BFKK 110V/220V AC to 12V DC 600W 50A Converter Power Supply

SKU CH-P11D-MK3B7

Converts 110V or 220V AC to 12V DC with 50A peak current and automatic overload, over-voltage, thermal and short-circuit protection

  • Handles 110 V and 220 V input for worldwide use
  • Delivers up to 50 A peak current for high-draw loads
  • Automatic overload, over-voltage, thermal and short-circuit protection built in
  • Supports equipment up to 40 A continuous for reliable operation
  • Includes UL power cord, wire lugs, metal clip and screws for easy wiring

What this converter does and who needs it

This AC-to-DC converter supplies 12 V power from a 110 V or 220 V mains input. It is intended for users running DC 12 V equipment such as pumps, LED strips, car audio amplifiers, winches, or automation gear. The unit delivers a peak of 50 A and 600 W, with a recommended continuous load below 40 A and 480 W. It is not suitable for PWM motors, adjustable-speed motors, dimming lights, plant lights or DC power controllers.

The specification that decides fit

The critical figure is the 50 A peak current and 600 W peak power rating. Your connected load must stay under 40 A or 480 W for normal operation. Resistive devices require the supply peak power to be 1.25 times the device rating. Motor-driven devices need the supply peak power to exceed twice the motor rating. Input accepts 85–145 V AC or 185–265 V AC.

Installation notes and common pitfalls

A red on/off switch provides simple power control. The built-in wiring design offers dual connection methods with supplied wire lugs, a metal clip, screws and a UL power cord. Set the selector to the correct gear position before use. Always cut power before disconnecting wires. Protection includes automatic overload, over-voltage, thermal cut-off and short-circuit safeguards.

Questions about this item

What does the 600 W peak rating mean when I connect my equipment?

The unit can deliver 600 W for short bursts; continuous loads should stay at or below 480 W (40 A) and resistive devices need the supply rated at 1.25× the load while motor loads need more than 2× the motor power.

How does the AC input range of 85–265 V affect which mains I can use?

The auto-ranging input accepts 110 V (85–145 V) and 220 V (185–265 V) mains without manual switching, so it works on standard household supplies worldwide.

What mounting hardware is included so I can secure the supply?

The package supplies metal clips and screws for panel mounting, plus wire lugs and a UL power cord for wiring connections.
