SKU CH-J8N9-FNAJK

Steps down 8-40 V input to 12 V at 10 A with 120 W output, 95 % efficiency, and IP68 protection

  • Wide 8V-40V input fits many vehicles
  • Stable 12V 10A output powers accessories reliably
  • 120W capacity with 95% efficiency reduces energy waste
  • IP68 sealed aluminium housing resists water, dust and shock
  • Six smart-chip protections guard against overload, short-circuit and overheating

DC step-down converter for 12 V systems

This DC-DC step-down converter accepts an input range of 8 V to 40 V and delivers a regulated 12 V output at up to 10 A for a maximum of 120 W. It suits golf carts, club cars, trucks and other mobile equipment that need stable 12 V power from a higher-voltage battery bank. The module is built for DIY projects, vehicle accessories and fixed installations alike.

IP68 sealed aluminium housing

Synchronous rectification technology pushes conversion efficiency up to 95 %, reducing waste heat during normal operation. The aluminium shell is silicone-sealed to achieve an IP68 rating, making the unit waterproof, dust-proof, anti-shock and resistant to humidity. Integrated smart-chip protection guards against over-load, over-current, over-temperature, short-circuit and over-voltage events.

Compact rugged module for permanent mounting

The sealed aluminium enclosure doubles as a heatsink, allowing the converter to run continuously without external cooling in typical vehicle environments. Its rugged construction tolerates vibration and exposure to the elements, so it can be bolted directly to a chassis or bulkhead. Wiring connects to the input and output terminals for straightforward integration into 12 V lighting, audio, monitoring or accessory circuits.

Questions about this item

How do I wire the DC 8V-40V input to my golf cart battery, and what polarity mistake causes immediate failure?

Connect the input leads to the 8V-40V source with correct positive and negative polarity; reversing them triggers the over-voltage protection and can damage the smart chip.

What maintenance does the IP68 sealed aluminum housing need after months of dust and water exposure?

The silicone-sealed case is maintenance-free; just rinse off mud or salt spray and verify the mounting bolts stay tight for heat dissipation.

At what load does the 95 % efficiency converter hit its thermal limit during continuous operation?

Sustained 10 A output at 12 V (120 W) will activate over-temperature protection first, so derate or add airflow for long runs.
