%. Over voltages may occur due to
    defective voltage regulator, over speeding, caused by sudden drop in load on account of
    this di-electric property deteriorates. In single phase supply low voltage may cause over
    load on supply cable and thermal damage to insulation of windings.

  • LV Voltage Relay

    Model No : DMPVR-03

    Applications :

    • Protection of Synchronous and induction motor of any HP Rating
    • Protection of Generators, AMF switched Board
    • Transformer Feeder Panel
    • Distribution Boards
    • Voltage Regulators
    • Protection of UPS and Single phase application

  • AC Voltage Monitor

    Model No : VM-2D

    Prok dv’s AC Voltage Monitor is a microprocessor based voltage monitoring
    and supervision relay for polyphase systems. It can monitor both Under and
    Over Voltage conditions in the system. Both Under and Over Voltage are
    associated with definite time tripping characteristics. It has wide range for
    UV and OV settings as well as operating characteristics on the occurence
    of fault.
