POWER TRANSFORMER
CHASSIS MOUNT :
TOROIDAL MEDICAL SERIES
VPM24-4170
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.
140°C self-resetting thermal switch is included in each primary.
