This is the Cosel S1375590-01 / MCB-1202, a specialized printed circuit board assembly designed for industrial power applications. The board is expertly engineered to provide multiple, regulated DC outputs from a single input source. It prominently features two high-quality Cosel DC-DC converter modules: the ZUS25 2405, which converts a 24V input to a stable 5V output at 4A, and the ZUW25 2415, which provides a dual +/-15V output at 0.85A from the same 24V input. The board is equipped with dual edge connectors for robust system integration, a terminal block for power input, DIP switches for configuration, and status LEDs for diagnostics. On-board silk screen markings clearly indicate voltage test points and adjustment potentiometers for fine-tuning outputs, making it a versatile and user-friendly component for complex electronic systems.
