DSP-DVR-M Digital 3 Phase Voltage Relay/Display meter seperated from Converter
Main Feature
- MCU based control, 8 Pin Type Compact size
- Easy Installation
- Panel Flush Mounting Type
- DSP-DVR-M :5 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 “a” in “out” mode
- 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 “a” in “out” mode
- 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
- ”dt”(trip delay time) mode is preset “OFF”
- 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
