Fujitsu Announces EV Charging Relay

Fujitsu Components America, Inc. today introduced a high-voltage DC load switching relay series for the electric vehicle charging market with 13-percent higher voltage switching capability, 77-percent less power consumption, and a package size 40-percent smaller than similar, available relays. The FTR-E1 series is a compact, single-pole PC board relay available with 12VDC and 24VDC coils.It is nominally rated up to 30A, 450VDC (40A max/1hr), resistive, with 900mW power consumption.

The relay’s compact (43.6 x 28.3 x 36.8mm) package weighs approximately 75g, which is nearly 60-percent lighter than competitive devices. In addition, the FTR-E1 series also offers an electrical life of 10K operations at 20A, 450VDC resistive – nearly three-and-a-half-times that of leading products.

With a dielectric strength of 5,000VAC (1 min.) between coil and contacts, the FTR-E1 offers twice the insulation properties of similar relays. Non-polarized contacts enable it to switch between charging and discharging the load, making this relay well suited for use in on-board chargers and charging stations for electric and plug-in hybrid electric vehicles, string disconnection of photovoltaics systems, and high-voltage DC load control systems.

Available immediately, the FTR-E1 is lead-free, RoHS compliant, and cULus recognized. Pricing begins at $29.85 each for single- to 99-piece quantities.
