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 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 Usage: (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 charger Usage: (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) (2)Under no-load conditions, adjust the ��Voltage potentiometer�� so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V) (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 module
