The OL400W series delivers outstanding performance in the most challenging electrical environments. Access efficient and reliable operation via power switching IGBTs. Operate at full power when close-mounted thanks to 1U construction (2U for built-to-order 80 kV units). And save valuable rack space for large systems.

The OL400W series features Advanced Energy's proprietary Arc Count and Extinguish (ACE) system for managing systems where load arcing is possible, allowing you to protect your OL400W unit and load from damage caused by excessive arcing.


  • Enable significant rack space savings thanks to the OL400W series' compact construction
  • Reduce maintenance and safety risks with innovative arcing self-protection system
  • Ideally solve for 24 x 7 production processes where high reliability and performance are paramount
  • Reduce costs with flexible output options


  • Choice of nine different models or customer-defined derivatives upon request (minimum unit quantity limits)
  • High power density — 60 kV, 400 W in 1U format; 80k V 400 W in 2U format (custom only, built-to-order)
  • Unique Arc Count and Extinguish (ACE) system for managing load arcing
  • Efficient and reliable operation
  • RoHS Compliant to EU Directive 2011/65/EU
