DC DC Converter Adjustable Power Supply DC-DC Step Down 3A LM2596HVS LM2596HV DC Step Down Buck Converter Power Input 4.5V-60V
Input voltage : DC 4.5 - 60V
Output Voltage : DC 3- 40V
Output Current : 3A(MAX)
Conversion efficiency : 92% (MAX)
Switching frequency : 150KHZ
Output ripple : 30mV (MAX)
Working Temperature : industrial (- 40 ° c to +85 °c)
Size : 43*21*14 mm
The input volts should less than 55v
When adjust the blue potentiometer ,please use a multimeter to monitor the voltage
Rotating Clockwise can rise the voltage while rotating counterclockwise could lower the voltage
When the module output voltage can not be adjusted ( the output voltage is always equal to the input voltage ) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.
