Tips: Switching power supply characteristics and applications
SMPS Main characteristics:
- Small size and weight: the size and weight of switching power supply proves to be 20-30% of linear power, because it has no industrial frequency transformer.
- Low energy consumption and high efficiency: power transistor operates in switch state, so it presents lower energy consumption and higher conversion efficiency with a conversion rate of 60-70%. As a contrast, linear power supply only presents a conversion rate of 30-40%.
SMPS Applications:
Switching power supply is widely applied to industrial automatic control, military equipment, R&D equipment, LED lighting equipment, industrial control equipment, communication equipment, power equipment, meters, medical equipment, semi-conductor refrigeration and heating equipment, air purifiers, electronic refrigerators, LCDs, audio-visual products, security and monitoring devices, LED strip lights, computer cases, digital products and various instruments.
Switching power supply converts full range AC to DC 12V, rated current 8.5A and rated power 100W, with overvoltage and overload protection. High quality and high efficiency SMPS power supply suitable for light strip, computer, printer, industry control system, and home appliances.
