1. Switch: Power electronic component is working at swich status not linear status
2. High frequency: Power electronic component is working at high frequency status not the low frequency closed to power frequency
3. DC: The output voltage of power supply is DC not AC
Working characteristic:
1. Small size, light weight
2. Small power waste
3. High efficiency: Power transistor is working at switch status, so the power waste is small, conversion efficiency is high, generally it's about 60-70%, and the linear power is only 30-40%
All the above details are about the XIMENMG if you have any query pls do feel free to contact us.
Normal switching power supply:
100% full load burn-in test
Protections: Short circuit, over load, over current, over temperature
High efficiency, low ripple noise
2 years warranty
