DROK USB Load Tester, Electronic Load Test Resistor Module 25W LD25 USB and Type C Interface Discharge Adjustable Constant Current 0.25A-4A Intelligent Temperature Control with Cooling Fan

What is it: it is a USB intelligent temperature control electronic load; with high power, high current, high voltage and intelligent control features.
Easy Opeartion: set the load to resume normal operation manually or automatically after releasing the protection condition; can freely set the boot state to be on or off by default; 4-bit led digital display; check the load voltage value / current value / power value; intelligent temperature control cooling fan; Precision adjustable potentiometer; Over-voltage protection / overpower protection / over temperature protection.
Protection Function: OVP overvoltage protection (25V-30V overvoltage protection, digital display OVP, permanent damage after more than 30V); OPP over-power protection (load temperature is greater than 80 °C, the device stops working, digital display OTP); OTP over-temperature protection (power greater than 25W, equipment stops working, digital display OPP).
Application: can provide 4A, 25V, 25W (3 values can not used over range) constant current test discharge task. The friendly human-computer interface and excellent performance indicators can meet the diverse testing needs. It is suitable for measuring the output current capability of the charger, using the bulk aging test of the charger factory, and measuring the quality of the Micro USB charging cable and the Type-C charging cable.
Note: the usb tester module has no reverse connection protection, the input polarity cannot be reversed, otherwise the product is permanently damaged and cannot be repaired.
