V48C28M150BS2 Working Principle

The V48C28M150BS2 is a double-ended switching regulator, which is based on an open-loop topology. Its main components are an input diode bridge, a high-frequency switching transistor, an output filter and an optically isolated feedback loop. The input energy is first rectified by the diode bridge then switched by the high-frequency transistor. The voltage is then smoothed and regulated by the output filter and the feedback loop. The feedback loop provides an isolated signal back to the power electronics module, which controls the switching transistor and adjusts the output voltage to maintain an accurate regulated voltage.

The V48C28M150BS2 is designed with careful consideration of EMI/EMC parameters and radiated emissions so that both the input and output lines are in full compliance with EN 55011 and EN 55032 standards.
