Panasonic — HE Relay Series

Panasonic

 

Panasonic’s HE Relay Series use less operational power consumption through low coil holding voltages which can be implemented through pulse width modulation.

This is critical for energy conscious devices found in energy management applications. Panasonic’s HE Relays have high carry current capability which allows them, in certain applications, to replace traditional Contactors with related benefits to being smaller in size, less expensive, using less operating power, and being PCB mounted. Applications where Relays are being used to replace Contactors are becoming more common in designs for solar and industrial inverters as well as in UPS systems.
