Feature Description:

1. The current a voltage V power W capacity ah and discharge time can be displayed;
2. Have a sound protection mechanism;
3. Automatic statistics of discharge capacity and discharge time;
4. Set maximum discharge Capacity OAH and maximum discharge time OHP; Realization of unattended experiments
5. ligent temperature-controlled fan, when the power is greater than 10W or the temperature is greater than 40 ℃ fan start automatically;
6. The use of rotary potentiometer, can accurately adjust the current, accurate to 0.01A, the current can be locked to prevent misoperation;
7. Data group function: You can choose whether to add up the capacity value and running time of the previous stage;
8. Has a powerful serial communication function.

Feature Detail

First, improve the protection mechanism:

1. The power supply end has anti-re protection, re connection does not ;
2. The load end has anti-re protection, the re connection does not ;
3. OVP overvoltage Protection default 25.2V, can modify it yours, after Overvoltage protection, LCD interface fing display OVP;
4. OCP overflow Protection default 4.10A/5.10A, can modify it yours, after overcurrent protection, LCD fing display OCP;
5. OPP power Protection default 25.5w/35.5w, can modify it yours, after power protection, LCD fing display OPP;
6. OTP over-temperature protection after load temperature greaterthan 80℃, over-temperature protection, liquid crystal flicker display OTP;
7. LVP undervoltage Protection default 1.5V, can be set its, after Undervoltage protection LCD fing display LVP, In applications such as battery discharge testing, the setting of suitable LVP can effectively prevent the battery from nsitioning 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: the load current is not zero start statistics, until the next load current is zero, it is believed that the completion of a discharge process, statistical end;
2. Discharge time Statistics: from the current is not zero start statistics, to the next load current is zero, think that the completion of a test 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 fes 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 fes to display "OHP", and when OHP alarm is lifted, the time statistics are automatically emptied;

 

Note: In the absence of the OAP and OHP function, the electronic load will record the discharge capacity and discharge time, turn on the OAH and OHP function, to the set value after the electronic load stopped working; 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 testing.

 

Five, Data group Features:

Divided into "DAT0", "DAT1"

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

DAT1: Fing shows the capacity value and running time of the previous stage, and automatically adds up to the next stage;

 

Interface Operation Instructions:

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" on, and to modify the current of the electronic load in real time by rotating the potentiometer;
2. Short press the en potentiometer key to tole the downlink display content current/power/capacity/time;
3. In any display interface, the rotating en potentiometer will automatically switch to the current display interface;
4. In the current display interface, the press "ON/OFF" on is used to turn the data lofunction on or off, if the data lofunction 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 en potentiometer to prevent misoperation;
5. In the capacity/time interface, the press "on/off" on to empty the corresponding capacity/time data.

 

 

 

Second, the Setup interface operation instructions:

1. In the running interface, the press en potentiometer enters the setup interface;
2. By rotating the potentiometer, adjust the size of the s, increase clockwise, and decrease counterclockwise; switch the s that need to be modified by short pressing the rotary ;
3. In the maximum capacity OAH/Maximum discharge time OHP two interface, short press "ON/OFF" on to select the corresponding function of the turn on or off, if closed, the display "----";
4. In the maximum capacity OAH interface, short press "ON/OFF" on to select the capacity range 9.999Ah/99.99Ah/999.9Ah/9999Ah;
5. settings complete, press potentiometer, exit the Setup interface, set s automatically saved;
