Features-With a separate power supply design, the measuring circuit and display circuit of the product itself do not consume the power of the power supply under test, and the measurement is more accurate and reliable.-LCD display, which can display the load input voltage, input current, input power, discharge time, maH discharge, product temperature and other information.-Complete protection mechanism with undervoltage protection, overvoltage protection, over-current protection, over-voltage protection, overvoltage and overheat protection.-The current regulation 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 requirements of customers.-Parameters can be kept off power.-Apply to different power sources (product power, charger, charging device, etc.) aging or functional test, test different characteristics of capacity discharge battery, low load on the desktop. Package Included:1*Battery Load Capacity Tester-Product Details Detailed Functions LCD Display:In normal mode, the LCD displays the load input voltage and load temperature; Downstream shows load current, power, capacity, and discharge time. In protected mode, the LCD displays a security code. In setting mode, the LCD displays various setting parameter codes and parameter thresholds. Regulation load current: The magnitude of the discharge current can be adjusted by potentiometer. Sound and Light Alarm: When the load is on, the gear indicator is always on, and the buzzer does not ring. When the load is off, the gear indicator is off and the buzzer does not ring. When you enter the protection mode, the buzzer will drop an alarm and the startup indicator will flash. Intelligent cooling fan: The fan starts automatically when the load discharge power is greater than 10W or the load temperature is greater than 40°c. Discharge capacity and discharge time automatic statistics as long as the load is on (the start indicator is always on) to start statistics, turn off the load (the start indicator is not on), stop statistics, statistics support power storage, Clear statistics only one 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 turn on or off in configuration mode, and the threshold size can be set. When the threshold is exceeded, the load is automatically shut down, allowing unattended discharge experiments. The perfect software and hardware protection mechanism and software protection threshold can be adjusted. After the software is protected, the output is disabled. Hardware Protection: Both the module's power socket and loThe ad input port has reverse protection. Software protection:Ovp-surge protector (default 25.5V, can be set by yourself, after surge protection, the start indicator flashes, LCD interface displays OVP); OCP-overcurrent protection (default 4.10A/5.10A, can be set by yourself, after overcurrent protection, the start indicator flashes, OCP LCD displays); Surge protection (default 25.5W/35.5W, can be set by yourself, when power protection is exceeded, the start indicator flashes, LCD flashes OPP); OTP-over-temperature protection (over-temperature protection after load temperature is greater than 80°c, working indicator flashes, OTP LCD display); LVP-undervoltage protection (default 1.5V, can be set by yourself, after undervoltage protection, working indicator flashes, LVP liquid crystal display, in the battery discharge test and other applications, set the corresponding LVP, can effectively prevent the battery from over-discharging, so as not to damage the battery)The load is disabled by default. Once powered on, press the on/SET button to start or turn off. All set parameters can be stored outside of the power supply. Working Detail:Potentiometer Operation:The potentiometer is used to adjust the load discharge current, clockwise rotation, the value of the current increases, and the value of the counterclockwise rotation current decreases.
