Omron Electronics Components Europe is entering the high-power relay market with a new 100A device that features exceptionally low heat generation due to an ultra-low contact resistance. The new Omron G7EB is intended for distribution in power conditioning systems (PCS) and test equipment such as semiconductor testers.
Omron's G7EB relay can switch up to 100A at 800Vac. A key feature is the ultra-low contact resistance: at just 5 milli-ohms, these products lead the industry by significantly reducing heat generation within the component. This not only improves reliability by reducing thermal stress on the device and surrounding circuitry, but also minimises wasted energy. As a result, the G7EB experiences a temperature rise of around 40°C at a load current of 100A, as opposed to over 80°C in competing products.
PCS projects typically use three or more of these relays, and with its compact size (40.5 x 50.5 x 37mm), the Omron device helps to reduce the size of the system. Further space savings at system level are possible by virtue of the smaller heat sink specifications that result from the "cool" operation of the component. Omron offers the new G7EB with standard or proprietary pin layouts.

According to Andries de Bruin, Senior European Product Marketing Manager at Omron, "The distribution market for PCS is growing rapidly, driven by the trend towards micro-generation from renewable sources. Thechallenge in these high-current projects is to control heat generation, a challenge Omron addresses directly with this new design, which is ideal for emergency shutdown and other high-current applications.
