Product Datasheet DCNEV150 SERIES HIGH CURRENT HIGH VOLTAGE DC CONTACTOR RELAY Specifications Overview Amperage: 150A Continuous Carry Housing: Nylon UL 94-V0 Voltage Rating: 900V Output Connectors: M8 x 1.25 High Current Connections Connectors: Wire Leads for Control Circuit Ingress Protections: IP67 Operating Temperature: -40C to 85C Circuity: SPST NO Working Voltage: 9-36V DC Max Coil Inrush Current: 3.8A Mounting: 10 with Compression Limiters Size: Reference Dimensions on Page 2 Description Mounting Bolt Torque: 1.7 - 3.3 Nm (15- 30 in-lb) High current and high voltage DC contactor relays for electric Contact Torque: 8.8 - 11 Nm (80-100 in-lb) vehicle applications such as battery power supply, DC power Terminals: M8 Silver Plated Copper control, circuit protection, and other switch controls. Can also Approvals: UL File No. E510407 Recognized be used in uninterruptible power supply and other electronic control systems. Are available with polarized and non- Features and Benefits polarized contacts to best suit electrical systems polarity. Coil High current (150A) and high voltage (900V) contactor for Economizer greatly reduces coil power and heating after the EV Applications contactor is energized. Once the contactor is energized, it takes minimal coil power to keep the contacts closed due to Compact structure, helping reduce noise when turned on Pulse Width Modulation (PWM) reducing the average power Coil Enonomizer greatly reduces coil power and heating delivered by pulsing the electrical signal. Sealed IP67, gas-filled relay which mitigates arcing Applications No mounting orientation restrictions Battery Electric Vehicles Electric Maintenance and Designed and manufactured under the IATF16949 certification for Automotive Quality Systems. Transport Vehicles Hybrid Electric Vehicles Designed specifically for automotive applications.
