1. Product Features• With a separate

power supply design, the measurement circuit and display circuit of the product

itself 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.• Parameters can be

stored off power.•Apply to various

power sources (product power, charger, charging treasure, etc.) aging or

functional test, test various battery capacity discharge characteristics,

desktop small load.2. Product illustration

3. Product details3.1 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 parameter codes and

parameter 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 buzzer is not

ringing. When the load is off, the RUN indicator is off and the buzzer is not

ringing. After entering the protection mode, the buzzer will drop the alarm and

the RUN indicator will flash.    4,

intelligent 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 long 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 '-''' button 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 software and hardware protection mechanism, and the software protection

threshold can be adjusted. After software protection, the output is turned off.     Hardware

protection:       Both

the module power port and the load input port have anti-reverse protection.     Software

protection:     OVP

- Overvoltage protection (default 25.5V, can be set by yourself, after

overvoltage protection, RUN indicator flashes, LCD interface displays OVP);     OCP-overcurrent

protection (default 4.10A/5.10A, can be set by yourself, after overcurrent

protection, RUN indicator flashes, LCD displays OCP);     OPP-

over power protection (default 25.5W/35.5W, can be set by itself, after over

power protection, RUN indicator flashes, LCD flashes OPP);    OTP

- Over temperature protection (over temperature protection after load

temperature is greater than 80 °C, RUN indicator flashes, LCD displays OTP);     LVP

- undervoltage protection (default 1.5V, can be set by yourself, after

undervoltage protection, RUN indicator flashes, 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 button to

start or shut down.    8,

all settable parameters 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, button

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 burned 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 burnt.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.4.6
