Data center transformers

Data Center Transformers IIoT-enabled active harmonic filters air core teactors current limiting reactors mini power centers clean power

As AI workloads, hyperscale facilities, and cloud computing accelerate, data centers require robust, high-efficiency electrical infrastructure to maintain continuous uptime and meet aggressive sustainability goals. We deliver engineered transformer solutions built for the demanding performance, thermal, and space constraints of modern mission-critical facilities.

Medium-voltage pad mounted and substation transformers (oil)

Engineered for the utility handoff, medium voltage transformers step down incoming high-voltage power to feed internal data center distribution systems safely and efficiently.

  • Mineral oil or FR3 fluid
  • Kirk key interlocking provisions
  • Dual voltage options
  • Bayonet fusing, current-limiting fuses, and/or isolation links
  • Gauges (internal or external)
  • Gauges with contacts
  • Sample valve (internal or external)
  • Viewing and IR windows

Medium-voltage substation transformers (dry)

Engineered for the utility handoff, medium voltage transformers step down incoming high-voltage power to feed internal data center distribution systems safely and efficiently.

  • Mission-Critical Reliability: Built to handle fast-ramping, high-density AI and hyperscale load profiles without compromising thermal or voltage stability.
  • Flexible Footprints: Customized designs adapt to site-specific spatial, environmental, and safety requirements across greenfield builds and retrofit projects.
  • Enhanced Outdoor Protection: Pair with specialized enclosures for outdoor deployments exposed to dust, moisture, and severe weather.
  • Smart Monitoring: Available with IIoT-enabled meters to track voltage, current, and harmonics in real time for predictive maintenance.

Low voltage & PDU transformers

Positioned closer to the white space, low voltage and Power Distribution Unit (PDU) transformers deliver clean, isolated power directly to sensitive IT infrastructure, server racks, and secondary equipment.

  • High Efficiency & PUE Optimization: High-efficiency dry-type designs reduce energy losses, lowering operating costs and helping data centers achieve lower Power Usage Effectiveness (PUE).
  • Power Quality & Isolation: Protects critical electronics by isolating sensitive IT loads from electrical noise, transients, and harmonic distortion generated by nonlinear UPS systems.
  • Modular Deployment: Compact designs allow seamless integration into row-level PDUs and localized mini power centers, facilitating dynamic scaling without upstream redesigns.
  • Reduced Thermal Stress: Engineered to perform under harmonic-rich load profiles to extend equipment lifespan and minimize uptime risks.
