CE Marked  Single Phase Encapsulated
Series ES - 11 .250 kVA - 25 kVA

Series ES Single Phase Encapsulated Transformers are designed to comply with Domestic, North American, and European Union electrical and testing standards. Series ES are UL and Canadian UL Listed by Underwriters Labs. In addition, Series ES are CE Marked, and licensed by the German testing agency TÜVRheinland under License Number R 2679035.01.

Series ES transformers are the answer to your export needs. With the voltage combinations listed below, and built In approvals, the ES Series provide no-nonsense solutions for equipment destined for the European Community of nations.

Under EC guidelines, connecting transformers to line end load require finger safe connections. While other manufacturers provide leads, Dongan provides finger safe terminals on all ES- 11 transformers. This feature eliminates the necessity of a difficult, labor intensive installation of terminals in the wiring compartment by the end user.

The voltage combinations offered represent some of the most universally used. However and combination of primary and secondary incorporating voltages of 600 volts and below is available on a short lead time, special order basis. In addition, capacities up to 25 kVA and special temperature rise configurations can be furnished. Please consult your distributor, Dongan Representative or the factory for special ES Series transformer requirements.
