This passes "unplug/replug UPS - computer stays on test" - where a CyberPower failed.
I bought this UPS to go with a mini PC I have. The PC doesn't have a battery. As a test, I unplugged the UPS, and the PC stayed on. I plugged the UPS back in, and the PC kept running as expected. I initially bought a CyberPower CP850PFCLCD 850VA Sinewave UPS. My PC would would turn off when I plugged the PC back in during this test, and it was repeatable. The monitor stayed on, with no visible power cycling. I got a refund on the CyberPower - as the point of a UPS is for your computer to stay on during an outage (!!!). I initially chose the CyberPower for the sine wave, easily replaced battery, and digital display.This is a line interactive step-approximated sine wave system. The manual says the transfer to battery delay on outage is "6ms typical, 10ms max." The manual says the stepped sine wave is appropriate for computers and peripherals and "is not intended for motor driven equipment," and the input power may be rejected (no mention of any associated hazard). This is fine with me.I actually prefer (a lot) the simple operation of this unit compared to the CyberPower. I don't need all those extra settings the CyberPower has, which I realized when I stepped through them at installation. With the APC, you just charge it for 10 hours, and then plug it in and go. The APC is also smaller (6 3/4" tall vs. 9 1/2"). The APC has a voltage sensitivity setting (low/default) for noisy (voltage range) input voltage, for use with equipment not sensitive to this fluctuation, to avoid switch overs to battery, which shortens battery life. I left it on default, and there have been no switch overs. When I unplug the UPS (power outage) there are initial warning beeps, followed by 4 beeps every 30 seconds. You can mute those beeps with a short press of the power button, and you won't get more beeps until the battery level gets critical. The beeps aren't too loud, and I'll probably leave them going during an outage. There is optional software to control the UPS, which I haven't tested and don't need.Ver másVer menos
