Omron's G9KB bidirectional DC power relay is specifically designed for new renewable energy systems. It is also the first matching product to mark the manufacturer's new focus on tackling the challenges of climate change and, in particular, promoting the transition to zero-emission fuels. The PCB power relay enables high-power bidirectional DC switching for battery energy storage systems (BESS), which allow households or electric vehicles (EVs) to use renewable energy separately from its generation via DC wallboxes.
Steve Drumm, Strategic Marketing Manager at Omron: "This new relay is a first part of our response to the next stage of the renewable energy market. This market requires reliable and safe switching between charging and discharging power from storage devices."
The G9KB (DC 600V/50A) features Omron's arc interruption technology (CAE), which 'stretches' the arc using the magnetic force of a permanent magnet placed near the contact point. This makes it suitable for the next generation of vehicle-to-home (V2H) and vehicle-to-grid (V2G) charging systems. In a V2H system, the relay allows an EV battery to be used as a power source for a household power system when the solar panels are not generating power. In a V2G system, on the other hand, the stored energy can be fed into the grid.
