The G7EB is aimed at distribution power conditioning systems (PCS) as well as test equipment such as semiconductor testers.
It can switch up to 100A at 800Vac. A key feature is the ultra-low 5 milli-ohm contact resistance, which greatly reduces heat generation within the component. This not only improves reliability by reducing the heat stress on the device and the surrounding circuit, but also reduces energy wastage. As a result, the G7EB experiences a temperature rise to about +400C with a 100A carry current, as opposed to +800C for competing designs.
PCS designs commonly feature three or more of this type of relay, and the Omron device helps reduce system size with its compact dimensions of 40.5 x 50.5 x 37mm.
The reduced requirement for heat sinks as a result of its cool operation yields further space savings for the system designer.
Omron is offering the G7EB with both industry standard and Omron proprietary pin layouts.
