5A DC-DC LED Schaltregler Charger Power Step Down Module mit USB Port Voltmeter
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 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:
1.Input voltage range:5-36VDC
2.Output voltage range:1.25-32VDC adjustable
3.Output current: 0-5A
4.Output power: 75W
5.High efficiency up to 96%
6.Built in thermal shutdown function
7.Built in current limit function
8.Built in output short protection function
9.Input reverse polarity protection: None (if required, high current diode in series with the input).
10.L x W x H =68.2×38.8×15mm11.Weight: 39g
Application
1.Use as a step-down modules with overcurrent protectionUsage:
(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.
2.Use as a battery chargerUsage:
(1) Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
(3)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 Charging current value.(4)Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)(5)connected to the battery charge.(1,2,3,4 steps as: Output is unloaded, do not connect the battery)
3.Use as a LED constant current driver moduleUsage:
(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.
(1) Output voltage calibration steps
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 voltmeterchange 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current displayvoltage,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.
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 .
