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.

The DCNEV150 Series electric vehicle contactor has a 12-24V dc coil rating and is available with or without an auxiliary circuit. This high-voltage relay is also available with polarized or non-polarized contacts, which allows you to optimize for the polarity of the electrical system.

Features and Benefits

  • High-current (150A) and high-voltage (900V) DC contactor for electric vehicles (EV), eMobility applications, and industrial machinery
  • Compact structure helps reduce noise when the contactor is turned on
  • Coil economizer greatly reduces coil power and heating with signal pulse width modulation (PWM)
  • Magnetic arc blowout design dissipates any arc between the contacts within an IP67 sealed, gas-filled arc chamber, allowing the relay to make/break higher voltages
  • Lightweight actuator is less impacted by gravity with no mounting orientation restrictions
  • Designed and manufactured under the IATF16949 certification for Automotive Quality Systems
  • Electric vehicle contactor features single-pole, single-throw (SPST), normally open (NO) circuitry

Applications

  • Battery Electric Vehicles (BEV)
  • Hybrid Electric Vehicles (HEV)
  • Material Handling
  • Electric Maintenance and Transport Vehicles
  • Industrial
