DC Module: Maximum Durability.

Liquid-cooled, Bidirectional DC-DC Conversion

With a power rating of up to 750 kW per module, EPC’s liquid-cooled DC-DC modules pack the ability to perform in the harshest environment and provide years of reliable service.

Our DC-DC converters are compatible with a wide range of DC sources, including DC generators, ultra-capacitors, batteries (Lithium, lead-acid, flow, etc.), as well as fuel cells. By connecting a wide range of DC voltage levels, EPC DC-DC modules enable highly scalable power conversion in your application.

Key benefits:

  • Wide boost range
  • No dropout voltage constraint
  • Multiport DC inputs (optional)
  • Fully bi-directional
  • UPS, energy storage & fuel cell
  • Integrated liquid cooling for maximum durability
  • Investment Tax Credit may apply for when used for wind and solar generation
