BFKK AC to DC Converter 12V 100A 1200W Power Supply

SKU CH-34BK-NQ2SR

Converts 110-240V AC to 12V DC with up to 100A and 1200W, featuring overload, over-current and short-circuit protection plus a built-in cooling fan for stable operation

  • 12 V DC output from 110–240 V AC input
  • Up to 100 A and 1200 W for demanding 12 V loads
  • Overload, over-current and short-circuit protection built in
  • Aluminium shell with cooling fan and multiple vents for heat dissipation
  • Nickel-plated copper terminals allow direct clamp connection

12 V 100 A Power Supply

This AC-to-DC converter delivers a regulated 12 V output with a maximum current of 100 A and a peak power of 1200 W. It accepts a wide 110-240 V AC input, making it suitable for global mains voltages. The unit targets installers and hobbyists powering 12 V loads such as LED strips, CCTV systems, 3D printers, RV appliances and car audio equipment.

Screw Terminals and Fan Cooling

Two nickel-plated copper terminals accept clamp connections for quick wiring without soldering. An internal cooling fan and a vented aluminium-alloy enclosure with multiple holes dissipate heat, while anti-skid pads improve airflow underneath. Overload, over-current and short-circuit protections shut the unit down automatically if a fault occurs.

Installers Needing High-Current 12 V

The supply suits anyone who needs a single 12 V rail up to 100 A for industrial automation, motor pumps, security cameras or lab projects. Buyers who require multiple output voltages, adjustable voltage settings or battery-backup functionality should look at a different product class.

Questions about this item

How do I confirm the converter is delivering the correct 12 V DC output after wiring it up?

Measure the voltage at the two nickel-plated copper terminals with a multimeter; it should read 12 V DC when the unit is powered and the cooling fan is running.

What comes in the box and do I need to buy any cables or clamps separately?

The supply includes the aluminium-housed unit with built-in cooling fan, anti-skid pads and two nickel-plated copper terminals for direct clamp connection; no extra cables or clamps are required.

Which current setting should I select for a load that draws about 480 W at 12 V?

Choose the 40 A / 480 W rating; the converter supports step ratings of 10 A/120 W, 20 A/240 W, 40 A/480 W, 50 A/600 W, 80 A/960 W and up to 100 A/1200 W max.
