DC bench supply for lab and repair

The WANPTEK DPS series is a new adjustable DC power supply rated at 25 W with a 0–30 V and 0–5 A output range. It accepts 125 VAC input and automatically switches between 115 V and 230 V ±10 % mains. Coarse and fine encoder knobs let you set voltage and current in two steps, while a four-digit display shows the values.

Suits hobbyists, students

The USB-A and USB-C ports deliver 5 V at 3.6 A for charging phones or powering USB devices under test. Over-current, over-voltage, over-temperature, short-circuit and leakage protections shut down output and sound an alarm when a fault occurs. Buyers who need more than 25 W or higher current should look at a larger unit.

25 W total power budget decides fit

The supply provides up to 30 V at 5 A but cannot exceed 25 W continuous, so the maximum current drops as voltage rises. Verify that your circuit stays within this envelope before purchasing.

Questions about this item

What bench space does the 13.589 cm x 19.5072 cm x 26.4922 cm unit need?

The supply measures 13.589 cm wide, 19.5072 cm deep and 26.4922 cm high, so allow that footprint plus a few centimetres for cable bend radius and ventilation.

How do I set a precise voltage with the coarse and fine encoder knobs?

Turn the coarse knob to set the whole-volt digit, then turn the fine knob to dial in the decimal places; the four-digit display shows the result in real time.

When should I expect to replace the internal cooling fan?

The fan is rated for continuous operation at the 25 W design load; under normal bench use it typically lasts several years before bearing noise signals a swap.
