Omron tunes 120A AC latching relay for electric vehicles

Omron Electronic Components has added to its range of AC latching power relays with devices that have interfaces for electric vehicle (EV) charge stations, PV inverters and lighting control. 

The G9TA AC range of power latching relays are designed for applications up to 60A maximum switching current. These G9TA relays feature 2mΩ contact resistance, 6kV impulse withstand voltage, 250VAC switching voltage, and 12VDC coil voltage. 

The G9TA AC power latching relays have an operating temperature range of -40°C to 85°C. The high magnetic latching force is responsible for providing vibration resistance. The G9TA measures 37.5mm x 33mm x 18mm.

The 120A G9TB AC relay is designed with high overcurrent capability and conforms to IEC62055-31 UC3 standards. The G9TB power latching relays have a silver-alloy contact material, 0.4mΩ contact resistance, 276VAC maximum switching voltage, and -40°C to 85°C operating temperature range.

The Omron G9TA is now available with M5 securing screw and welding (solder lug) terminals. G9TB with its larger power capacity is now available with M8 securing screw and welding (solder lug) terminals.

Steve Drumm, business development manager at Omron writes: 

“Our high power latching AC relays are widely used in smart metering applications … with these new connectivity options, customers can apply their favourable characteristics in a host of new applications, which demand secure load connections so that the current flow path is optimised and self-heating is minimised.”
