Before
make a purchasing power supply decision, do you consider power
efficiency and size? higher efficiency can save energy and electric
charge, at the same time smaller size not only easy to take but also
save more shipping cost.
As far as large power of 1200W, efficiency and size is more important than small and middle power adapter.
Efficiency=Pout/Pin*100%, Pout=Vout*Iout
for S1200, Pout=24V*50A=1200W
If efficiency=94%, means consumptive energy is 72W---1200×(1-0.94); if it is 85%, it will be 180W.
Active PFC will improve the enery consumption from main power grid evidently.
For ouput 1200W power supply, if averarge efficiency is 92%,
PF is 0.99, the energy from power grid is 1200/0.92/0.99=1317.5W,
if efficiency is 85%, PF=0.7, the energy is 2016.8W. the
surplus 699.3W (2016.8-1317.5) will be wasted as heat, and increase the
power grid load.
S1200 - 24V 50A - programming digital
power supply is released now, optimize design repeatedly in past 14
months, the power supply reached up to 94% at 60% of load and AC220V,
ultra low power consumption make sure its internal temperature under 60?
and realize components' performance.
Active PFC, Synchronous Rectification, ZCS and ZVS full bridge topology applied to powerful S1200.
