DC Step Down Converter

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.
•
Specifications:
• Input voltage range: 5-36VDC
• Output voltage range: adjustable 1.25-32VDC
• Output current: 0-5A
• Output power: 75W
• High efficiency up to 96%
• Built in thermal shutdown function
• Built in current limit function
• Built in output short protection function
• Input reverse polarity protection: None (if required, high current diode in series with the input).
• Size: 6.8CM x 3.9CM x 1.5cm.

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.
