We supply series of UI flat encapsulated transformer, UI30,UI39, UI48 etc with good price and high quality. We design such transformer with dual primary and dual secondary, the working voltage 115V/230V and rated frequency 50/60Hz and also with a very wide range of output voltage. Power range from 6VA to 60VA Typical design is with 2x115V primary for 115V or 230V input at 50/60Hz and dual secondary with two identical output voltages. Approved according to EN 61558. VDE 0570 Vacuum cast Safety class II Protective system IP 00 Absolutely short circuit proof (*ukf). or conditionally short-circuit proof (*bkf) through built-in temperature fuse, or not short-circuit proof (*nkf) but protected by external fuse on primary or secondary The Low Profile series is ideal for applications with component height restrictions such as where a close spacing between boards is needed. encapsulated transformer with Dual primary and Dual secondary design, working voltage 115V/230V, , dielectric strength 4000Vac
