OPAL Series – Low Voltage Transformers

To achieve 25-50% more savings than the DOE 2016 requirement, Powersmiths’ developed and implemented a design best practice called OPAL - Optimized Performance for the Application Load. Recognizing that the transformer has much more impact in an electrical system than just efficiency, OPAL considers the system as a whole, including managing impedance, arc flash, fault level, inrush, harmonics, and more. OPAL is possible thanks to the tight feedback loop between design, onsite manufacturing, & extensive ongoing real world operating performance verification. The result is more savings for the same dollar.

Powersmiths enables right-sizing of electrical infrastructure by offering a much broader selection of transformer kVA sizes. The capital cost, operating cost and footprint reductions can be dramatic – on the order of 30-50%, through smaller transformers, breakers, conductors, and distribution panels.

Powersmiths guarantees that every transformer we manufacture meets our published technical data, and furthermore, that this performance is met over the full term of the 32-year pro-rated warranty.

Many general-purpose transformers are purchased & installed because they have the lowest first cost, however, they carry a UL label on the basis of feeding only linear loads. Since most connected loads today are electronic with nonlinear profiles, a lowvoltage transformer needs to be K-rated to have a valid UL listing for most applications. E-Savers are appropriately K-rated.

By going meaningfully beyond the DOE 2016 baseline efficiency, the E-Saver contributes to green building, LEED®, Net Zero and carbon footprint reduction goals. Additional benefits include our ISO14001 certified manufacturing, integrated metering and ability to integrate with the Powersmiths WOW Sustainability Management Platform.
