Working Principle

The SP-150-13.5 module is based on the half-bridge circuit topology, which is a basic building block of most AC/DC converters. The module utilizes a high-frequency transformer to isolate the input voltage from the output circuit. The input voltage is rectified by two diodes and filtered through a capacitor to provide a DC voltage at the input to the primary side of the transformer. On the secondary side of the transformer, the voltage is rectified and regulated by the control circuit. The control circuit monitors the output voltage and maintains it within the specified output range. Furthermore, the module is equipped with protection circuitry to prevent damage in case of short circuit, overvoltage, and reverse polarity.

The SP-150-13.5 is an efficient and reliable solution for powering various industrial applications; it is designed to provide a regulated DC output voltage with a high level of electrical isolation.
