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 LVP 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 the load input voltage and load temperature upstream; the downstream displays the load current, power, capacity and discharge time. protection mode, the LCD displays the protection code. setting mode, the LCD screen displays each setting parameter code and parameter threshold. Load current adjustment:the size of the discharge current can be adjusted by potentiometer sound and light alarm:when the load is turned on, the RUN indicator light is always on and the buzzer does not sound; when the load is turned off, the RUN indicator light is not on and the buzzer does not sound. After entering the protection mode, the buzzer will sound and the RUN indicator will flash. Intelligent fan cooling:automatic start when the load discharge power is greater than 10W or the load temperature is greater than 40℃. Discharge capacity and discharge time are automatically counted: statistics are started as long as the load is turned on (RUN indicator is always on), the load is turned off (RUN indicator is not on), and statistics are stopped.
