Rectangular aluminium module with epoxy potting, waterproof, input 8V-40V output 12V 3A

LORDWORLD

LORDWORLD DC 8V-40V to 12V 3A 36W Step Down Up Regulator Waterproof Module

SKU CH-3V34-Q403D

Converts 8-40 V DC to a stable 12 V 3 A supply with 95 % efficiency, full waterproofing and built-in protection for golf carts and vehicles

  • Wide 8V-40V input fits 12V/24V/36V systems
  • 95% peak efficiency reduces heat and power loss
  • Smart chip guards against over-current, overload and short-circuit
  • Fully potted aluminium case rated 100% waterproof and dust-proof
  • Operates reliably from -40°C to 80°C

Input Range and Application

This DC-to-DC converter accepts a wide 8V to 40V input and delivers a stable 12V output at up to 3A. It suits golf-cart owners and mobile-equipment operators who need reliable 12V power from 12V, 24V or 36V nominal battery systems.

Buck-Boost Topology Limits

The synchronous rectification design achieves up to 95 percent efficiency with 50mV ripple and a two-second start delay. It cannot supply more than 36W continuous, so loads exceeding 3A will trigger over-current protection and shut the unit down.

Power Headroom and Environment

At 36W the module comfortably runs lighting, gauges and small accessories in a sealed aluminium housing rated for -40°C to 80°C. It runs out of headroom for high-draw motors or multiple amplifiers, which demand a higher-wattage supply.

Questions about this item

Which input voltage range suits a 24 V golf cart battery?

The module accepts 8 V to 40 V, so a 24 V nominal system stays well within the supported window.

What does the 36 W rating mean for connected accessories?

It delivers up to 3 A at 12 V, powering lights, radios or GPS units that draw 36 W or less.

How does the DC-DC converter interface with the vehicle wiring?

It connects directly across the battery leads; the buck-boost topology regulates 12 V output whether the input is below or above 12 V.
