I recently bought a Legrand UPS model Niky 600 model (UK/EU voltage). It is rated at 600va and 300W. It has 1 IEC AC input, 4 IEC load outputs, a USB port (for diagnostic and other stuff) and telephone in/out sockets.
Before purchase, I checked APC's UPS selector to see which model I needed to keep a cordless phone (5.5v; 500mA) and a ADSL router (12v; 1A) on during a power cut. According to APC selector, a 500va UPS would give me 202 minutes.
So my thinking was that Legrand's Niky 600va would give me at least that amount of uptime. Instead the UPS is shutting down at exactly 60minutes during a simulated power failure (switch off AC to the ups). UPS was charged for more than 10h before conducting my test. Did it twice and same result. Any thoughts or solutions most welcomed. Thanks.
~ ~ So far I managed to install Legrand's UPS Communicator software to communicate with the UPS via its USB port. All diagnostics run fine. It doesn't report any errors which is what you'd expect from a brand new device. During simulated power failure, the device was making an annoying beep every 3 seconds. I used the software to switch off the UPS buzzer as they call it. So that's good. Also good is that the diagnostics reported that my phone + ADSL only represented a 2% load on the UPS and its inside temperature was a constant 30ºC.
That UPS is rated to give 5 minutes of uptime at 80% load! So shutting down at exactly 60minutes during power cut at 2% load just doesn't make sense to me. In the software configuration options, I disabled everything which has the word "Shutdown System" or "Shutdown UPS" next to it. But this has had no effect during my second powercut test. ~ ~
