What is a PCB Power Relay?

PCB Power Relay Definition

About PCB Power Relays

Relays mainly used for more than 3A load switch, and equipped in household appliances, such as refrigerators, washing machines, and AV device, as well as various FA equipment, industrial equipment, and household equipment.

PCB Power Relay Features

Power relays for printed circuit boards offer superior performance in high-capacity load switching in the power supply system owing to its material that can resist to contact arc and single contact structure (see figure). These power relays also retain excellent performance in contact volume and contact pressure.
In addition, these power relays comply with various safety standards. The products line-up includes relays that have enhanced insulation distance between coil contacts
