  • Smart fan cools quietly during 150 W continuous load
  • Over-voltage, over-current and low-voltage alarms protect the module

USB Load Tester Module

The WUQ USB Load Tester is a plug-in module designed for engineers and hobbyists who need to characterise DC power sources. It measures voltage, current, power, capacity, impedance, temperature, energy and time in a single device. Buyers who require wireless logging or automated sequence scripting will not find those functions here.

Thermal and Power Behaviour

A built-in CPU fan and smart fan arrangement dissipate heat effectively and quietly during operation. The unit handles a maximum load of 150 W at up to 200 V and 20 A. Over-voltage, over-current and over-power alarms protect the module from damage during extended test runs.

Measurement Range Decides Suitability

Voltage is measured from 0.00 V to 200 V with 0.01 V resolution. Current spans 0.00 A to 20 A with 0.01 A resolution. The refresh interval exceeds 500 ms, yielding roughly 0.5 readings per second. Alarm thresholds are programmable from 1 V to 200 V for over-voltage, 0 V to 190 V for low-voltage and 0.2 A to 100 A for over-current.

Questions about this item

How do I connect the USB Load Tester to a battery for a capacity test?

Connect the battery to the input terminals, set the desired discharge current up to 20 A, then start the test; the LCD shows voltage, current, capacity and elapsed time.

What part will need attention after many hours of high-power discharge?

The CPU fan provides active cooling; dust build-up on the fan and heatsink should be cleaned periodically to maintain airflow.

At what power level does the over-power protection activate during a long test?

The unit triggers an alarm and stops the load when power reaches 150 W.
