The DCNEV150-MA is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a SPST-NO contact arrangement, 150A continuous carry rating, and 900V DC voltage rating. It includes an auxiliary circuit rated for 2A at 30V DC or 3A at 125V AC, and polarized load terminals. The contactor is sealed to IP67, operates from -40°C to 85°C, and uses a coil economizer with PWM to reduce holding power. It has M8 silver-plated copper terminals, bottom mounting with #10 compression limiters, and mounting torque of 1.7-3.3 Nm. Coil voltage range is 9-36V DC, with maximum inrush current of 3.8A. It meets UL File No. E510407 and is manufactured under IATF16949 certification. Weight is 0.43 kg.
The DCNEV150 Series 900V 150A High-Current High-Voltage DC Contactor Relay is designed for electric vehicle (EV) and eMobility applications, including 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 150A 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 high-current relay that allows higher make/break voltages and no electrical arc leakage.This model of the DCNEV150 Series electric vehicle contactor (DCNEV150-MA) features polarized contacts for optimal cycle life when used in polarized electrical systems. Additionally, this model features an auxiliary circuit.
