TE Connectivity AC Charging Relay Solutions

AC charging solutions allow for cost savings that make them a great choice for charging your car at home. In establishing a wide and accessible network of charging stations across the country, the trend mainly relies on domestic AC charging supplemented by DC charging options in the public area. The AC charging station supplies AC-controlled power to the converter built inside the car, and converts power from AC to DC and then feeds it into the car’s battery. This is the most common charging method for electric vehicles today and most chargers use AC power.

TE offers several relay solutions for single phase and three-phase AC charging stations and wall boxes, such as the Potter & Brumfield Relay T92 Series and T9V Series, and Power Latching Relay EW/TMR Series for the harsh environments that AC charging stations may endure.

TE Connectivity’s Potter & Brumfield Relay T9V Series is a fit for Onboard Charging System applications through demonstrated space savings, device performance, safety protection, and reliability.
