## **POWER TRANSFORMER CHASSIS MOUNT : TOROIDAL MEDICAL SERIES** ~~TRIAD~~
## **VPM48-520**
## **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.
