Single-phase EI transformers

We manufacture single-phase transformers according to EN 61558 with welded or manually stacked EI core up to 1600 VA. Transformers can be supplied with taps on the primary winding and a different number of secondary windings according to customer requirements. The transformer can be connected using screw terminals, terminals with built-in fuse, terminals with FASTON connectors or a cable with a customer-selected connector; we can build a thermal fuse or bimetallic switch into the winding.

We have UL certification for single-phase EI transformers in category XPTQ2/8 (Transformers, General Purpose – Component) with a class F insulation system, this certification can be used for any combination of primary and secondary voltages up to 600 V.
