1. Product Features

• With a separate power supply design, the measurement circuit and display circuit of the product its do not consume the energy of the power supply under test, and the measurement is more accurate and reliable.

• LCD display, which can display load input voltage, input current, input power, discharge time, discharge maH, product temperature and other information.

• Complete protection mechanism with undervoltage protection, overvoltage protection, overcurrent protection, overpower protection and overtemperature protection.

• The current adjustment uses a long-handle potentiometer, which can be rotated by hand without the need for additional tools such as a screwdriver.

• With voltage and current correction function to meet the high precision requirements of customers.

• s can be stored off power.

•Apply to various power sources product power, charger, charging treasure, etc. or functional test, test various battery capacity discharge characteristics, desktop small load.

3. Product details

3.1 Detailed functions

    1, LCD display

       In normal mode, the LCD displays the load input voltage and load temperature up; the downstream shows the load current, power, capacity, and discharge time.

       In protected mode, the LCD displays the protection code.

       In the setting mode, the LCD displays various setting codes and thresholds.

    2, load current regulation

       The magnitude of the discharge current can be adjusted by a potentiometer.

    3, sound and light alarm

       When the load is turned on, the RUN indicator is always on and the is not ringing. When the load is off, the RUN indicator is off and the is not ringing. After entering the protection mode, the will drop the alarm and the RUN indicator will f.

    4, ligent fan cooling

       The fan automatically starts when the load discharge power is greater than 10W or the load temperature is greater than 40°C.

    5, discharge capacity and discharge time automatic statistics, as as the load is turned on RUN indicator is always on to start statistics, turn off the load RUN indicator is not lit, stop statistics, statistics support power-down storage, clear statistics only one The method is to press the '-''' on when the LCD displays the discharge capacity or discharge time. Please clear the statistics before starting the statistics. The maximum discharge capacity OAH and maximum discharge time OHP can be set to on or off in the setup mode, and the threshold size can be set. When the threshold is exceeded, the load is automatically turned off, enabling unattended discharge experiments.

    6. Perfect and hardware protection mechanism, and the protection threshold can be adjusted. After protection, the output is turned off.

     Hardware protection:

       Both the module power port and the load input port have anti-re protection.

      protection:

     OVP - Overvoltage protection default 25.5V, can be set by yours, after overvoltage protection, RUN indicator fes, LCD interface displays OVP;

     OCP-overcurrent protection default 4.10A/5.10A, can be set by yours, after overcurrent protection, RUN indicator fes, LCD displays OCP;

     OPP- over power protection default 25.5W/35.5W, can be set by its, after over power protection, RUN indicator fes, LCD fes OPP;

    OTP - Over temperature protection over temperature protection after load temperature is greater than 80 °C, RUN indicator fes, LCD displays OTP;

     LVP - undervoltage protection default 1.5V, can be set by yours, after undervoltage protection, RUN indicator fes, liquid crystal display LVP, in battery discharge test and other applications, set the appropriate LVP, can effectively prevent battery over discharge, so as not to damage battery

    7. The load is turned off by default. After power-on, press the ON/SET on to start or shut down.

    8, all settable s can be stored off power.

3.2 Detailed operation

   1, the operation of the potentiometer

    The potentiometer is used to adjust the load discharge current, clockwise rotation, the current value increases, and the counterclockwise rotation current value decreases.

  2, on operation detailed

4. Note

4.1 Please read the manual carefully before using this product! If the module is damaged due to incorrect use, or if the device is removed without authorization, it will not be returned.

4.2 The power supply voltage should be DC5V, DC power supply, do not use AC power! If the voltage is over voltage, the module may be ed after power-on;

4.3 The voltage at the load input should be between DC 1.5V and 25V. The current should be below 4A ZK-FX25 or 5A ZK-FX35.

4.4 The load input port should not be short-circuited, otherwise the product will be t.

4.5 Be careful not to get wet of the module. Do not short-circuit the components on the board. Do not touch the pins and pads of the components on the board.
