USB Load Tester Module Adjustable Constant Current Intelligent Electronic Ageing Discharger Discharge Resistance Load Equipment Module With Cooling FanSpecification:Applicable Voltage Range: DC3.7V-13VCurrent Regulation Range: 0.15A-3.00AContinuous Discharging With 15WFan Working Temperature: 40 ℃Weight:Approx 15gFeature1.The potentiometer of adjusting constant current value which can adjust 0.15A-3A discharge current.Clockwise rotation for increasing, Anticlockwise rotation for decreasing.2. The fan start/stop have Reserved interface. Fan starts or stops depend on the change of temperature. Connecting the middle bonding pad with ON pad, the fan will keep running, connecting the middle bonding pad with OFF pad, the fan will be closed.3.USb Positive and Negative Pole can be extracted separately for wide range of application.4.NTC Thermistor control the fan starts or stops automatically arround 40 ℃.Note:There are two version Electronic Load resistor, only the fan is different, other data are the same.Type A(Cilvil Grade): Oil-bearing FanType B(Industrial Grade): Ball-bearing Fan(Long life ball-bearing fan; High velocity, low noise, powerful; support long time discharging and factory products burn-in test.)We Sell the Type A ONLYPackage Including1 * USB Adjustable Constant Current Module
