  • Delivers stable 12 V 20 A 240 W output for 12 V accessories
  • 95 % conversion efficiency reduces heat and extends battery run-time
  • 40 V to 60 V input range suits 48 V nominal golf-cart systems

48V to 12V DC-DC converter for 12V accessories

This step-down buck converter accepts a nominal 48V input with a 40V to 60V range and delivers a regulated 12V output at up to 20A and 240W. It suits golf carts, industrial equipment, solar installations and other 48V systems that need reliable 12V power for accessories such as lighting, GPS units or audio equipment.

Sustained 240W output with 95% peak efficiency

The converter maintains a maximum efficiency of 95% and limits output ripple to 50mV during continuous operation. Built-in protection covers over-current, over-load, low-load, short-circuit and over-heat conditions, while the epoxy-potted aluminium shell provides 100% waterproof, anti-dust and anti-shock performance for consistent thermal management under load.

Verify your 48V source stays within 40V to 60V

Before ordering, confirm that your supply voltage never exceeds 60V or drops below 40V, and that the connected 12V devices draw no more than 20A combined. The unit includes a 2-second start-up delay, so allow for this in any sequencing logic. Ensure mounting provisions suit the compact potted housing.

Questions about this item

How much heat does the 95% efficient 48V to 12V converter produce when running 20A all day?

At 95% efficiency the unit wastes roughly 12W as heat, and the aluminium shell with epoxy potting dissipates it without a fan.

What 48V source and wiring must I already have to feed the 40V–60V input range?

You need a 48V nominal battery or supply capable of 20A plus cables and a fuse rated for the 40V–60V input window.

Will the 50mV ripple on the 12V 20A output disturb a vintage GPS or radio kept in the same golf cart?

The 50mV ripple is low enough for most legacy 12V accessories such as GPS units, speakers or LED displays.
