High-voltage relays target electric vehicles
The FTR-E1 relays furnish contact ratings of up to 30 A at 450 VDC (40 A maximum/1 hour) resistive and consume just 900 mW at the rated coil voltage. Their compact package is 43.6×28.3×36.8 mm and weighs approximately 75 g, nearly 60% lighter than competitive relays, according to the manufacturer. In addition, the parts achieve an electrical life of 10,000 operations at 20 A, 450 VDC resistive.
Devices provide a dielectric strength of 5000 VAC (1 minute) between coil and contacts and 2500 VDC (1 minute) between open contacts. Insulation resistance is 1000 MΩ at 1000 VDC. Nonpolarized contacts enable the relays to switch between charging and discharging the load, making them well-suited for use in onboard chargers and charging stations for electric and plug-in hybrid electric vehicles, string disconnection of photovoltaic systems, and high-voltage DC load control systems.
Prices for the FTR-E1 series relays start at $29.85 each for 1 to 99 units.
