ALEV50 Series

Current rating: 50A

Voltage rating: 12 - 750 VDC

AMI, Inc. ALEV50 Series Current rating: 50A Voltage rating: 12 - 750 VDC.. Product #: ALEV50

ALEV50 Series

Brand: AMI, Inc.
Product Code: ALEV50

Product Features:

  • HIGH CURRENT AND HIGH VOLTAGE: Nitrogen sealed contacts to minimize arcing, up to 750VDC load is available.

  • COMPACT STRUCTURE, LOW NOISE: Contact design yields reduced unit size, low noise while carrying or switching current.

  • HIGH SAFETY: There is no arc leakage due to tight sealing.

  • HIGH CONTACT RELIABILITY: Stable contact resistance no matter how harsh the environment with sealed contacts

  • NO SPECIAL MOUNTING REQUIREMENT: Light weight actuator is less impacted by gravity with no special mounting orientation requirements.

  • VARIOUS APPLICATIONS: Application includes battery switch and standby equipment, DC power control, circuit protection, etc.

  • OPTIONAL AUXILIARY CONTACT: Allows for contact position signal.

  • COMPLY WITH EU ROHS DIRECTIVE (2011/65/EU)
