For example, let\u2019s say that my system draws a maximum of 30 amps at 208 VAC. Using this <a rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/www.rapidtables.com\/calc\/electric\/Amp_to_kVA_Calculator.html\" target=\"_blank\">kVA calculator<\/a>, I come up with 6.24 kVA, which means I would need a UPS with a rating of at least 6.24 kVA. The higher the kVA rating, the higher the cost of the UPS.<\/p>\n\n\n\n<p>There are three other things to consider for the kVA rating.\n<\/p>\n\n\n\n<p>The first consideration: What is the main breaker on the system rated at? On older Physical Electronics XPS and AES systems, the main breaker ranges from 30 amps up to 60 amps depending on the type of system. A 60-amp 208V kVA calculation comes out to 12.48 kVA.<\/p>\n\n\n\n<p>The second consideration: What is the actual current draw of the system? Usually, this is much lower than the main breaker current rating. For example, a PHI 5600 XPS system may have a 50-amp main breaker and a kVA of 10.4, but the actual maximum current draw might be only 20 amps (during a bake-out), which comes out to only 4.16 kVA. So, technically, a 4 kVA UPS would be adequate for a 5600 system, <strong>except<\/strong> that most electrical codes require that the power connection to the system is rated higher than the main breaker. This means that a 50-amp main breaker system would need a 60-amp 12.48 kVA connection to the system.&nbsp; <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img data-attachment-id=\"3044\" data-permalink=\"https:\/\/www.rbdinstruments.com\/blog\/surface-analysis-systems-and-unstable-line-voltage\/ups-connected-to-system\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=834%2C588&amp;ssl=1\" data-orig-size=\"834,588\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"UPS-connected-to-system\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=300%2C212&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=584%2C412&amp;ssl=1\" decoding=\"async\" loading=\"lazy\" width=\"584\" height=\"412\" src=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/plugins\/jquery-image-lazy-loading\/images\/grey.gif?resize=584%2C412&#038;ssl=1\" data-original=\"https:\/\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg\" alt=\"\" class=\"lazy wp-image-3044\" srcset=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?w=834&amp;ssl=1 834w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=300%2C212&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=768%2C541&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=426%2C300&amp;ssl=1 426w\" sizes=\"(max-width: 584px) 100vw, 584px\" data-recalc-dims=\"1\" \/><noscript><img data-attachment-id=\"3044\" data-permalink=\"https:\/\/www.rbdinstruments.com\/blog\/surface-analysis-systems-and-unstable-line-voltage\/ups-connected-to-system\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=834%2C588&amp;ssl=1\" data-orig-size=\"834,588\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"UPS-connected-to-system\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=300%2C212&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?fit=584%2C412&amp;ssl=1\" decoding=\"async\" loading=\"lazy\" width=\"584\" height=\"412\" src=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=584%2C412&#038;ssl=1\" alt=\"\" class=\"wp-image-3044\" srcset=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?w=834&amp;ssl=1 834w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=300%2C212&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=768%2C541&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2020\/11\/UPS-connected-to-system.jpg?resize=426%2C300&amp;ssl=1 426w\" sizes=\"(max-width: 584px) 100vw, 584px\" data-recalc-dims=\"1\" \/><\/noscript><\/figure>\n\n\n\n<p><strong>Before installing a UPS<\/strong>, refer to your local\nelectrical codes because you may need to get a permit or have the UPS installed\nby a licensed electrician. <\/p>\n\n\n\n<p>The third consideration: Do you need a battery backup or\njust a line conditioner? A line conditioner costs much less than a UPS with\nbatteries, and batteries also require maintenance and occasional replacement.\nBatteries in the UPS provide backup power to the system.
