AEV250 Series

Curring rating: 250A

Voltage rating: 12 - 900 VDC

AMI, Inc. AEV250 Series Curring rating: 250A Voltage rating: 12 - 900 VDC.. Product #: AEV250

AEV250 Series

Brand: AMI, Inc.
Product Code: AEV250

Application:

AEV250 Series is used for charging (pile) station, battery power supply, DC power control, circuit protection and other electric vehicle power switch controls. Also it could be widely used

Product Features:

  • HIGH CURRENT AND HIGH VOLTAGE: Contact chamber is filed with inert gas to minimize arcing, up to 900VDC
    load is available.
  • COMPACT STRUCTURE, LOW NOISE: Contact design yields reduced unit size, low noise while carrying or switching currents.
  • COIL ECONOMIZER: Built-in coil economizer – only 1.7W hold power @12VDC and it limits back EMF to 0V.
  • HIGH SAFETY: There is no arc leakage due to tight sealing.
  • HIGH RELIABLE CONTACT: Stable contact resistance no matter how harsh environment with sealed contacts.
  • NO SPECIAL REQUIREMENT FOR MOUNTING: Light weight actuator is less impacted by gravity with no special mounting orientation requirements.
  • VARIOUS APPLICATION: Application includes battery switch and standby equipment, DC power control, circuit protection, etc.
  • COMPLY WITH EU ROHS DIRECTIVE (2011/65/EU)
