Three Phase Transformers

three phase transformers

Lenco Electronics designs and manufactures a wide range of three phase isolation transformers and three phase autotransformers ranging from a 7VA to 75KVA. We also offer a wide range of termination systems including leads, lugs, bus bars, din rail or any combination your special application may require.

Lenco provides low cost samples along with design and manufacturing support from prototype through production, from 1 to 100,000+ units.

Custom built three phase autotransformer. Constructed per customer print, this 3 phase autotransformer in WYE configuration has 400/480V Primary with a 208V Secondary. Each coil has a 105 and 120 degree re-settable thermal fuse placed in the middle of the windings. Primary and secondary leads have ferrules crimped on the ends and tied in place to line up with a Din Rail style terminal block.

Lenco Electronics specializes in custom design of 3 phase isolation and 3 phase autotransformers up to 75KVA.

Custom 7VA 3 phase isolation transformer with single WYE conected 50Hz primary and single WYE connected secondary of the same voltage.
