POWER TRANSFORMER CHASSIS MOUNT : TOROIDAL MEDICAL SERIES VPM18-1390 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: 25VA 2. Input Voltages: 100, 120, 220, 240VAC, 50/60Hz 3. Output Voltages: 9VAC @ 2.78A or 18VAC CT @ 1.39A 4. Voltage Regulation: 10.3% TYP from full load to no load 5. Temperature Rise: 25°C TYP 6.
