Functions:

1.Load function / protection function / OVP over voltage protection:

25V-30V over-voltage protection, it will be permanently damaged after over 30V; after over-voltage protection, the output will be automatically cut off, and the digital tube will display OVP.

OTP over temperature protection: the load temperature is greater than 80 degC, the output is automatically cut off, and the digital tube displays OTP.

OPP over power protection: power greater than 25W or 35W, automatic cut off output, digital tube display OPP

Set the load to return to normal operation manually or automatically after releasing the protection condition. Check the load voltage value, current value, and power value.

2.Intelligent temperature control fan:

The fan starts automatically when the power consumption is greater than 10W or the load temperature is greater than 40°C.

The precision multi-turn adjustable potentiometer can adjust the current to 0.01A accurately, and it will not damage the power supply due to excessive current error caused by hand error.

Freely set the load power on state to power on or off.

3.Trigger/cheat function Trigger function:

The charger can be QC2.0, QC3.0, Huawei FCP, Samsung AFC 9V, and multiple fast charging modes for deception triggering.

4.Fast charge support detection function:

Use the AUTO mode to detect the charger\'s support for fast charge mode.

5.Power-on automatic trigger function:

Power-on automatically triggers fast charge and automatically turns on the load, which is suitable for batch testing of aging chargers.

Operating Guide

1.Load function Power on the load in the range of 4-25.0V (Note: the input polarity cannot be reversed, otherwise it will be permanently damaged and cannot be repaired). The load digital tube flashes to remind the current setting value. Short press the "OK" button to start the load.

2.Adjust the output current. Rotate the potentiometer to adjust the current. Rotate the clock clockwise to increase the data. Counterclockwise, the counterclockwise can be accurate to 0.01A.

3.Adjust the display status of the digital tube. Press the "SET" button to switch the display status of the digital tube. The output current data is displayed by default. Press the SET button to select the current current: *.**A; current power: **.*P; current The voltage **.*V is displayed cyclically.

4.Turning the load output on or off Short press the \"OK\" button to turn the load output on or off.

Set the load status at power on (open or close the output, the factory default off state) Press and hold the \"OK\" button to freely set the load boot output status.

5.Press and hold the \"OK\" button. If the digital tube displays \"--ON\", as shown in the figure, the load will automatically open the output when the next power is turned on; if you press the \"OK\" button long, the digital tube displays \"-OFF\", then under When the power is turned on, the load digital tube will flash to remind the current value when the power was turned off. Short press the "OK" button to open the output (this setting is related to the automatic trigger setting).

6.Set the load to restore the recovery mode in the protected state. Press and hold the "SET" button to adjust the recovery mode after the load release protection. Press and hold the "SET" button. If the digital tube displays "--ON", the load will automatically resume normal operation after the protection condition is released in the protection state; long press the "SET" button, if the digital tube displays "-OFF", After the protection condition is released, the digital tube still displays the protection status. Short press the "OK" button to flash to remind the current setting current, then press the "OK" button to resume normal operation.

Note: Please carefully check the nominal output current of the charger. The common charger current is generally small. Please be careful not to exceed the rated value when using the load.
