SUGON 3005D DC Power Supply

Not every bench needs programming or a computer link. The SUGON 3005D is a manual 30V 5A supply with knobs for voltage and current, and that simplicity is part of its appeal.

The 3005D from SUGON provides 0 to 30V and 0 to 5A with fine adjustment, an LED display showing voltage, current and power, constant-voltage and constant-current modes and protection against overvoltage, overcurrent, short circuits and overheating. It has a metal case and a built-in cooling fan.

When the 3005D fits

• Phone and tablet board testing.

• Finding shorts by limiting current.

• Powering circuits during soldering and testing.

• Replacing a worn or failed supply.

Plug and setup

Pick EU or UK plug for 220V outlets, or US plug for 110V. Place it where the ventilation slots stay clear.

The listing's advice is sound: start at the lowest settings and raise them gradually, and set the protection limits before connecting a board. If you need saved presets or logging, the 3005PM adds those. Keep the output leads short and check the clips for corrosion now and then, since a worn lead can drop voltage before it reaches the board.
