POWER TRANSFORMER CHASSIS MOUNT : TOROIDAL MEDICAL SERIES VPM24-10420 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. Electrical Specifications (@25C) 1. Maximum Power: 250VA 2.
