Conversion efficiency: up to 95%
Short Circuit Protection: Yes, constant current value currently set by constant current
Input Reverse Connection Protection: Yes
Output Backflow: No, please add a diode for charging!
Wiring Method: Terminal block or soldering terminal, VIN is input, VOUT is output
Size:100 x 60 x 48mm / 3.94 x 2.36 x 1.89in
Calibration method: This module has a calibration function, so you don't have to worry about the measurement display being inaccurate. Just calibrate once! The module has been calibrated when left factory, if the module displayed inaccurately, you can use the following method to perform a calibration!
Setting instructions:
The "+" button sets the display mode and is divided into three types:
- F-2 mode: alternately display input and output voltages;
Instructions for use: Press the + button to cycle through the three display modes. Press the - button to save and exit. Press the - button alone toswitch the backlight of the LCD screen.
Application range (three applications)
1. Use as a normal step-down module with overcurrent protection
Instructions:
(2) Connect the load, connect the line with a thick point, adjust the "constant current potentiometer " counterclock is to reduce the size, the default factory is 10A, if the actual need is lower than the constant current 10A output, you need to adjust the counter clock The loop current display will change. (The current value displayed by the ammeter is 4A, then the maximum current of the module is limited to 4A, and the red indicator light of the constant current indicator lights when the current reaches 4A)
2. Use as a battery charger
Instructions:
The important thing: Many parents have received the MOS tube when they first started using it. In particular, they are used to recharge the battery and connect the motor to the motor. Remember to add a diode to the output of the module to prevent backflow. Reflow must be burned, diodes are available for sale! Remember, remember! !
(3) The battery is connected to the back end of the anti-backflow diode. The connected line is thick. Adjust the constant current potentiometer . The reverse clock is turned down. The default factory is 10A. If the actual output is lower than the constant current 10A output, It takes a few turns of the reverse clock to adjust the current display to change. (The current value displayed by the ammeter is 4A, then the maximum current of the module is limited to 4A, and the red indicator light of the constant current indicator lights when the current reaches 4A)
3. As a constant current LED driver module
Instructions:
(3) Connect the LED load with a thicker wire, adjust the "constant current potentiometer" reverse clock is to reduce the size, the default factory is 10A, if the actual need is lower than the constant current 10A output, you need to reverse the clock multi-tone A few turns of current display will change. (The current value displayed by the ammeter is 4A, then the maximum current of the module is limited to 4A, and the red indicator light of the constant current indicator lights when the current reaches 4A)
Features:
1Overcurrent protection,more safe and reliable to use. 2Step down voltage adjustable, can be used as battery charger, constant current LED driver module. 3LCD display, dual display of voltage and current. 4With short circuit protection and input reverse polarity protection. 5Wide range of output voltage,large output current and has a maximum conversion efficiency of 95%.
