(Instructions for Purchase)

150W 200V 20A Capacity Tester Adjustable Constant Current Digital Electronic Load

For Battery of Coulombmeter Voltmeter Power Meter Ammeter

functional descript

Must read brief introduction:


can test all kinds of batteries, all kinds of DC power supply, all kinds of data cables,

a variety of charge bank, all kinds of chargers,

Voltage, current, power, capacity, power quantity,

discharge time, internal resistance and load capacity of various AC / DC power supply adapters

Performance, function comparable to the thousand yuan electronic load instrument is more,

and the volume is also relative, flexible use, mainly has the cost advantage,

Very suitable for manufacturers of verification, digital enthusiasts,

engineers and other experiments of instruments.



When entering the high-voltage battery and the large power supply test,

Two current knobs must be adjusted counterclockwise to zero before access use,

Then, the current knob is slowly adjusted according to the display current power,

Must not instantly adjust big tune full,

so that the instant power is too large to cause a huge loss of load burning discharge pipe!

Please pay special attention to this point, thank you!

Because of the operation problems,

burning, damage,our company,no, bear, responsibility!!!
