Quad power – one eighth power loss: Panasonic Industry releases 40A printed HE-R relay for 3 phase systems with feedback contact. A perfect – and proven – match for EV charging wall boxes.


EV charging station infrastructure and the spread of efficient domestic wall boxes are more than ever decisive factors for the resounding success of electromobility. Correspondingly, the demand for compact, robust and highly performant components is high. When it comes to switching, there is good news from Panasonic Industry, as the new HE-R relay is the world’s first PCB based relay that can be used as the main switching element in 3 phase systems.

Being remarkably compact, it contributes to considerable space and cost savings. Each of the 4 NO contacts is able to switch 40A up to an ambient temperature of +85°C – also a result of the sophisticated thermal design and an unique low coil holding power. An optional NC contact as feedback contact can handle low level loads down to 10mA / 5VDC.

“Because of its outstanding ratio of size, power and robustness, the IEC62955 compliant HE-R relay is the perfect choice for contemporary and demanding AC/DC wall box designs”, claims Panagiotis Venardos from Panasonic Industry Europe. “The advanced technology inside the HE-R enables our customers now to control 3 phase systems directly on the PCB – that might not only be highly interesting for domestic wall boxes, but also for AC or DC charging stations and other fields of application, such as industrial automation or energy harvesting.”
