  • DC-DC power module.
  • It has an isolation transformer to isolate dangerous voltages and protect personal safety.
  • It also uses photoelectric isolation, the input end and the output end are completely electrically isolated, and the input signal has no effect on the input end.


  •   2.1.Output short-circuit protection:Built-in monitoring chip,output short-circuit protection automatically,after removing the external fault,the monitoring chip will automatically recover after self-test.
  • 2.2.Output overcurrent protection:Built-in current detection chip,automatically protects when the output current exceeds a certain range of rated value.After removing the external fault,the monitoring chip will automatically recover after self-test.
  •   2.3.Output overvoltage protection:dedicated real-time voltage monitoring chip,automatically detects the output voltage for feedback,and automatically protects when the voltage exceeds the rated value.After removing the external fault,the monitoring chip automatically recovers after self-test.
  •   2.4.Input overvoltage protection:When the voltage exceeds the range value,the voltage can be reduced to a relatively fixed voltage value,so as to realize the protection of the subsequent circuit to ensure the safety of the output device.
  •   2.5.Input over-current protection:built-in anti-surge components to ensure the safety of use after the AC-side surge current is input.
  •   2.6.It uses plastic module packaging ,high power density design, dustproof, waterproof and shockproof.
  •   2.7.Its power conversion efficiency is as high as 78%.
  •   2.8.Its input and output are completely isolated,and it is stable and safe to use.
  •   2.9.It has strong anti-interference ability,long service life and high transmission efficiency.
