Description:

The toroidal construction inherently reduces stray fields, increases efficiency and minimizes

size compared to traditional EI transformers. The addition of a Flux Band further reduces the

remaining stray fields.

The shield between Primary and Secondary improves safety, reduces

common mode signals and minimizes leakage current. Built with a Class F (155°) insulation

system.

A 140°C self-resetting thermal switch is included in each primary.
