A high-voltage, DC load switching relay series for the electric vehicle charging market with 13% higher voltage switching capability, 77% less power consumption, and a package size 40% smaller than similar relays is now available.
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 mm x 28.3 mm x 36.8 mm) package weighs approximately 75 g, which is nearly 60% 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.
