BFKK adjustable DC power supply, 2.8 inch IPS display, compact bench form, matte dark finish

BFKK

BFKK 0-30 V 5 A Adjustable DC Power Supply with 2.8" IPS Display

SKU CH-717W-56QV0

Adjustable 0-30 V, 0-5 A DC supply with 150 W output, <20 mV ripple, 2.8" IPS display and PC programmable presets

  • High-precision 0.01 V / 0.001 A readout protects sensitive circuits
  • 150 W adjustable output covers 0-30 V and 0-5 A
  • 8" IPS display flips 90° for multi-angle viewing
  • Eight built-in protections guard against over-voltage, over-current, short-circuit and overheat

Purpose & Audience

The BFKK adjustable DC power supply delivers 0 to 30 V at up to 5 A for bench testing, prototype powering and repair work. Its 150 W maximum output suits engineers, hobbyists and students who need precise, programmable voltage and current for low-power circuits.

Build & Connections

A 2.8 inch IPS colour screen flips 90° for comfortable viewing at any angle and shows both numeric read-outs and real-time curves. The unit offers 4 mm banana sockets, U-shaped terminals and fine copper wires so you can hook up development boards, bare leads or screw-terminal loads without adapters.

Extras & Software

Six preset slots store voltage and current combinations for instant recall, and PC programmability lets you script automated test sequences. The bundle includes two charging-head variants shipped at random, while the manual advises adding a Schottky diode on the output when charging batteries to block reverse current.

Questions about this item

What is the maximum voltage and current the 0-30 V 5 A supply can deliver, and what resolution does the IPS display show?

The unit delivers up to 30 V and 5 A with a 150 W limit, and the 2.8-inch IPS display shows 0.01 V and 0.001 A resolution.

What physical connection types are provided on the output terminals?

The output side includes 4 mm banana sockets, U-shaped terminals and fine copper wire terminals for different lead styles.

How do you program the six preset output groups from a PC, and what mistake do users often make when charging batteries?

Connect the supply via its PC programmable interface, use the supplied software to store six voltage and current sets, and always add a reverse-current protection module such as a Schottky diode when charging batteries.
