Triad Magnetics 250 Voltage·Ampere (V·A) Power VPM Series Toroidal Medical Transformer VPM24-10420

The Toroidal Transformer, Medical, 250VA from Triad Magnetics is designed for chassis mounting and features a toroidal construction that reduces stray fields and enhances efficiency. It has a maximum power rating of 250VA and supports input voltages of 100, 120, 220, and 240VAC at 50/60Hz. The transformer provides output options of 12VAC at 20.84A or 24VAC CT at 10.42A, with a typical voltage regulation of 6.2% from full load to no load. Safety features include a shield between the primary and secondary windings to minimize leakage current and common mode signals, along with a Class F (155¬8C) insulation system and a self-resetting thermal switch rated for 140¬8C. The transformer has a typical efficiency of 93% at full load and complies with medical safety standards, including UL 60601-1 and CE certification. Dimensions are 4.8 inches (123 mm) in outer diameter, 1.8 inches (45 mm) inner diameter, and 2.4 inches (60 mm) in height, with a weight of 2.5 kg. It comes with a metal mounting plate, rubber pads, and lead wires that are UL 1015 compliant. The product is RoHS compliant, meeting the requirements of the 2011/65/EU directive.
