S400 is one of PFC power supply S series, high efficiency and wide input voltage range, large scale output voltage adjustment, and smaller size. S400 can output 15V 25A 400W at AC100V~240V, and the internal temperature is still under 75°C.
V2 now with better power switch.
The following are many new features:
Active PFC: smaller AC input current less interference, and Conform to European Commission Regulation no 278/2009 and Energy Star Version 2.0
AC100-240V worldwide use: need not any alternative switcher, worldwide safe operation
Up to 92% of convert efficiency
Programming output voltage from 6 to 15V, suitable for more application
Digital display output voltage and current on time
Over current, over voltage, over load and over temperature protection, and resume automatically
Short-circuit protection on output, safer and more reliable
Intelligent cooling fans turned on at over 45?
2 outputs can do more chargers simultaneously
Synchronous Rectification make sure the high efficiency and smaller size
Start at no load or full load perfectly
