LM2596 DC-DC adjustable voltage reduction module/ 4.5-30V input/ 1.25-26V output (BEA2)

Input the ultra wide voltage 1.25-4.5-30V, output adjustable voltagr 1.25-26V (input voltage should be higher than the output voltage)
IN+: input positive IN-: input negative
OUT+: output positive OUT-: output negative
Attention: cannot reverse input and output, will lead to circuit burnt out.
Input: DC 4.5V to 30V (input voltage should be 1.5 V higher or above than the output voltage. Cannot step up voltage)
Output: DC 1.25V to 26V
Features:
Size: length * width * height: 4.3 cm * 3.0 cm * 1.2 cm. The size is not the smaller the better, bigger size is better for heat dissipation!!!
Diode SS34 uses 5A element, not as small as sesame, you will know if you have used one.
Clockwisely adjust the potentiometer on the board to increase output voltage, counterclockwise to decrease.
Double-sided wiring, large area copper clad at the bottom guarantees better heat dissipation! Can work for a long time in rated 2A, maximum output power expands to 20W, making it more convenient to add external radiator!
Note: for long time working, suggest current within 2A, use cooling fin at the same time (more than 10W output);
Because it is a voltage reduction module, in order to guarantee the stability of the output, please maintain minimum 1.5V voltage difference.
Voltage regulation
power up, adjust the blue potentiometer knob (generally, clockwise step-up, counterclockwise step-down), meanwhile, use multimeter to monitor the output voltage until it reaches needed voltage.
Wiring
1. welding, directly weld the power line to the input (output) port;
2. pin welding, use wire to lead out and insert pin or use a breadboard; or add pin and then weld it on PCB directly.
Application example
1. vehicle-mounted voltage-stabilized power source, contact the input port of this module to the car's power supply, adjust the potentiometer, output voltage 1.25-26V, can supply power for your mobile phone, MP3, MP4, PSP charging etc., very convenient.
2. supply power for electronic equipment, when a device needs 4.5-30V power supply and there is no corresponding voltage power at hand, with this module, voltage can be adjusted to the voltage required, problem solved.
3. system operating voltage test, when doing a project, you can easily use this module to test various working voltage range.
