240W Waterproof Step-Down Converter

This GCON DC-DC converter steps 24V, 36V or 48V inputs down to a regulated 12V output at up to 20A and 240W. Its aluminium housing uses silicone sealing to achieve a 100% waterproof, dustproof and shockproof rating for harsh environments. Built-in protections cover input undervoltage, overload, overcurrent, overheat and output short-circuit conditions. Typical uses include automotive trucks, golf carts, LED strips, screens, surveillance systems, motors and DIY projects.

Suits 12V loads up to 20A from 20V-60V sources

Installers powering 12V accessories from higher-voltage vehicle or cart batteries will find the wide input range and rugged sealing a direct fit. The unit lacks adjustable output voltage, so systems needing anything other than fixed 12V should look elsewhere. Buyers who require galvanic isolation or a step-up topology are not served by this buck-only design. Applications demanding more than 240W continuous power exceed the converter's rated headroom.

240W continuous capacity with 20A peak

The converter comfortably runs 12V loads such as LED lighting, surveillance cameras or small motors up to the full 20A rating when adequately cooled by its case. Operation at the 60V input maximum increases internal dissipation, so sustained full-load use at the top of the input range may trigger thermal protection. Loads drawing significantly above 20A or requiring surge currents beyond the built-in overcurrent threshold will cause the unit to shut down.

Questions about this item

What input voltage source do I need to power this 240 W step-down converter?

Connect a DC supply between 20 V and 60 V — rated for 24 V, 36 V or 48 V systems — to the converter's input terminals.

Can I keep my existing 12 V accessories when installing this reducer in a 48 V golf cart?

Yes, the converter outputs a steady 12 V at up to 20 A, so your current 12 V lights, screens or motors can stay connected.

How do I verify the unit is regulating correctly after wiring it?

Measure the output with a multimeter under load; it should read 12 V while the aluminum shell remains cool and no protection fault triggers.
