DC Step Down Converter Step down Adjustable Power Module Charge
DC Step Down Converter
Rp 125.000
Specification:
Highlights:
·
Contains
the voltmeter, ammeter, power meter, USB interface for charging the digital
products.
Note:
1. When you use the product, the module
inputs and outputs to be isolated from ground.
2. USB output voltage is
consistent with the module, not a fixed 5V output. When charging for digital
equipment, make sure the USB output voltage is 5V.
3. Some customers report:
"The module can not adjust the output voltage is always equal to the input
voltage." When you encounter this problem, please counterclockwise
rotation of the "voltage potentiometer" 10 laps or more, then use the
module you can adjust the output voltage. Because the factory default output
voltage of about 20V.

Application:
1.Use
as a step-down modules with overcurrent protection:
·
(1) Adjust the right
button so that “OUT” LED lighted, Digital meter shows the value of output
voltage ,adjust the “voltage potentiometer” so that the output voltage reaches
the value you want.
·
(2) Adjust the right
button so that Digital meter shows the value of output current;Wire shorted
output terminal, then adjust the “current potentiometer” so that the output
current reaches a predetermined overcurrent protection value. (For example, the
Digital meter displays the current value of 4A, then you can use the module to
a maximum current of 4A).
·
(3) Connected to the
load.
3.Use
as a LED constant current driver module:
·
(1)Adjust the “voltage
potentiometer” so that the output voltage reaches the value you want.
·
(2)Adjust the right
button so that Digital meter shows the value of output current;Wire shorted
output terminal, then adjust the “current potentiometer” so that the output
current reaches a predetermined LED operating current.
·
(3)Connect LED, work.
·
(1,2 steps as: Output
is unloaded, do not connect LED).
Voltmeter
and ammeter calibration method:
(1)
Output voltage calibration steps:
·
Step 1, adjust the
right button so that “OUT” LED lighted, Digital meter shows the value of output
voltage; Press the right button for more than 2 seconds, release, Digital meter
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, Digital meter shows the value of input
voltage; press the right button for more than 2 seconds, release, Digital meter
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.
(3)Output
current calibration steps:
·
Step 1, adjust the
right button so that Digital meter shows the value of output Current. Press the
right button for more than 2 seconds, release, Digital meter flashes in synchronization
so that you enter the output current calibration mode.
·
Step 2,Connected to
the load, ammeter in series, adjust the right and left button to change the
display of digital meter, so that is consistent with the ammeter display.
