| Where do I get the information regarding the voltage and amperage load of my system, to buy the appropiate UPS backup system.
Thanx

| I'm assuming that you are referring to UPS sizing. Here is a link to APC. They have a lot of good info for sizing a UPS. Rule of thumb says buy as much capacity as you can afford (the bigger the better).

| Super.. what I meant to say was "I am a computer technician and a client wants me to sugest him a UPS with the capacity to cover the needs of his personal computer in the case of an electrical emergency. Where do I get the information of voltage and wattage for that particular computer to give him an accurate recomendation in the field" Maybe it's a silly question or I don't know how to phrase correctly...BTW I checked the link you gave me but I was looking for something more practical for a "field technician" something like: "multiply this info here by that one right there, plus add 20% and presto!!" if You know what I mean..
Thanx in advance...

| I don't understand. Configuring an UPS is not that simple. Most everyone that I know uses the link that Supertech gave you. If you just want to pick a PC then use 400 watts plus the label on the back of the monitor. Don't include printers as you should never hook them to the UPS. Next ask the customer how long he or she wants power for, i.e. long enough to shut down, long enough to keep working for 15/30/45/60 minutes? What else needs protecting, hub, switch, router, modem basically any non-high current motor driven devices. Then take that info back to the APS link and it will give you a wealth of info. | |

| Jose,
Did you even look at the link I provided? If you cannot size a UPS from that site, just give the link to your client because if they can use a computer, they can figure it out by themselves.
How does the UPS Selector work?
The UPS Selector determines the power draw of your equipment by interviewing you about your system and then drawing upon an extensive database of actual power measurements for equipment and peripherals. In addition, the UPS Selector has a database for actual power consumption of computer components such as processors and disk drives. This allows the UPS Selector to determine your load power requirement. The UPS Selector requests your preferences for run time, room for growth, and specific features you want. The UPS Selector has a mathematical model of every APC UPS that describes the product limitations and the run time of the UPS vs load. Using all of this information the UPS Selector can solve for the APC products that best match your requirements. The UPS Selector is even smart enough to assemble combinations of APC products including battery packs and other accessories to match your needs. | |
