[2 Pack] Dc-Dc 5A Buck Converter 4-38V To 1.25-36V Step-Down Voltage Regulator High Power Module With Led Display

Features:- High Power Dc-Dc Step-Down Module- Thickened Circuit Boards- Advanced Solid-State Capacitor- Short Circuit And Over-Temperature Protection- 100% Tested, Sealed In Anti-Static Packagingkindly Note:1. Input Voltage Must Be 1.5 V Higher Than The Output Voltage, No Boost2. Do Not Reverse The Input And Output Interface3. Keep Output Under 5A (Or 75W), And Use A Heat Sink When For A Long Time Workinghow To Calibrate The Digital Tube Voltmeter(Optional Steps For The Person Who Need A Highly Accurate Voltage Value)1. Short Press The Left On/Off Button To Start Up The Digital Tube Voltmeter. Long Press(>1S, 4 Seconds) The Left Button To Enter Self-Calibration Of Voltage Measurement(Calibration Range: -0.5-0.5V, Factory Setting Is 0.0).In Indicator Lights = Input Voltage Measurement Calibration Starts. Then, Long Press(>2 Seconds) The Right Mode Button, Out Indicator Lights = Output Voltage Measurement Calibration Starts. Tap The Left / Right Button To Reduce / Rise By One Unit (Since The Voltage Value Of One Unit Is Less Than 0.1V, You Need To 1-5 Times Tap The Button Continuously, So That The Voltmeter Can Change By 0.1V)3. After Calibration, Long Press(>2 Seconds) The Right Mode Button To Preserve The Adjusted Value(No Loss With Outage) And Back To Normal Voltage Display.Specifications:- Model: Xl4015E / Digital Tube Voltmeter - Input Voltage: Dc 4V - 38V- Output Voltage: Dc 1.25V - 36V (Adjustable)- Output Current: 0-5A ( Recommended Working Current < 4.5A)- Conversion Efficiency: 96% (Max.)- Switching Frequency : 180Khz- Operating Temperature: -45?
