Digital Voltmeter Boost DC-DC 100W Power Supply Adjustable 3.5 ~ 35V
I. Introduction : Show some use more advanced microprocessor voltmeter £¬ boost part by the United States imported boost controller £¬ through the use of power MOSFET The on-resistance and eliminates current sense resistor £¬ maximizing efficiency £¬ efficiency up 96.7%. Imports of high-power low resistanceMOSPipe£¬ large package£¬ high current£¬ high efficiency Schottky £¬ extra thickPCBAlignment£¬ high power efficiency and low temperature rise guarantee. Wide voltage operation £¬ when the input and output voltages are in20VOr more can be achieved128WOutput power . Long-life high-frequency switching power supply for high-capacity low resistance(LowESR)Aluminum electrolytic capacitors £¬ so lower output ripple .Module chips are imported£¬ Use of materials £¬ performance and stability ! The module consists of a team of senior engineers studio lasted three months £¬With a voltage meter display£¬ using advanced microprocessor with a voltage meter display£¬ using advanced microprocessorThe development of a moreIntelligent£¬ humane £¬ cost-effectiveModule. Added Benefits Features : 1.OnboardLEDWork lights £¬ work status is more intuitive. 2.A key switch digital tube light off £¬ a key switch input and output voltage measurements. ( Onboard Voltage Indicator "IN" Highlight input voltage "OUT" Highlight the output voltage ) . 3.This product is strong launch £¬Voltmeter self-calibration function ! Never exist voltmeter inaccurate issues! Second£¬ the performance parameters : 1Input voltage :3~35VDirect-current(Note: The input voltage is less than4VOnboard voltmeter failure) 2£¬ Input current :9A(max) 3£¬ Output voltage:3.5~35VDirect-current(This board is a booster plate £¬ the output voltage is> =Input voltage) 4Output current :6A(max) 5Output power:75W£¬ ( When the input and output voltage is greater than20VCan be achieved when128W) 6£¬ Conversion efficiency :96.7%( Highest) 7The output ripple:24mV (TYP) 8Onboard voltage meter range:4 ~ 40VThe error+ -0.1V 9£¬ Short circuit protection: Yes ( limited current14A). Tips : When access to high-power load £¬ due to the impact of current are just machines Assembly limiting self-locking protection £¬ it is recommended to boot£¬ then access to the load. 10£¬ Input reverse polarity protection : None (if necessary£¬ please enter the string into the high current diode ) . 11LongxWidthxHigh= 67 * 43 * 12MM( Excluding copper pillars ) This product is the new double bond portfolio correction voltage function Specific methods are as follows : Output voltage display calibration Step1Adjust the right to make"OUT"Lights £¬ then the voltmeter shows the output voltage ; long press Right2SAfter the above release £¬ voltmeter and"OUT"Synchronous flashing lights £¬ so you enter the output voltage display calibration mode. Step2Short press ( normal speed can be) right once£¬ up the voltage applied voltage value of a unit ; short press the left button down voltage minus the voltage value of a unit ; because the voltage is less than the value of a unit0.1VVoltmeter minimum display to0.1V£¬So you need to continuously press the1-5Times to see changes in the voltmeter0.1VSpecific continuous change according to several key voltmeter0.1V£¬ Depending on the current display voltage£¬ current display higher the voltage £¬ the fewer the number of times pressed . Step3The output voltage adjustment finished £¬ press the button on the right side2SAfter the above release £¬ you can exit the calibration mode£¬ the output voltage display . All parameter settings are saved automatically power down . Input voltage display calibration Step1Adjust the right to make"IN"Lights £¬ then voltmeter displays the input voltage ; long press Right2SAfter the above release £¬ voltmeter and"IN"Synchronous flashing lights £¬ so you enter the input voltage display calibration mode. Step2£¬3Consistent with the output voltage display calibration methods. Note : Before shipping the product have been tested more than three times the voltage display accuracy guarantee0.1VInside £¬ the calibration function is to meet your higher accuracy requirements and design £¬ ease of use . Third£¬ the application range: 1£¬DIYA power supply£¬ input5VCan £¬ output can be5-35VAdjustable. 2For your electronic device powered£¬ according to your system can set the output voltage value . Such as3.7VL lithium5VDo mobile power£¬7.4V Or 12V Liter 19 To the laptop power supply. 3£¬ As the car power supply for your laptop £¬PDA Or a variety of digital products supply.
