Module Description1.Wide input voltage:9V-120V 2.Minimum voltage difference between input voltage and output voltage is 4V(DC9V-120V for 5V output, DC16V-120V for 12V output). 3. Output voltage 12V/5V selectable (other voltages, please contact us to order) 4. Output current maximum 3A (i.e. constant current value of 3A, when the custom voltage is greater than 12V output current is less than 3A, the power is not recommended more than 30W) 5. Typical operating frequency: 140KHZ 6. High efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency) 7. Light load frequency reduction, improve light load efficiency 8. Small standby current 9. Built-in over-temperature, over-current, output short-circuit protection 10. Built-in soft start 11. Constant voltage and constant current output 12. Operating temperature: industrial grade (-40 ° C to +85 ° C) 13.Module volume:40*30*19mm
How to use?
Connect the connecting wires between the module and the power supply first, and then power up the module. Remember! Remember! (If the input side of the wiring with electricity, it is easy to fire phenomenon, especially when the input power supply voltage is high, and even burn the module's pads.) Select the appropriate power supply power, use a multimeter or voltmeter to measure the output voltage of the module 2, the output voltage is consistent with the voltage of the equipment required to use the electrical equipment or (load) connected to the output side of the module.
