            Crystal shell power supply universal power supply

    bandUSBInterface with3Big function, To meet your vast majority of occasions!

Module highlights

1.With crystal shell, safe, practical, convenient, beautiful.

2TheOnboard voltage, current, power meter, you do not have a multimeter can also easily use this module, easier and more intuitive.

3TheOnboardUSBInterface, you can easily charge your digital products.(note:USBThe output voltage is the same as the module output voltage and is not fixed5VOutput toUSBPlease confirm before charging the equipment)

4TheHigh power, high efficiency,5A, Low ripple;

5TheThree functions:

(1) As a general step-down module with overcurrent protection capability;

(2) As a variety of voltage lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery pack) charger used for solar panels, wind turbines and other occasions;

(3) As high powerledConstant current drive module used;

6TheWith constant voltage and constant current two modes, there are indicators that the module is currently in which mode;

7TheWhen used as a lithium battery charger, you can set the float voltage and charge current size, with indicator light

Show whether it is charging or is full;

8TheWith current limiting protection function, even if the output short circuit will not burn the module.

9TheOnboard voltage, ammeter can be self-calibration, there will never be inaccurate!

Application scope

1.As a general step-down module with overcurrent protection capability

Instructions:

(1) Press the right button to adjust the digital meter toDisplay output voltageInterface, adjustment"Constant voltage potentiometer", So that the output voltage to the desired voltage value;

(2) Adjust the digital table toDisplay output currentInterface, direct short-circuit module output (to find a thick wire short-circuit output can be),Adjust at this time"Constant current potentiometer"So that the current value on the digital table reaches the preset overcurrent protection value; (such as the onboard ammeter shows the current value is4A, Then the module maximum current is limited to4A, Current to4AWhen the red indicator light is on)

(3) Connected to the load, work.

2.Used as a battery charger

Non-constant current function of the module can not be used to charge the battery, due to the power consumption of the battery and the charger is a great pressure, resulting in charging current is too large, resulting in battery damage, so the beginning of the battery to use constant Flow charge, when the charge to a certain extent, when the automatic switching back to constant voltage charging.

Instructions:

(1) Determine the battery's float voltage and charge current;(If the lithium battery parameters for3.7V / 2200mAh,Then the float voltage is4.2V, The maximum charge current1C, which is2200mA)

(2) Under no load conditions, adjust the module's digital table toDisplay output voltageInterface, adjustment"Constant voltage potentiometer"So that the output voltage reaches the float voltage;

(3) Adjust the digital table toDisplay output currentInterface, direct short-circuit module output (to find a thick wire short-circuit output can be),Adjust at this time"Constant current potentiometer"So that the current value on the digital table reaches the preset charge current value;
(4) Charging Turn the lamp current factory default0.1Times the charge current;The battery in the process of charging the current is gradually reduced, and gradually from constant current charging to constant voltage charging, if the charge current is set1A, Then when the charge current is less than0.1AOf the time, the blue light off, green light, then the battery charge is completed)
(5) Connected to the battery, charging.

(step1,2,3,4For: input termination power supply, the output does not load the battery)

3.AsledConstant current drive module used
(1) Ok you need to driveledOf the operating current and the maximum operating voltage;

(2) Under no load conditions, adjust the digital table toDisplay output voltageInterface, adjustment"Constant voltage potentiometer"So that the output voltage to achieveledOperating Voltage;
(3) Adjust the digital table toDisplay output currentInterface, direct short-circuit module output (to find a thick wire short-circuit output can be), then adjust"Constant current potentiometer"So that the current value on the digital table to achieve the defaultledWorking current;

(4)led,Test machine.
