Load function Detail

First, perfect protection mechanism

1. Load voltage has anti-reverse protection, reverse connection does not burn;

2. OVP Overvoltage Protection (default 25.2V, can be set itself, after Overvoltage protection, LCD interface flashing display OVP);

3. OCP Overcurrent Protection (default 4.10A/5.10A, can be set itself, after overcurrent protection, LCD flashing display OCP)；

4. OPP Over power protection (default 25.5W/35.5W, can be set itself, after power protection, LCD flashing display OPP);

5. OTP Over-temperature protection (after the load temperature is greater than 80 ℃, over-temperature protection, liquid crystal flicker display OTP);

6. LVP Undervoltage Protection (default 4.0V, can be set itself, after Undervoltage protection LCD flashing display LVP, In applications such as battery discharge testing, the setting of suitable LVP can effectively prevent the battery from transitioning to discharge, so as not to damage the battery).

Second, the electronic load on the initial state of power:

The electronic load automatically saves the switching state before shutting down and acts as the initial state of the next power-on;

Third, discharge capacity and discharge time statistics:

1. Discharge capacity statistics: Starting from the open load statistics, until the next load disconnect thought to complete a discharge process, statistical end;

2. Discharge time Statistics: Starting from the open load statistics, until the next load disconnect thought to complete a discharge process, statistical end;

Four, set the maximum capacity (OAH) and set the maximum discharge time (OHP):

1. Set maximum Capacity (OAH): When the OAH function is started, when the load discharge capacity is higher than the maximum capacity set, the electronic load stops automatically and flashes to display "OAH", and when the OAH alarm is lifted, the capacity statistics are automatically emptied;

2. Set the maximum discharge time (OHP): When the OHP function is started, when the load running time is greater than the maximum discharge time set, the electronic load stops automatically and flashes to display "OHP", and when OHP alarm is lifted, the time statistics are automatically emptied;   

Note: When the OAP and OHP functions are not turned on, the electronic load will record the discharge capacity and discharge time, When the OAH and OHP functions are turned on, the electronic load stops working after the set value; When the OHP function is turned on, the running time of the electronic load is the countdown mode;

   OAP and OHP functions, can be a good implementation of unattended power aging testing.

V. Data set Features:

Divided into "DAT0", "DAT1"

DAT0: Flashing only shows the capacity value and running time of the previous stage, and does not add up to the next stage;

DAT1: Flashing shows the capacity value and running time of the previous stage, and automatically accumulates to the next stage;

Vi. set the load to manually or automatically return to normal operation after the release of the protection mechanism (REC function)

Set the REC:ON state, the load automatically returns to normal work after the contact protection mechanism, and the REC:OFF state, the load needs to be manually returned to normal work after the release of the protection mechanism.

Seven, set power on whether to automatically trigger the fast charge function (AUTO function)

Set the AUTO:ON, power on the automatic trigger fast charge, suitable for batch test aging charger; AUTO:OFF, power on does not trigger fast charge.

Load function Interface Operation Description:

First, the operation interface operation instructions:

1. The electronic load is powered on and then enters the operating interface, which is used to turn the electronic load on or off by short pressing the "ON/OFF" button, and to modify the current of the electronic load in real time by rotating the encoder potentiometer;

2. Short press the encoding potentiometer key to toggle the downlink display content (current/power/capacity/time);

3. In any display interface, the rotating encoding potentiometer will automatically switch to the current display interface;

4. In the current display interface, the long press "ON/OFF" button is used to turn the data lock function on or off, if the data lock function is turned on, the locking symbol "|-" will be displayed in front of the current, at this time can not adjust the load current in real time by rotating the encoding potentiometer to prevent misoperation;

5. In the Capacity/Time interface, Long press the "ON/OFF" button to empty the corresponding capacity/time data.

Second, the Setup interface operation instructions:

1. In the running interface, the long press encoding potentiometer enters the setup interface;

2. By rotating the encoder potentiometer, adjust the size of the parameters, increase clockwise, and decrease counterclockwise; switch the parameters that need to be modified by short pressing the rotary encoder;

3. In the maximum capacity (OAH)/Maximum discharge time (OHP) interface, short press "On/off" button to select the corresponding function of the turn on or off, if closed, the display "----";

4. In the maximum capacity (OAH) interface, Long press the "ON/OFF" button to select the capacity range (9.999Ah/99.99 Ah /999.9 Ah /9999 Ah);

5. Parameter settings complete, long press encoder potentiometer, exit the Setup interface, set parameters automatically saved;

Trigger/Trick function

1.Trigger function:

  The charger can be QC2.0, QC3.0, Samsung AFC 9V, Huawei FCP, a variety of fast charging mode for decoy trigger.

  Power-on automatic trigger fast charge (set in AUTO:ON state), suitable for batch testing aging charger when used.

First, the trigger/Decoy function Description:

   The trigger/Decoy feature is the ability to send a signal on the D+ D- to induce the charger to charge quickly, and the load shuts down automatically after entering this mode. Trigger/Return to the switch state before the load when the trigger is complete. (with the exception of automatic detection, other modes send only trigger instructions and do not determine whether success is triggered)

Second, the trigger/Decoy function Interface Operation Description:

   1. First determine which kind of fast charge the charger supports;

     If you are unsure, you can detect the support of the charger for the fast charge mode by pressing the TRG trigger button.

     After the long press trigger button TRG, the liquid crystal downlink flashes dynamically to show ' 2. ' 3. ' A. ' F ', in the flashing process is the corresponding QC2.0,Q C3.0,AFC,FCP Fast Charge protocol detection, After the detection is completed, the charger supports the protocol will show ' 2.3.A.F ' on the LCD downlink, which supports which corresponds to which the corresponding display; short press the Encoding potentiometer button back to the load interface;   2. After determining the fast charge protocol supported by the charger, short press the trigger button TRG, enter the trigger Protocol selection interface (if you do not want to trigger the fast charge, you can short press the trigger button TRG return to the Load interface), By rotating the encoding potentiometer, select the Protocol (QC2.0,QC3.0,AFC,FCP) to be triggered, After selecting short Press encoding potentiometer button, enter the trigger of the protocol, the liquid crystal will dynamically display "----", after the trigger is completed, the corresponding display voltage will be as follows:

QC2.0 mode:

   The LCD downlink will show '-05.0 ', which can be selected by rotating the encoding potentiometer to '-09.0 ', '-12.0 ', '-20.0 ', Representing the 5.0v,9.0v,12.0v,20.0v of the QC2.0 protocol, the LCD uplink will display the real-time voltage, select the voltage file to be triggered and then short press the Rotary Encoder button, back to the load interface;

QC3.0 mode:

   LCD downlink will show '-05.0 ', can be rotated encoding potentiometer to increase or decrease 0.2V, LCD uplink will display real-time voltage, select the voltage file to be triggered after short press the Rotary Encoder button, back to the load interface;
