Voltage step-down for golf carts and 12 V systems

This KEHIPI buck converter accepts a DC input between 18 V and 60 V and delivers a regulated 12 V output at up to 20 A, providing 240 W of continuous power. It is suited to golf carts, industrial vehicles and other equipment that runs from 24 V, 36 V or 48 V batteries but needs 12 V accessories.

Synchronous rectification holds 95 % efficiency

The module uses synchronous rectification to keep conversion efficiency at 95 % with only 50 mV ripple, and a two-second soft-start limits inrush current. Over-current, overload, low-load, short-circuit and over-temperature protections are handled by an onboard smart chip, while the aluminium shell and epoxy potting dissipate heat across a -40 °C to 80 °C operating range.

Verify your source voltage

Ensure the supply stays within the 18 V to 60 V window and can provide enough current for the 240 W output. The unit measures 2.9 in by 2.9 in by 1.22 in and weighs 248 g, so confirm mounting space and use the supplied quick-connect terminals for a secure, waterproof connection.

Questions about this item

How much heat does the 240W converter produce when running at 20A all day?

The synchronous rectification design reaches 95% efficiency with only 50mV ripple, so waste heat stays low and the aluminium shell with epoxy potting dissipates it without a fan.

What wiring must I already have to connect this unit?

You need a DC source between 18V and 60V and two quick-connect terminals for the 12V 20A output; the built-in anti-reverse fuse holder protects the input side.

Will the converter survive vibration and temperature swings in an older golf cart?

The IP68 potted module is rated for -40°C to 80°C and the aluminium casing resists shock, dust and water, making it suited to harsh vehicle environments.
