LPRC/2

  • Under and Over voltage monitoring (Window)
  • Selectable nominals for popular 3-wire or 4-wire supply voltages
  • Detects incorrect phase sequence, phase and neutral loss
  • Adjustable Trip levels and Time delay
  • 2 x SPDT Relay outputs
  • 17.5mm wide, DIN Rail mount
  • UL Listed

The product monitors it’s own three-phase supply and can be set for either 3-wire or 4-wire monitoring. There are two independent relays provided with one assigned to under voltage monitoring and other to over voltage monitoring. In addition to the measured voltages, all phases (and neutral if applicable) must be present and phase sequence correct for the relays to energise. If any of these conditions are not met, the relay(s) will de-energise.

  • Monitoring function: Under/Over voltage
  • Monitored supply voltages (2 versions available):
    • LV version: (3-wire) 110V, 208V or 220VAC/(4-wire) 63.5V, 120V or 127VAC (Order Code: 99-4204)
    • Standard version: (3-wire) 380V, 400V or 415VAC/(4-wire) 220V, 230V or 240VAC (Order Code: 99-4203)
  • Trip level: Under: 75 – 95%/Over: 105 – 125%
  • Hysteresis: ≈2%
  • Time delay: 0.2 – 10s
  • Output: 2 x SPDT 5A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5
