Converts 30-60V input to 12V 10A output with 95% efficiency and full waterproof protection

  • Converts 36V or 48V sources to stable 12V 10A output
  • Synchronous rectification reaches 95% efficiency with only 50mV ripple
  • Smart chip provides over-current, over-load, short-circuit and over-heat protection
  • Sealed aluminium housing is 100% waterproof, dust-proof and shock-resistant
  • Operates reliably from minus 40°C to plus 80°C

What this converter does

The KEHIPI unit steps a 30V to 60V DC source down to a steady 12V output at up to 10A, delivering 120W of continuous power. It is built for golf-cart electrical systems and similar 36V or 48V battery banks that need to run 12V accessories.

Check your source before ordering

Verify that your battery pack or supply stays within the 30V to 60V input window and can provide the required current. Confirm the load you intend to power draws no more than 10A at 12V. Ensure the wiring can handle the input and output currents and that the polarity matches the converter’s terminals.

How it fits into the build

The non-isolated buck module mounts in a compact aluminium shell that is epoxy-potted for 100% waterproof, dust-proof and shock-resistant operation from -40°C to 80°C. Synchronous rectification pushes efficiency to 95% with only 50mV ripple, while an onboard smart chip adds over-current, over-load, low-load, short-circuit, over-heat and anti-reverse protection. A built-in fuse provides additional safeguard for connected devices.

Questions about this item

What comes in the box and do I need to buy any cables or fuses separately?

The unit ships as a complete converter with an anti-reverse fuse already fitted inside its aluminium housing; no extra cables or fuses are required for basic installation.

Should I choose the 36 V or 48 V input version for my golf cart?

A single model accepts a 30 V to 60 V range, so it works with both nominal 36 V and 48 V battery packs without any version selection.

What does the 120 W rating mean when the converter is running on my cart?

It can deliver a continuous 12 V at 10 A (120 W) with up to 95 % efficiency, 50 mV ripple and a 2-second start delay, operating reliably from -40 °C to 80 °C.
