HE-R Series Power Relays for Charging Station Applications
Panasonic's compact size 40 A power relays are ideal for energy management applications
Panasonic'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.
- 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
- Three-phase AC chargers
- Industrial inverters (three-phase)
- Industrial welding machines
- Solar inverters
