HE-R Series Power Relays for Charging Station Applications

Panasonic's compact size 40 A power relays are ideal for energy management applications

Image of Panasonic's HE-R Series General Power RelaysPanasonic's HE-R series is an energy management relay designed for three-phase AC charging using its 4FormA contacts arrangement which allows for the cut-off of all three phases plus neutral simultaneously. The auxiliary contact is used to detect welding failures of the primary open contacts. The HE-R series relay also features a low coil-holding voltage for reduced power consumption and is PCB mounted to ease board assembly. This relay also meets the necessary short-circuit current rating (SCCR) to pass UL and IEC standards for EV charging equipment, making it suitable for charging stations, industrial equipment, and more.

Features
  • High-capacity switching and current carrying capabilities
  • RoHS compliant
  • Low operating power (0.49 W) using reduced coil holding voltage
  • SCCR can withstand a peak current of 1.85 kA with I2t of 4.5 kA2s (compliant with IEC62955)
  • Mirror contact structure with auxiliary contact allows for welding detection function compliant with IEC60947-4-1 standard
Applications
  • Three-phase AC chargers
  • Industrial inverters (three-phase)
  • Industrial welding machines
  • Solar inverters
