DC 3.7-20V 3A 25W Load Tester Electronic Test Resistor Module USB&Type C Interface Adjustable Constant Current

DC 3.7-20V 3A 25W Load Tester Electronic Test Resistor Module USB&Type C Interface Adjustable Constant Current 1. Intelligent start and stop fan, optimized fan drive circuit, more stable wind power and wider working voltage.2. High-current USB, dual interfaces are more widely applicable, and can be used in parallel if the power is not enough.3. Upgrade the high-power tube with higher fan speed and better heat dissipation, resulting in higher load power.4. Intelligent over-temperature adjustment to avoid excessive temperature damage to the module or other safety issues when overloaded.5. Wide range of applications: The main purpose is power aging, battery discharge, factory testing, etc. It is suitable for various production aging uses.Voltage: DC 3.7-20VWorking current: less than equal 3AMaximum power: 25WInterface: USB/Type-CHeat dissipation method: all-aluminum fan heat fin + intelligent temperature-controlled fanModule interface:USB/Type-C: Input 3.7-20V power supply, and the two interfaces are parallel inputs.ON FAN short circuit: Force the fan to rotate.OFF FAN short circuit: forced to stop the fan rotation.Blue potentiometer: clockwise increases current, counterclockwise decreases currentTips: The product may be updated constantly, The Actual Product May Have Slight Differences Or Color Differences the color and appearance may be changed, please don't mind.
