BFKK DC Power Supply Variable White video accessory

Bench supply with 0.001 A resolution

The BFKK DC Power Supply Variable White is a benchtop switching regulated unit that delivers adjustable output from 0 to 120 V and 0 to 3 A. A backlit 4-digit LED display shows voltage and current with a resolution of 0.001 A for precise monitoring. Coarse and fine adjustment knobs let operators dial in exact settings while automatic constant-voltage and constant-current mode switching handles load changes without manual intervention. Built-in protections include grounding, leakage, thermal, voltage overload, power overload and short-circuit safeguards.

For labs, education and DIY repair

Technicians, students and hobbyists who need a compact bench source for circuit testing, electrolyzation, electroplating, battery charging or lamp ageing will appreciate the lightweight form factor of 9.5 x 3.4 x 6.1 inches and integrated 5 V 2 A USB port. The intelligent fan activates only when the internal temperature exceeds 50 °C, keeping acoustic noise low during light loads. Users requiring higher current capacity, multi-channel output or programmable remote control should consider a different class of supply.

0.001 A display resolution drives selection

The defining specification is the 0.001 A current resolution on the 4-digit LED readout, which determines whether the unit can verify low-current behaviour in sensitive circuits. If the application demands finer resolution or data-logging capability, this model will not meet the requirement. For general bench work where milliamp-level visibility is sufficient, the resolution matches the need.
