    What Size DC-DC Converter Do I Need for 24V to 12V?

    Choose the converter based on the maximum current or power required by your 12V load.

    Required Output Current (A) = Total Load Power (W) ÷ 12V

    For example, a 100W load requires about 8.3A, so a 10A / 120W converter can be considered. If the load includes motors, pumps, fans, or other devices with startup current, choose a higher-current model to provide additional capacity.

    Model Selection Examples

    12V Load Required Current Model to Consider
    50W 4.2A 5A / 60W
    100W 8.3A 10A / 120W
    150W 12.5A 15A / 180W
    300W 25A 30A / 360W
    400W 33.3A 40A / 480W
    650W 54.2A 60A / 720W
    900W 75A 85A / 1000W

    Also make sure the converter's input range covers your actual 24V power source. This series accepts 18–36V DC input and provides 12V DC output. For multiple loads, add their maximum current requirements together before selecting a model.

    FAQ

    Q1: How can I check if the converter is working properly?

    Use a multimeter to verify the output voltage under load. A stable voltage indicates proper operation.

    Q2: Can I power multiple devices from one converter?

    Yes, as long as the total current draw is within the converter’s rated output current.

    Q3: Why is the DC step down converter getting warm?

    Heat is normal under moderate to high loads. Ensure there is airflow or a heatsink if operating near max rated current.
