DC DC-DC 3~35V to 3.5~35V Booster step up Step-up module Converter Regulated Power Supply VoltMeter
 
 
 
 
 
Product Description
 
The boost module uses advanced microcontroller and U.S. imports boost controller,it eliminatestheneed for a current sense resistorby utilizing the powermosfet\\\'s on-resistance,thereby maximizing efficiency,up to 96.4% .Importedhigh-power low-resistancemostransistor, heavy current and high efficiencyschottky,wider and thicker PCB traces,is a guarantee of high-power and low temperature rise. When the input and output voltage is greater than 20V,the module up to 128W output power.
 
Features:
1.LED power indicator.
2. Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the poweris disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value).
3.Special launch, the voltmeter calibration function,will never exist voltmeter inaccurate!
Voltmeter calibration method:
(1)Output voltage calibration steps
Step 1,adjust the right button so that "OUT" LED lighted, the voltmeter shows the value of output voltage;Press the right button for more than 2 seconds, release, voltmeter and "OUT" LED flashes in synchronization so that youenter the output voltage calibration mode.
Step 2,press the right button (normal speed), the voltage value is adding up a unit;Press the left button, minus a unit;Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V,how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.
Step3,press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.
(2)Input voltage calibration steps
Step 1,adjust the right button so that "IN" LED lighted, the voltmeter shows the value ofinput voltage; press the right button for more than 2 seconds, release, voltmeter and "IN" LED flashes in synchronization so that you enter theinput voltage calibration mode.
Steps 2 and 3, consistent with the output voltage calibration method.
 
Performance parameters
1.input voltage range:3~35VDC(Note: the input voltage is less than 4V, voltmeter failure)
2.input current:9A (max)
3.output voltage range:3.5~35VDC(please to ensure that output voltage above on input voltage)
4.output current: 6A (max)
5.output power: 75W (when the input and output voltages greater than 20V up to 128W)
6.conversion efficiency: 96.4% (max)
7.voltmeter range: 4 to 40V, error±0.1V
8.short circuit protection: yes(limit current 14A).(Note: connected to high-power load, just switched on the impact of current very general meeting current limiting self-locking protection, it is recommended to be switched onfirstly, and then access the load).
9.input reversepolarityprotection: None (if required, high current diode in series with the input).
10.L x W x H = 67 * 43 * 12mm
Application:
1.DIY a regulated power supply, 5V input can be output 5-35V adjustable.
2.The power supply for your electronic equipment.For example,3.7V lithium boost to 5V for mobile power;7.4V or 12V boost to the laptop power supply to 19V.
3.As the vehicle power supply for your laptop, PDA or a variety of digital products supply.
