Pls advice me if the an LCD,home theatre,DSTV and a video be powered comfortabily by a 650va ups?I'm almost in doubt.And is it proper to use a ups on a stabiliser?someone said it to protect the ups.

No!


Home theatre at 250W (+power factor + losses = 370VA)
LCD at 280W (+pf + losses = 400VA)
DSTV at 70W (+pf + losses = 120VA)
video at 100W (+pf + losses = 150VA)

Total = 1040VA minimum thus you need about 2kVA ups.


NB: These power estimates are just the minimum you can get for these devices. Post the real power consumption for these devices and I will render more assistance.


@Mods: move this thread to the geeks' section.

It aids the ups by providing better voltage regulation. Nevertheless, a ups is inherently a stabilizer as well. Thus, havin ups + sab is equivalent to sab + sab except for the backup power supply provided by the ups.
