Energy Efficiency & Cost Savings
As the pioneer of critical power distribution technology, ONYX leads the industry in high efficiency transformers. Backed
by over 35 years of magnetics experience, ONYX has one of the largest installed bases of high efficiency transformers
supporting global applications where lower operating costs, energy savings and the environment are a priority.
Lower Operating Costs
ONYX transformers are designed to deliver optimal high efficiency for lower operating costs. Exceeding national efficiency
standards (NEMA TP-1), PowerCube™ transformers deliver true energy savings under both linear and non-linear loads.
TP-1, US mandatory standard,
demonstrates energy savings that quickly
pay back the initial cost of replacing an
obsolete power transformer.
ONYX PowerCube™ incorporates
advanced engineering, meticulous
construction and the finest materials to
surpass TP-1 efficiency while in normal
operating load range.
Test Reports Verified to National Standards
To verify performance of actual efficiency, all ONYX transformers are provided with a serialized test report to
validate performance.
Engineering Capabilities
ONYX Power engineers are experienced in a variety of transformer requirements including: Delta Wye, Quad-Wye, Delta
Zig-Zag, Dual Zig Zag, autotransformers and medium voltage transformers.
Quick turnaround guaranteed – on all PowerCube™ designs, quotations and custom ratings
