From VAR Partner to Global Standard for Tech Giant: Repeatable Dry‑Type Platform for high-demand PDUs
As power demands intensify … the real advantage comes from solutions that scale without sacrificing performance.
BACKGROUND:
Quality Electrical Systems (QES) has been in operation for over three decades and continues to be a rapidly growing electrical equipment manufacturer with more than 350,000 square feet of industrial manufacturing space in Utah. As demand surged for their PDUs, QES needed a reliable partner that could scale quickly while maintaining uncompromising quality and performance.
THE CHALLENGE:
QES’s legacy transformer supplier struggled to keep pace with increased demand, resulting in:
- Missed deadlines and late deliveries
- Inconsistent build quality (overheating, excessive noise, etc.)
- Limited engineering support from legacy supplier
To sustain their growth trajectory, QES required more than a vendor … they needed a strategic manufacturing partner capable of delivering high‑quality, scalable options.

THE SOLUTION:
PDM designed and manufactured custom dry‑type transformers engineered specifically for seamless integration into QES’s smaller footprint PDUs.
PDM engineered a repeatable transformer platform optimized for thermal efficiency to reduce the footprint of their PDUs, creating a more compact, space-efficient design without sacrificing performance.
PDM ADVANTAGE:
PDM delivered a solution that solved QES’s immediate supply‑chain challenges while positioning them for long‑term operational growth:
- VPI construction with total Epoxy Immersion enabling superior heat dissipation and quieter operation under load
- Higher-grade build quality for improved reliability. Stub alignment consistency and vibration-absorbing mounting pads provided easier hard-bus connection
- Consistent, on-time delivery to support production planning
- Scalable manufacturing capacity to meet growing volume demands
THE RESULTS:
QES’s PDUs – equipped with PDM dry‑type transformers – have since been adopted as the standard solution by their multi–national technology company client, validating both performance and scalability.
The partnership has generated multiple 100+ piece orders for PDM, with continued growth expected as deployments expand.
