Posted by: wankel Posted on: 2002-02-27 12:21 dear U need a calculation. UPS is count @ KVA hours. all eqshould be 220V, then most is 1A to 2 A, If U need 1A + 2A +2A =total 5A * 220= 1.1KVA. Then 1.1KVA hour is your model. Battery is the exten the time. :) | |

Posted by: iczfirz Posted on: 2002-02-27 12:28 我錯我錯.. 係VA (voltage x Amp)先岩.. 有時都會用W(watts)表示.. 但VA不等於W.. 你會係鴨記華輝見到呢個牌字.. 但未必係呢個型號.. http://www.opti-ups.com/products/backup_time.htm 俾個例子你.. 一個普通315W UPS 可以頂到31.5W 十個鐘.. 可以頂eheim 1250 1200L 28W水泵 十個鐘多d 亦可以頂到一支300w暖管開足一個鐘勒.. 我自己冇用.. 我玩過果D係是但一部都貴到可以做買樓首期既.. DataCenter用個種.. :D | |
