All PDUs Come Standard with OPAL™ Series Transformers: Application Efficiency Optimized with Managed Inrush Currents.
|OPAL™ Transformer Models||Load Range & Application||Savings vs. DOE 2016*||Winding Material **||Continuous Overload Capacity||K-Rating ***|
Most light loads, feeding electronic equipment in schools, offices, commercial, institutional, applications
Widely varied equipment or process loading, or load changes over time
|20%||CU||15%||K1, K9, K13|
High equipment loads. Pumps, elevators, etc. in labs, broadcast, datacenter, industrial etc.
|25%||CU/AL, CU opt.||20%||K13|
Harmonic mitigation for heavy harmonic-rich loads with high densities of electronic equipment
Heavy loads for extended hours. Process equipment, labs, broadcast, telecom, and some data centers
|35%||CU/AL, CU opt.||33%||K20|
Close to full continuous load. Labs, broadcast, telecom, and data centers, where overload capacity adds value, and energy rates and cooling costs are elevated
Solar Applications. Operating from full load for long hours to idling at night
|30%||CU/AL, CU opt.||20%||K20 but not required|
*Estimated average energy savings for each load profile vs. DOE 2016 minimum efficiency rated transformer
**CU=Copper, CU/AL=Copper Primary with Aluminum Secondary
***K-Rating per IEEE-C57.110. The high K-factor rating is not the goal of the design, but a consequence of the low current densities used to achieve the high loading efficiency goals.
