Ningbo Huaguan Electronics Co. Ltd has released its JQX-54FE and JQX-54FW high-capacity electromechanical relays that have a contact rating of 0.1A, 5Vdc; 25A, 250Vac; or 20A, 277Vac.

The relays provide a switching power of 6.38kVA with a maximum switching voltage of 300Vac, and can withstand voltage surges up to 10kV. The units have an insulation resistance of 1 gigaohms, contact resistance of 500 milliohms, dielectric strength of 1kV (between contacts) and 5kV (between contacts and coil), and shock endurance between 10G and 100G. The JQX-54FE and JQX-54FW relays have operating and release times of 20ms and 10ms, respectively.

Rated at 5-, 6-, 9-, 12-, 24-, or 48V, the devices have a coil power consumption of 0.9W and coil resistance of 27.8-, 40-, 90-, 160-, or 640 ohms, or 2.56 kiloohms or 13.44 kiloohms. With a measurement of 30.4-by-16-by-26.5mm, they have a mechanical operating life of 10 million cycles and an electrical life of 100,000 cycles. Operating temperature range is from -33C to 55C.
