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.
