30-90V In To 12V Out 5A 60W Waterproof DC-DC Step-Down Buck Converter Module

This high-performance DC-DC step-down (buck) converter efficiently converts a 30V to 90V DC input into a stable 12V output at up to 5A (60W max). Designed for durability, its rugged, epoxy-sealed aluminum case and IP68 waterproof rating make it perfect for outdoor and high-humidity environments.

With a wide input range up to 90V, this converter is ideal for 72V battery systems, accommodating voltages up to 86V when fully charged—ensuring safe, reliable operation without the risk of overvoltage damage. Whether for electric vehicles, solar power systems, or industrial applications, this converter delivers dependable 12V power wherever you need it.

Operating Notes:

As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 4A at 12V (48W), and the input supply is only capable of providing 48V at 0.5A (24W), the maximum output voltage the converter will deliver is 6V (24W/4A).

Connection:

The red and black wires are the +V and -V inputs; the yellow and black wires are the +V and -V outputs.

Package includes:

• 1X 30V-90V DC Input to 12V DC Output 5A 60W Waterproof DC-DC Step Down Buck Converter
