Use high-quality materials with guaranteed quality. Small size and exquisite appearance. Stable and performance Easy to use. Wide range of applications. load power supply voltage: DC5.0V (with anti-reverse connection). load power supply current: less than equal 200mA. load input voltage: DC1.5V-25V (with anti-reverse connection). load input current: 0.00A-5.00A voltage accuracy: (1 word). current accuracy can be calibrated: (1 word). heat dissipation method can be calibrated: intelligent temperature control fan all aluminum. fan speed: heat sink: 8000rpm. working environment temperature:-15-50 . undervoltage protection threshold: default 1.5V (adjustable between 1.5V-24.5V). overvoltage protection OVP threshold: default 25.0V (adjustable between 1.5V-25.0V) LCD screen display: In normal mode, the LCD screen displays load input voltage and load temperature upstream; the downstream displays load current, power, capacity and discharge time. protection mode, the LCD displays protection code. setting mode, the LCD screen displays each setting parameter code and parameter threshold. Load current adjustment:the size of discharge current can be adjusted by potentiometer sound and light alarm:when load is turned on, the RUN indicator light is always on and buzzer does not sound; when load is turned off, the RUN indicator light is not on and buzzer does not sound. After entering protection mode, the buzzer sound and RUN indicator flash. Intelligent fan cooling:automatic start when load discharge power is 10W or load temperature is 40. Discharge capacity and discharge time are automatically counted: statistics are started as long as load is turned on (RUN indicator is always on), the load is turned off (RUN indicator is not on), and statistics are stopped. Statistics support power-down storage. There is only one way to clear statistics, which is to the key-when LCD screen displays discharge capacity or discharge time-. Before starting statistics, please clear statistical data first. The maximum discharge capacity () and maximum discharge time (OHP) can be set to be turned on or off in setting mode. When threshold is turned on, the threshold can be set. Hardware protection: module power supply port and load input port have anti-reverse connection protection. software protection: OVP overvoltage protection (default 25.5V, can be set by itself, after overvoltage protection, RUN indicator flashes, LCD interface displays OVP) ; OCP overcurrent protection (default 4.10A/5.10A, can be set by itself, after overcurrent protection, RUN indicator flashes, LCD OCP) ; OPP over-power protection (default 25.5W/35.5W, can be set by itself, after over-power protection, the RUN indicator flashes and liquid crystal flashes to display OPP) ; undervoltage protection (default 1.5V, can be set by oneself, after undervoltage protection, RUN indicator flashes, liquid crystal display , in battery discharge test and other applications, set appropriate , it can effectively prevent battery from being over-discharged to avoid damage to battery) the load is turned off by default. the ON/SET key to start or close after power-on. All settable parameters can be stored in power-off Color: Blue Material: PCB Package Contents: 1 * Battery Capacity Tester Only above package content, other products are not included. Note: Light reflection and different displays may cause color of item in picture a little different from real thing. The measurement allowed error is +/- 1-3cm.
