Input range and output power

This KEHIPI buck-boost adapter accepts a wide 8 V to 40 V DC input and delivers a regulated 12 V output at up to 6 A, providing 72 W of continuous power. It suits golf-cart owners, club-car operators and anyone needing stable 12 V from variable battery banks.

Wiring and voltage checks

Verify that your source stays within the 8 V to 40 V window and can supply up to 10 A input current. Confirm the load draws no more than 6 A at 12 V and that polarity matches the marked terminals before connecting.

Thermal and protection behaviour

The aluminium epoxy-potted shell is rated IP68 and operates from -40 °C to 80 °C with 95 % peak efficiency and 50 mV ripple. Built-in smart-chip protection covers over-current, over-load, low-load, short-circuit and over-temperature events.

Questions about this item

What comes in the package and what must be purchased separately?

The package includes one DC voltage converter module rated for 8V-40V input and 12V 6A 72W output. Input wiring, output wiring, fuses and mounting hardware are not included and must be sourced separately.

How do I decide between the 12V, 24V and 36V nominal input versions?

This single unit accepts the full 8V-40V range, so it covers 12V, 24V and 36V nominal systems without needing different versions. Choose it when your source voltage falls anywhere within that range.

What does the 72W rating mean when the converter is installed in a vehicle?

It means the module can continuously supply 12V at up to 6A (72W) to your load, with 95% peak efficiency and 50mV ripple, provided the input source can deliver the required current up to 10A.
