Function Introduction:

a. Protection function:

OVP (over-voltage protection): there is OVP at 25-30V; it will be damaged permanently over 30V.at OVP, LED show OVP, as ture 1 show)

OTP(over-temperature protection): load temperature is over  80℃, the LED show OTP, as ture 2 show.

OPP(over-power protection): the power is over  80℃, the LED show OPP, as ture 3 show.

b. Set output recovery mode after load entering protection status, manual or automatic

c. View the voltage value, current value and power value of the load.

d. Intelligent temperature control fan. When the current is over 2A or the temperature is over 40℃, the fan will start.

e. Precision multiloop adjustable potentiometer: you can adjust the current precisely, upto 0.01A. so you don’t need to adjust a big current mistakenly to damage the power supply. So the power supply will not be damaged due to mistakenly adjustment

f. you can set default boot status freely, open or close.

Trigger /DecoyFunction: 1. Trigger function: The charger can be used for QC2.0, QC3.0, Huawei FCP, Samsung AFC 9V and multle fast charging modes for trigger. 2. Quick charge support detection function: Use the AUTO mode to detect that the charger can support for fast charge mode or not. 3. Power-on automatic trigger function: After power on, trigger automatically quick charge and automatically turn on the load, which is suitable for batch testing for chargers.

Operation Instruction

The load is powered at the range of 4-25.0V (the input polarity cannot be red, otherwise the product is permanently damaged and cannot be repaired), the LED will be fing to remind current setting value, waiting for output. Pre ON/OFF on, open output to start work.

1. Adjust output current value.

Turning the rotary control clockwise increases the value and anticlockwise decreases the value. According to the needs of the situation, the potentiometer can realize coarse adjustment or fine adjustment. The fine adjustment can be accurate to 0.01A.

2, Adjust LED display statu

Pre “SET” to adjust the LED display status, default display output current value. Pre “SET” on to display *.**A、**.*P、**.*V followed by recycling.

3. Open or close load output

Pre “ON/OFF” on, you can open or close load output

4, Set load default boot status (open or close status, Factory default close status)

Pre and hold “ON/OFF” on to set load default boot status freely. Pre and hold “ON/OFF” on, if the LED will display “--ON”, as ture 4, the load will open output when power on next time; If the LED display”-OFF”, as ture 5 show, the LED will display current value fing at last shutdown when power on next time, then pre “ON/OFF” on to open output.

5, Set the load output recovery mode after protection removed.

Pre and hold “SET” on, to set output recovery mode after protection removed. Pre and hold “SET” on, if the LED will display “--ON”, as ture 4, and the protection was removed, the load will recover to work; If the LED display”-OFF”, as ture 5 show, and the protection was removed, the LED still show protection status, then pre “ON/OFF ‘on, the display will display present setting current fing, then pre “ON/OFF‘ on again, the load recover to work.

NOTE: Please check the output current of carefully. The current of the general is generally small, so adjust smaller current when the load was used.

Trigger function introduction:

The trigger/decoy function is the function of sending signals on D+D- to induce quick charging of the charger. Under this mode, the load cannot be switched on and off. But the current of the load can still be adjusted by the potentiometer. (except AUTO mode, other modes only send trigger instructions and do not judge whether the trigger is succeful or not)

The mode corresponding to different display states in the trigger mode:

QC2.0 5V: LED tube displays -05.0, red LED indicator fing

QC3.0: LED tube displays actual voltage, green LED indicator fing

Samsung AFC9V: LED tube displays AFC9, blue LED indicator fing

Huawei FCP: LED tube displays FCP9, blue LED indicator fing

AUTO: LED tube displays AUTO

on function at trigger function:

SET/- on:

Short pre: begin to trigger or switch the voltage of current quick charge mode

Long pre: record current quick charge state, and open or close auto trigger function

OK/+ on:

Short pre: begin to trigger or switch the voltage of current quick charge mode

Trigger on:

Short pre: switch trigger mode

Long pre: switch to load mode

1, Entry/exit trigger mode

Long pre the trigger on to switch between trigger mode and load mode, when trigger mode enters into the load mode, the trigger state stay.

2, Mode switch:

Short pre the trigger on to switch between 4 modes, QC2.0, QC3.0, FCP/AFC and AUTO, In the same time, the LED indicator will light. When you switch mode, last mode trigger state will be closed.

3, QC2.0 trigger:

At QC2.0 mode, pre OK on, after 2s corresponding LED will fing to remind trigger complete, pre + or – on to switch between QC2.0 5V, 9V, 12V and 20V，long pre to apply the QC mode.

4, QC3.0 trigger:

At QC3.0 mode, trigger operation is same with above. LED display the real voltage, pre + or – on to increase or decrease voltage value, long pre to apply the QC mode

5, FCP/AFC trigger:

At FCP/AFC mode, trigger operation is same with above. Pre + or – on to switch between FCP and APC, long pre to apply the QC mode

.

6, AUTO trigger:

AUTO mode is used to detect the charger's support for the quick charging protocol. Short pre "OK" on in AUTO mode for automatic load detection, and wait patiently for about 25 seconds, the LED indicates the quick charging protocol supported by the charger

7, Power on auto trigger:

Power on auto trigger can be used for batch chargers, automatically trigger preset mode after loading.

Set the load current and the boot automatically output of the load, adjust to the need of quick charge mode, and then long pre SET on, the preset is done. Long pre SET on again to turn off auto trigger (QC3.0 can only remember positive bias value).

Q&A

Q: My charger nominal maximum support QC2.0 12V2A, how do I test if the charger is supported?

A: Insert load, long pre the trigger on, then short pre "OK" on, after the red light fing, then short pre twice to switch to QC2.0 12 v mode. Long pre the trigger on to enter the load mode, and pre the SET key to check whether the current voltage is around 12V. Turn on the load and slowly adjust the current to 2A. Check the voltage to see if there is a significant drop (> 0.5v), then let the load work for a while and measure the heating of the charging head. If the load is restarted or the voltage has a significant drop or the charging head has a sharp heating, the charging can not be fully loaded and must be used with reduced load.

Q: is my PD2.0 charger supported?

A: load can PD charger, but not trigger PD charger . Double head type-c line is connected with PD charger and load, and PD charger output 5V by default. If PD charger supports QC2.0 at the same time, high voltage can be achieved by trigger QC2.0.

Q: how do I get out of the trigger quick charge?

A: At trigger mode, short pre trigger on to switch mode to exit; at load mode, long pre the trigger on to enter the trigger mode and exit automatically.

Application
