DC 24V to 12V step-down converter

This compact buck converter accepts a DC input between 18V and 32V and delivers a regulated 12V output at up to 10A. It suits installers powering 12V devices from 24V vehicle or industrial supplies. The module measures 46mm by 32mm by 18mm and weighs 0.15 lb.

Replaces bulky linear regulators

Switching efficiency reaches 90 percent, so heat loss is far lower than with linear alternatives. The upgrade is worth it when the load draws several amps continuously and the enclosure has limited airflow. Built-in over-voltage, over-current, over-temperature and short-circuit protection with auto-recovery protects connected equipment.

Verify your 24V source and thermal limits

Confirm the supply stays within 18V to 32V under all conditions. If ambient temperature exceeds 45°C, reduce the output power or add heatsinking. Ensure wiring and connectors handle 10A at 12V without excessive voltage drop. The unit includes no fan, so free air circulation around the 46 by 32 mm footprint is required.

Questions about this item

What are the exact mounting dimensions of the 46 by 32 mm converter?

The unit measures 46 by 32 by 18 mm and weighs 0.15 lb, so it fits in tight enclosures and can be secured with small screws or double-sided tape.

Which wiring step do installers most often reverse on this 24 V to 12 V buck converter?

Connecting the 18 to 32 V DC source to the output terminals instead of the input terminals; the silk-screen labels show IN+ IN- and OUT+ OUT- to prevent this.

When should I add extra cooling for the 120 W module?

If the surrounding air exceeds 45 °C, reduce the load below 10 A or attach a heatsink and airflow to keep the case under the 80 °C maximum.
