Precision encoder adjustment

The Wanptek GA3010 is a bench-top DC power supply built for engineers, technicians and hobbyists who need repeatable voltage and current settings. A precision encoder knob replaces a traditional potentiometer so values can be entered directly digit by digit. The unit delivers up to 32 V and 10 A from a compact plastic enclosure.

Upgrade from potentiometer supplies

It replaces older bench units that rely on coarse and fine potentiometers which can drift and are slow to set to an exact figure. The encoder lets you press to select the digit then rotate to change it, making the jump worthwhile when you frequently dial in specific test points such as 0.1 V or 0.001 A steps. A built-in USB fast-charge port with live output display adds convenience for powering phones or prototype boards without a separate charger.

Check your bench requirements

Verify that 32 V and 10 A cover the maximum voltage and current your circuits will draw. Confirm the 7.48 in by 3.15 in by 5.71 in footprint fits your available bench space and that a single output channel is sufficient for your typical workloads. The supply includes short-circuit, overload and thermal protection with a temperature-regulated fan, so ensure ambient ventilation is adequate for continuous operation.

Questions about this item

What bench space does the 7.48 in x 3.15 in x 5.71 in chassis need?

The unit measures 7.48 in wide, 3.15 in deep and 5.71 in high, so allow at least that footprint plus clearance for the rear fan and front USB ports.

How do I set a precise voltage using the encoder knobs, and what step do users often skip?

Press the voltage knob to select which digit to change, rotate to set 0-32 V in 0.1 V steps, then press the output control switch to enable — forgetting to enable output is the common mistake.

When should the internal temperature-regulated fan be cleaned or replaced?

Clean the fan intake when dust builds up; replace the fan if it becomes noisy or fails to spin, since it protects the 10 A output circuitry from overheating.
