The VPS28-900 is a 25VA chassis-mount Power Transformer with 115/230VAC @ 50/60Hz primary and 28V CT @ 0.9A series/14V @ 1.8A parallel secondary. It is designed to meet U.S. and international standards including CSA, IEC, VDE and UL requirements. The transformer consists of a dual bobbin design positioned inside an insulating shroud and constructed with UL approved high temperature material. This design eliminates the need for electrostatic shielding since there is minimal capacitance between coils when using a dual bobbin configuration. The primary and secondary are both electrically isolated from each other and from the core itself.
