EVs and industrial electronic control systems need robust power management solutions. Our partner Littelfuse’s high-voltage dc contactor relays meet those needs while also providing high-current circuit protection. Our contactor relays come with continuous current ratings up to 500 A and maximum voltage ratings up to 1.8 kV dc. Some versions incorporate pulse with modulation (PWM) technology to reduce power demands for keeping contacts closed.
The main job of a relay is to enable remote switching within an electrical system. A relay allows switching of a high current circuit by a low current signal. This allows the relay to be placed close to the power source, or load to be switched, so that expensive high current cabling is minimized, while still giving easy access to the operator to turn the relay on or off. Common applications include EV charging stations, uninterruptible power supplies, and dc motor controllers.
