Strong Points
Function
The OPAL-EV design delivers top performance for EV Charger applications. Features include from minimizing idling losses when there are no cars charging, to leading efficiency under heavy charging load, as well as the rapidly fluctuating loads in between. Powersmiths leverages its design best practice called OPAL – Optimized Performance for the Application Load, which in addition to efficiency optimization, considers the system as a whole, including load profile, impedance, arc flash, fault level, inrush, harmonics, and more. One of the achievements is very quiet operation – which can be an important consideration. Verified Performance is achieved by tight feedback loop between design, onsite manufacturing, and extensive real-world testing.

Advantages
Expandable kVA selection enables right-sizing
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.
Guaranteed Performance over 32 years
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. Being able to trust that savings are both real and long-term is part of why organizations choose Powersmiths.
K-Rating requirement
Many general purpose transformers are purchased and 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 low-voltage transformer needs to be K-rated in order to have a valid UL listing for most applications today. E-Savers are appropriately K-rated.
Environmental / Green Building / LEED® / Net Zero
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.
Metering & Arc Flash options
Integrated metering can provide information about capacity utilization, load profiles, power quality and energy use.
The lockable hinged door and our patented 360º Rotatable IR Port™ options, both provide quicker maintenance access and reduce arc flash safety risks.
High Performance Transformers for Electric Vehicle (EV) Charging Applications
The OPAL-EV Series transformers significantly support Net Zero Energy and LEED goals by:
- Reducing operating losses by 15-30%, lowering building energy consumption and renewable energy offset needs.
- Offering integrated energy metering/logging options, allowing EV Charger energy use to be subtracted from the Net Zero energy building calculation, reducing the required renewable capacity and cost.
