The DCNEV250-F is a high-current, high-voltage DC contactor relay rated for 250A continuous carry and 900VDC, designed for electric vehicle and eMobility applications such as battery power supply and charging stations. It features polarized load terminals with M8 silver-plated copper connections, a 72V DC nominal coil voltage with a 48-95V DC operating range, and a coil economizer that reduces holding power via PWM. The device is sealed to IP67, uses a gas-filled arc chamber to mitigate arcing, and has a SPST-NO contact arrangement. It mounts via #10 bolts with a torque of 1.7-3.3 Nm and measures 80.7 mm in length. The contactor operates from -40°C to 85°C, complies with IATF16949, and is UL Recognized under File No. E510407.
The DCNEV250 Series 900V 250A High-Voltage DC Contactor Relay is designed for electric vehicle (EV) and eMobility applications, including charging station, battery power supply, DC power control, circuit protection, and other switch control applications. The high-current, high-voltage relay can also be used in uninterruptible power supply and other electronic control systems.A coil economizer greatly reduces coil power and heating after the contactor is energized. Once the contactor is energized, it takes minimal coil power to keep the contacts closed due to Pulse Width Modulation (PWM) reducing the average power delivered by pulsing the electrical signal.This 250A relay also features a magnetic arc blowout design that dissipates electrical arc between the contacts within an IP67 sealed, gas-filled arc chamber. This design creates a safe EV contactor that allows higher make/break voltages and no electrical arc leakage.This model of the DCNEV250 Series high-voltage DC contactor (DCNEV250-F) features a 72V dc coil voltage rating and polarized contacts.
