Actually the larger SmartUPS series can run for hours providing a large enough battery string is available I have a SmartUPS RM3000 running data rack this has 2 external battery boxes and will run everything for 6 hours.
For TimeNuts applications though I'd recommend a Liebert UPS as this is a 'online' UPS as in input is converted to DC and used to float batteries and drive a power oscillator for a true sine output and in a power interruption there is no transfer time or transients on the output Content by Scott Typos by Siri > On Sep 16, 2016, at 3:50 AM, Hal Murray <hmur...@megapathdsl.net> wrote: > > > g...@rellim.com said: >> APC UPS can't handle the longer runtime, but never had a problem with any >> version of CyberPower. > > There are two parameters for UPS boxes.
