LPRD/2 – THAI TECHNIC

LPRD/2

  • Under voltage with restart delay
  • Selectable nominals for popular 3-wire or 4-wire supply voltages
  • Detects incorrect phase sequence, phase loss and neutral loss (4-wire mode)
  • Adjustable Trip level and Time delays
  • DPDT Relay output
  • 17.5mm wide, DIN Rail mount

The product monitors it’s own three-phase supply and can be set for either 3-wire or 4-wire monitoring. For the output relay to energise, all phases (and neutral – if applicable) must be present, phase sequence correct and measured phase voltages above the set trip level. If any of these conditions are not met, the relay will de-energise. An adjustable restart delay allows the user to set a period of time before the relay is allowed to re-energise.
