POWER TRANSFORMER
CHASSIS MOUNT :
TOROIDAL MEDICAL SERIES
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 the primary.
