Type:Logic ICs
Condition:New
LCD screen with voltage, current double display, no multimeter, but also easy to use, powerful! Crystal shell finished power universal power supply, suitable for high power LED constant current drive, rechargeable lithium batteries (including 4V, 6V, ferroelectric), 12V, 14V, 24V, nickel cadmium battery charging NiMH battery (batteries) charging, solar panels, wind power generator step-down regulator. The price is the shell price! Upgrade the new version, new input, anti - connect, anti - function!
ExplainAfter receiving the baby, please look at the wiring method, and then power test, and then solder, because of their own wrong line, misoperation or DIY changes are not warranty Oh!
Calibration method:The module has a calibration function, so you don't have to worry about measuring inaccuracy. If you find that the display is not correct, you can calibrate it by the following methods. Just use it for the first time! Received baby suggested the following method for a calibration!
Voltage calibration:Power is turned off, press the "Settings" button, enter the power, voltage calibration mode, the LCD screen began flashing, release the keys, click "Settings" button to add, "OK" to reduce the input voltage, the calibration is correct, such as: the input voltage is 1Two65V, voltage adjustment will be at that time 12.65V, automatically save 2 seconds after the power out is complete calibration!
Special explanation:Customers have just received the baby, reflecting the output voltage can not be adjusted, because the module factory, the default output voltage of about 20V. When you encounter this problem, please turn the ADJ-V potentiometer counterclockwise for more than 10 laps until the voltage changes, and then you can adjust the voltage with the module.
Upgrade new version, increase input, anti connect, reverse function LCD screen with voltage, current double display, powerful!
The use of four layers of design, workmanship, practical material, on the more stable, more reliable Crystal shell, power supply, power supply
Module parameter Input voltage: 7V-36V Output voltage: 2V-32V, adjustable continuously
(used only for step-down modules. Input must be greater than output 1V or more) Output current: adjustable, maximum 10ARecommended for use in 8A, 5A or 70W below the room temperature can be natural heat dissipation, more than please strengthen the heat Oh!Suggest a small fan!Fans are sold here!
Constant current requires more than 2V output voltage to adjust, Current regulation only works in a constant current state.) Output power: maximum 150W (recommended for use in 100W, high pressure differential, please reduce power) Operating temperature: -20~+75 degrees (pay attention to the power tube temperature, more than please strengthen the heat dissipation) Operating frequency: 300KHz Conversion efficiency: maximum 95% Short circuit protection: Yes, constant current is set at constant current value Input reverse connection protection: Yes
New features added to the upgrade!) Output counter reflux: No, for charging, please add a diode! This shop is on sale! Installation: two acrylic board, on 8 Pillars, 8 3mm screws,
Installation is easier when you install the button! Connection mode: connection terminal or welding terminal, IN is input, and OUT is output Module size: long 80mm, width 53mm, high 35mm Weight: 132g

The outer shell of the module shell is provided with an opening of the fan, and can be used for increasing the cooling of the fan, and the fan is sold in the shop! The fan needs another shot! 
Setting instructions:
Set the key to set the display mode, divided into three kinds:
1, F-0 mode: display output voltage;
2, F-1 mode: display input voltage;
3, F-2 mode: alternate display input and output voltage;
Directions: press the settings button, the cycle shows three display modes, and the corresponding indicator light is on or off,Press OK to save and exit,Press the OK button individually to switch the LCD screen back light.
Application range
Note that the constant current adjustable current, must be the actual output load current is greater than the set current will be a constant current mode, or a constant pressure of work, not to the current 2A, is connected to any device 2A, also hope to know. The output voltage is above 2V, constant current will take effect!
1.Used as an ordinary buck module with overcurrent protection capability
Usage method
(1)No load condition,adjustConstant voltage potentiometer ADJ-V"Make the output voltage up to the voltage you want;
(2)The output of the direct shorting module (looking for a thick wire or tweezers shorted to the output terminal),Note: do not adjust the voltage when shorting),Adjust nowConstant current potentiometerADJ-I"The display current value reaches the preset over-current protection value; orYou can adjust the current with the load.For example, the current value displayed by the onboard ammeter is...4AThen the maximum current of the module is limited to4ACurrent to4AConstant current indicator red indicator light on
(3Connect the load to work.
2.Used as a battery charger
Usage method
(1) determine the float voltage of the battery and charging current;(if the lithium battery parameter is3.7V/2200mAh,As for the floating voltage4.2VMaximum charge current1CThat is,2200mA)
