The PRC300-300-S5NE from CUI is an Isolated Buck DC-DC Converter that converts an input voltage of 180 - 400 V to an output voltage of 5 V. It delivers an output power of up to 300 W and has an efficiency of 89%. This converter provides reinforced insulation with a high isolation voltage and reliable operation, even in electrically noisy environments. It has a durable construction and has an integrated baseplate for cooling and efficient thermal management. This converter has built-in over-current, over-temperature, over-voltage, short circuit, and input under-voltage lockout (UVLO) protection circuitries for safety during operation. It supports remote ON/OFF control and output voltage trimming for flexible configuration. This EN/IEC 62368-1 certified DC-DC Converter is available in a PCB-mount package that measures 57.9 x 61 mm.
