New
generation PFC power supply is avaialbe. Active PFC, Synchronous
Rectification, ZCS and ZVS full bridge topology applied to powerful
S1500. higher efficiency can save energy and electric charge, at the
same time smaller size than S1500 not only easy to take but also save
more shipping cost.
Optimization of system design make sure
the 1500W power supply consume less than 1W at idel mode. TFT color LCD
is easy to display clearly voltage, current, output power and internal
temperature.
Advanced four button design easy to operate and control your power supply.
The output voltage and current is controled and measured by ARM mcu, it is more accuracy.
Although S1500 can output 1500W, the
efficiency is still up to 94% at a smaller size than S1200 and only with
2 lower noise cooling fans.
Efficiency=Pout/Pin*100%, Pout=Vout*Iout
for S1500, Pout=25V*60A=1500W
If efficiency=94%, means the input power is 90W---1500×(1-0.94); if it is 85% for other brand, it will be 225W.
Active PFC comparation with passive PFC will improve the enery consumption from main power grid evidently.
For ouput 1500W power supply, if averarge efficiency is 92%,
PF is 0.99, the energy from power grid is 1500/0.92/0.99=1646.9W,
if efficiency is 85%, PF=0.7, the energy is 2521W. the
surplus 874W (2521-1647) will be wasted as heat, and increase the power
grid load.
S1500 - 25V 60A - programming digital
power supply is released now, optimize design circuit make sure ultra
low power consumption and low internal temperature under 60? and imrove
components' reliability. |
