Product Description
The boost module uses advanced microcontroller and U.S. imports
boost controller, it eliminates the need for a current sense
resistor by utilizing the power mosfet\'s on-resistance, thereby
maximizing efficiency, up to 96.4%. Imported high-power
low-resistance mos transistor, heavy current and high efficiency
schottky, 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
power is 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 you enter 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.
Step 3, 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 of input voltage; press the right button
for more than 2 seconds, release, voltmeter and "IN" LED flashes in
synchronization so that you enter the input 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 on firstly, and then
access the load).
9.input reverse polarity protection: 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.
