Module parameters
Input voltage: 7V-40V  
Output voltage: 1.5-35V adjustable (can only be done step-down module, the input must be greater than the output of 1.5V or more)
Output current: adjustable, 10A ( recommended in 8A, 5A 70W or less at room temperature can be natural cooling, please enhance heat dissipation exceeds oh proposes to add a small fan!! Constant need to adjust the output voltage of 2V than before ,  current regulation only in the constant state will play a role. )
Output Power: Max 150W (recommended in 100W, large pressure, please reduce power use)
Working temperature: -20 ~ + 75 degrees (note the use of the power transistor temperature exceeds please enhance heat dissipation)
Operating frequency: 300KHz
Conversion efficiency: up to 95%
Short circuit protection: Yes, constant current value currently set
Input Reverse Polarity Protection: None
Installation: up and down both sides of the acrylic sheet, eight pillars, eight 3mm screws, in turn, easier to install when you install the key Oh!
Connection: terminals or solder terminals, VIN is the input, VOUT output
Module dimensions: length 80mm width 53mm height 35mm
Weight: 132g

Applications
1. Use as an ordinary step-down modules with overcurrent protection capabilities
Instructions:
( 1 ) under no-load conditions, adjust the "constant-V potentiometer the ADJ" , so that the output voltage reaches the value you want;
( 2 ) outputs directly shorting module (coarse find articles or forceps wire shorted to the output terminal, NOTE: Do not short-circuited when the tune voltage ) , this time adjusting "constant potentiometer the ADJ-the I " make display the current value reaches the preset value of the overcurrent protection; (such as on-board ammeter shows the current value of 4A , then the module maximum current is limited to 4A , the current to 4A constant current LED red light)
( 3 ) connected to the load and work.

2. Use as a battery charger
 Instructions:
( 1 ) determines that the battery float voltage and charging current ; (lithium parameters if 3.7V / 2200mAh, then float voltage of 4.2V , the maximum charging current . 1C , namely 2200mA )
( 2 ) under no-load conditions, adjust the "constant voltage potentiometer the ADJ-V " so that the output voltage reaches the float voltage ;
( 3 ) outputs directly shorting module ( find bars thicker wire or forceps can be connected to the output short, NOTE: Do not short-circuited when the tune voltage ) , this time adjusting "constant potentiometer the ADJ-the I " make displays the current value of the charging current reaches a preset value ;
( 4 ) Charge turn lamp current factory default is  0.1 times the charging current ; ( Battery during charging current is gradually reduced, gradually converted to constant voltage charging by the constant current charging, if the charging current is set . 1A , then when the charging current is less than 0.1A when charging indicator light off yellow, full blue indicator lights up and the battery is fully charged ), charging is complete, disconnect the battery terminals, then disconnect input off to prevent battery reflux damage the module!
( 5 ) connected to the battery charge.

3. as a constant current LED driver module
( 1 ) determine that you need to drive LED operating current and the maximum operating voltage;
( 2 ) under no-load conditions, adjust the "constant voltage potentiometer the ADJ-V " so that the output voltage reaches the LED operating voltage ;
( 3 ) outputs directly shorting module ( find bars thicker wire or forceps can be connected to the output short, NOTE: Do not short-circuited when the tune voltage ), then adjust the "constant potentiometer the ADJ-the I " make the current value reaches the preset display LED operating current ;
( 4 ) connected to the LED , the test machine.

Note that the adjustable constant current, the output current must be greater than the actual load time will set the current constant current mode, constant voltage mode of operation or is not transferred to current 2A, is connected to any device becomes 2A, and also hope known.

Voltage Calibration:
loss of power, hold down the "set" key, the power to enter the voltage calibration mode, the LCD screen starts flashing, release the setting key, press the "Settings" button to add, "OK" for the reduction, alignment to the correct input voltage, such as: the input voltage is 12.65V, then the voltage was adjusted to 12.65V, are automatically saved after 2 seconds, power is withdrawn calibration is complete!

Setting Description:
Setting key to set the display mode is divided into three types:
1, F-0 mode: Display output voltage;
2, F-1 mode: Display input voltage;
3, F-2 mode: alternating input and output voltage;

Instructions:
Press the "Settings" button to cycle through the three display modes, the corresponding indicator will be on or off, press the "OK" button to save and exit, a separate press "OK" button to switch backlit LCD screen.
