Do not exceed maximums

Feature Detail

First, improve the protection mechanism:

  The power supply end has anti-reverse protection, reverse connection does not burn;
  The load end has anti-reverse protection, the reverse connection does not burn;
  OVP overvoltage Protection (default 25.2V, can modify it yourself, after Overvoltage protection, LCD interface flashing display OVP);
  OCP overflow Protection (default 4.10A/5.10A, can modify it yourself, after overcurrent protection, LCD flashing display OCP);
  OPP power Protection (default 25.5w/35.5w, can modify it yourself, after power protection, LCD flashing display OPP);
  OTP over-temperature protection (after load temperature greaterthan 80℃, over-temperature protection, liquid crystal flicker display OTP);
  LVP undervoltage Protection (default 1.5V, 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:

  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;
  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):

  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;
  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: 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 aging testing.

Five, Data group Features:

Divided into “DAT0”, “DAT1”

DAT0: Flashing shows only 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 adds up to the next stage;

Connect your PC via USB port above FZ35. Use serial console with 9600 8 N 1

No alarm status:

Load supply voltage, load current, capacity value, discharge time;

11.90V,0.11A,0.004Ah,00:02 à Load voltage 11.90V, load current 0.11A, capacity 0.004Ah, discharge time 00:02;

Note: If the maximum discharge time is turned on, 00:02 indicates a countdown;

Upload Alarm status code (OVP/OCP/OPP/LVP/OAH/OHP/OTP)

OVP:25.2, OCP:5.10, OPP:35.5, LVP:1.50,OAH:0222,OHP:00:00,

Overvoltage, overcurrent, over power, undervoltage, maximum capacity, maximum discharge time
