Voltage input 4.5-30V / Output 1.25-26V (requires input voltage is greater than the output voltage)
IN + input positive / IN-input negative
Positive output OUT + / OUT-output negative
Note that input and output can not be reversed. Reverse may burn module
Input: DC 4.5V to 30V (input voltage must be higher than the output voltage can boost 1.5v above.)
Output: DC 1.25V to 26V
Dimensions: L * W * H (4.3cm * 3.0cm * 1.2cm) size is not as small as possible, considering the heat, more conducive to heat a large area points!
5A diode SS34 optional components.
Clockwise onboard potentiometer, the output voltage increases. Counterclockwise to adjust the potentiometer, the output voltage decreases.
Sided wiring, large copper bottom to ensure excellent heat dissipation more! Long-term work can be rated in 2A. Expanded to maximum output power 20W, more convenient plus radiator, power output greater!
Note: long working hours is recommended for use in less than 2A of current , while adding a heat sink (10W output above ) ;
As the buck module , in order to ensure stable output , keep a minimum 1.5V differential .
The voltage regulator
Access to power, adjust the blue potentiometer knob ( clockwise general boost, buck counter-clockwise ) and use a multimeter to monitor the output voltage reaches the needed voltage.
1. welding, soldering directly to the power line at the input ( output ) port ;
2. solder pins, the pins can be inserted through a lead or plug in the hole using the board ; may also be soldered directly to the PCB after adding pins .
2 to the power electronic devices. When the device requires 4.5-30V power supply, with this module you can easily put the voltage to the desired voltage and solve problems.
3 Operating voltage test system, you can use this module to do the project when debugging a variety of voltage test system operating voltage range, very easy and convenient.
1, vehicle power supply , simply enter the module powered cigarette holder termination point on the car , you can adjust the potentiometer , the output voltage can be adjusted between the 1.25-26V , for your phone , MP3, MP4, PSP charging and many other devices powered, very simple and convenient .
