Feature description

Load Features:

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);(To achieve unattended power aging testing)

5. Intelligent temperature-controlled fan, when the power is greater than 10W or the temperature is greater than 40 ℃ fan starts automatically；

6. With a rotary coded potentiometer, the current can be precisely adjusted to an accurate 0.01A, The current can be locked to prevent misoperation;

7. You can set the load to manually or automatically return to normal work after the release of the protection mechanism (REC)

8. Data group function: You can choose whether to add up the capacity value and running time of the previous stage;

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.
