Compact Bench Supply for Makers

The BFKK SPS-X is a new adjustable DC power supply that delivers 0-30V and 0-10A from a desktop unit. It suits hobbyists, students and technicians who need a regulated bench source for Arduino, Raspberry Pi or general circuit prototyping. Dual USB-A and USB-C ports provide 20W fast charging for mobile devices alongside the main terminals.

Upgrade from Fixed Wall Adapters

This unit replaces fixed-voltage wall warts and basic linear supplies when you need variable output with 0.01V and 0.001A display resolution. The jump is worth it for projects that demand precise voltage sweeps, current limiting or simultaneous device charging and circuit power. It is not for buyers who require higher current capacity or multi-channel output.

Plug In and Set Limits

Connect the switchable 110V or 220V AC input, set the desired over-current protection level and enable the output with a single button press. The encoder knob adjusts voltage and current without unloading the circuit. Common issues include forgetting to configure OCP before connecting sensitive loads and overlooking the fixed over-voltage protection threshold.

Questions about this item

What are the exact dimensions of this bench power supply so I can check my workbench space?

The unit measures 7.28 inches deep, 3.35 inches wide and 6.29 inches high, weighing about 2.5 lbs, making it compact for crowded benches.

How do I set the over-current protection limit before enabling the output?

Use the encoder knob to dial the desired current limit up to 10 A; the OCP value is settable, then press the output button to activate power.

Does the internal cooling fan run constantly or only when the unit gets hot?

A temperature-regulated fan spins up only when internal heat rises, keeping noise low during light loads and ramping up for heavy 30 V 10 A operation.
