Adjustable 0–30 V / 0–10 A lab supply

The BFKK LW-K3010D is a switching regulated DC power supply built for laboratory, educational and repair bench use. It delivers continuously adjustable output from 0 to 30 volts and 0 to 10 amperes with a backlit three-digit LED read-out showing voltage, current and power. Precision is rated at 0.1 V and 0.01 A, making it suitable for component testing, spectrophotometer work and general electronic prototyping.

Alligator leads and US cord included

The unit ships with output cables terminated in alligator clips and a US mains cord, so it can be connected to a device under test immediately. Complete test probes are also supplied, covering the typical hook-up needs of a school lab, home workshop or field repair kit without extra purchases.

Protection suite and fan cooling

Over-current, over-power, over-temperature and over-voltage safeguards are built in, plus a grounding wire for safe operation. An intelligent temperature-controlled fan and heat-radiation grooves on both sides manage thermal load, reducing acoustic noise while extending service life. The chassis measures 2.7 by 8.6 by 6.3 inches and weighs under 2 kg.

Questions about this item

How often does the intelligent temperature-controlled fan need cleaning to maintain airflow?

The fan runs only when the internal sensor detects heat, so dust buildup is slower than constant-running designs; a quick blast of compressed air every few months keeps the side radiation grooves clear.

Which protection circuit activates first during a long, high-current session — over-temperature or over-power?

Over-temperature protection engages first; the large fan and dual-side heat grooves are sized to delay that point, but sustained 10 A output will trip the thermal limit before the over-power threshold.

How loud is the fan and how hot does the case get when the unit runs at 30 V 10 A all day?

The temperature-controlled fan stays at low speed until the heatsink warms up, so noise stays near office-background level; the aluminium case reaches warm-but-touchable temperatures thanks to the side radiation grooves.
