DSP-DVR Digital 3 Phase Voltage Relay/Display Meter unified with Converter
Digital 3 Phase Voltage Relay/Display Meter unified with Converter
Main Feature
  • MCU based control, 8 Pin Type Compact size
  • Easy Installation
    • Panel Mounting Type
    • DSP-DVR :4 digit window
  • Operation based on direct line voltage detection
    • Protection : Over/Under voltage, Phase Loss, Reverse Phase, Voltage Unbalance
    • Indication : Voltage[Line/Average], Frequency
    • Time-Voltage operational characteristic → Definite / Inverse
  • Over/Under Voltage Protection
    • Rated Line Voltage → 100 ~ 500VAC
    • Over Voltage protection Range → within (+) 20% to line voltage
    • Under Voltage protection Range → above (–) 20% to line voltage
  • Possible to preset operation time for over/under voltage each, repectively
  • Perfect check for initial line state
    • ”dt”(trip delay time) mode is preset “OFF”
      • Preset “a” in “out” mode
        • Main trip output(95-98) is energized (Open → Close ) in case the rated line voltage with normal forward phase state is sensed initially
        • Main trip output(95-98) is trip(Close → Open) within 0.5sec after energizing(Open→Close) if the initial state is under phase loss
        • Main trip output(95-98) is trip(Close → Open) after operational preset time is elapsed from instant energizing point(Open→Close) as showing a trip cause if the initial line state is under over/under voltage,reverse phase, voltage unbalance
        • v.OFF is shown in case the line voltage is not sensed initially or voltage is dropped to zero(0) while the normal operation is doing
      • Preset “b” in “out” mode
        • Main trip output(95-98) is not energized (Open → Open ) even if the rated line voltage with normal forward phase state is sensed initially
        • Main trip output(95-98) is trip(Open → Close) within 0.5sec if the initial state is under phase loss
        • Main trip output(95-98) is trip(Open →Close) after operational preset time is elapsed as showing a trip cause if the initial line state is under over/under voltage,reverse phase, voltage unbalance
        • v.OFF is shown in case the line voltage is not sensed initially or voltage is dropped to zero(0)
    • ”dt”(trip delay time) mode is preset a value(time)
      • Preset “a” in “out” mode
        • Main trip output(95-98) is energized (Open → Close ) after “dt” is elapsed in case the rated line voltage with normal forward phase state is sensed initially
        • Main trip output(95-98) is still opened(not trip) even after “dt” is elapsed if the initial state is under phase loss,also “PL’is shown
        • Main trip output(95-98) is energized (Open → Close) right after “dt” is elapsed if the initial line state is under over/under voltage, voltage unbalance, and then it is trip(Close → Open) after operational preset time is elapsed from energizing point(Open→Close) as showing a trip cause
        • v.OFF is shown in case the line voltage is not sensed initially or voltage is dropped to zero(0) while the normal operation is doing.
        • ”rP” is shown as main trip output(97-98) is still opened(not trip) after operational trip time (0.5sec) without concerning with “dt” if reverse state is sensed initially
      • Preset “b” in “out” mode
        • Main trip output(95-98) is not energized (Open → Open ) in any case
        • Main trip output(95-98) is trip (Open → Close) after “dt” is elapsed if the initial state is under phase loss as “PL’is shown
        • Main trip output(95-98) is trip (Open → Close) right after “dt”is elapsed as showing a trip cause if the initial line state is under over/under voltage, voltage unbalance
        • v.OFF is shown in case the line voltage is not sensed initially or voltage is dropped to zero(0)
        • ”rP” is shown as main trip output(97-98) is still closed(not trip) after operational trip time(0.5sec) without concerning with “dt” if reverse state is sensed initially
  • 3 phase line voltage/average voltage and /or frequency is shown ordery in every 3sec
  • Stored the information for latest 8 trip event
  • Reset after a trip : auto or manual
  • Self-diagnostics to check if this relay is ready to work or not
