The load is a 150 (standby) ~ 350 (full load) of the desktop plus a 40W monitor, but would like to power after a long period of time, normal use (do not play the game, is to browse the web) the best over 1 hour, 2 hours better, I should probably choose what kind of UPS, which brand will be better? There is power when there is no noise, electricity and charging time must be quiet. The The White asked the great gods. The The Thank you.
UPS noise is usually no more, only when the use of noise. UPS is not particularly afraid of dust, only when the fan began to turn.
General UPS configuration to the following formula:
UPS power supply (VA) × delay time (hours) ÷ UPS power supply DC = required battery safety hours (AH)
To Hills C3KS delay 2 hours as an example we have to calculate the following: Note: Mountain C3KS start DC: 96V
400 volts x 2 hours ÷ 96V = 8AH
The result is the need for 8AH battery to meet the 2 hours of power supply, (because C3KS start DC is 96V- (UPS in the factory when the standard DC voltage) General battery mostly 12V DC, 96V (UPS start DC voltage) ÷ 12V (battery DC voltage) = 8 So, (with 8 10 batteries as a group) battery on the line.
