LXCVR-EV EV Charging Voltage Monitoring Relay

  • For use in electric vehicle (EV) charging applications
  • Trip thresholds aligned with BS7671:2018 Am. 1 – 2020, Sec. 722
  • Designed for 230VAC, single phase
  • Fixed Under/Over voltage Trip levels
  • Fixed Time delay
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount
  • UL Listed

Designed for EV charging applications that do not require the use of an earth rod, the LXCVR-EV monitors the single phase supply voltage to the charger, and in conjunction with a contactor, disconnects the supply to the charger if the voltage exceeds the fixed trip levels.

  • Monitoring function: Under/Over voltage
  • Monitored supply voltage: 230V AC (Order Code: 99-3501)
  • Trip levels (fixed): Under: 207V/Over: 256V
  • Hysteresis: ≈2%
  • Time delay (fixed): 4s
  • Output: SPDT 8A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5

Typical applications include:

  • Domestic single-phase EV charge points
  • Workplace AC charging installations
  • Destination AC charging equipment
  • EV charger OEM control panels

Key benefits:

  • Supports charging supply disconnection — The relay output can release an external contactor when a sustained under- or overvoltage condition is detected.
  • Simplifies production settings — Fixed trip levels and a fixed delay avoid the need to select voltage thresholds or timing during normal integration.
  • Avoids reacting to brief voltage changes — A fixed time delay qualifies normal under- and overvoltage threshold faults before the relay changes state.
  • Fits compact charging panels — The 17.5mm DIN-rail housing provides a compact voltage-monitoring component for an EV charger’s protection and switching arrangement.
