AEP Series: High Voltage, High Current Cut-Off Capable, Compact Power Relay

10A PC board 10A TM 20A TM 80A 200A 300A
RoHS compatible UL CSA Recognition*1

*1 (10A, 20A and 80A types)

Features

  • High-voltage, high-current control capable
    400V DC high-voltage switching and 1,000V DC cut-off has been achieved thanks to a sealed construction with mixed hydrogen gas and the magnetic arc motion through use of a permanent magnet.
  • Compact & Low Operating Sound
    By using a capsule contact mechanism that is enclosed with hydrogen gas, high capacity cutoff is possible even with a tiny contact gap. There is little operating sound, which does not change even when large currents are cut off.
  • Arc space unnecessary
    The enclosure box can be made smaller thanks to an arc-space-free construction from which the arc will not get out.
  • Safety
    Since the contacts are enclosed in a sealed capsule structure, the arc will not get out, which ensures safety.
  • High contact reliability
    The contact part is hermetically sealed with H2 mixed gas, hence the contact resistance remains stable regardless of the ambient conditions.
  • Mounting direction is not specified
    The weight of the movable parts is light, and also the restoring force is large, hence the relay is relatively unaffected by gravity.
  • Wide selection of models available.
    Types include PC board type (10A), TM type (10A and 20A), Lead wire type (200A) and Connector type (80A and 300A).
  • Standard compliance
    The 10A, 20A, 80A type is UL/C-UL standard certified.
