This is a DC-DC step-down converter module that takes an input voltage of DC36V-60V and converts it to a regulated output voltage of 24V. It can provide a maximum output current of 2A and a maximum output power of 24W with a conversion efficiency of 94%. The module features overcurrent, overtemperature, and short circuit protection, which are self-recovering. It is also waterproof, dust-proof, and shockproof, making it suitable for use in harsh environments. The module is small in size, measuring 46x32x18mm (not including installation ear) and weighs 53g. It is enclosed in an aluminum enclosure. The wiring is simple, with the input red wire (+) and black wire (-) and output yellow wire (+) and black wire (-). The wire length is 15CM. However, the module has no reverse protection, so wiring must be done carefully.
