The B40SR12424CC is a high-efficiency enclosed DC/DC converter designed for chassis mounting in harsh environments. Part of the B40SR series, it accepts a wide input voltage range of 18V to 60V and delivers a regulated 12.4V output at currents up to 24A. The device is rated at 300W (derated to 200W for input voltages below 27V) and features IP67 waterproof protection. It includes a built-in enable control pin on the primary side and does not include a fuse holder. The converter utilizes a Molex Mini-Fit Sr. connector interface and provides comprehensive protection features including input undervoltage lockout, output overcurrent, short circuit, overvoltage, and overtemperature protections.
