Conventional isolation transformers

Transformers with various primary and secondary voltage requirements, isolating capabilities, KVA ratings, insulation media are possible in a size and weight to fit your setup. (see table below)

Epoxy cast isolation transformers

A wide range of epoxy cast transformers is available with primary voltages from 120 V to 240 V, isolation voltages of 30 kV DCor 50 kV DC, standard VA ratings from 100 VA to 1000 VA and capacitance from 70 pF to 140 pF. Epoxy cast transformers are also available in custom configurations and builds.
