![]() ![]() If the AC sine wave is rough, some computer power supplies will whine or even be damaged by the rough current. ![]() We recommend Line-interactive units.Īs AC wall power reverses smoothly 60 times per second, UPSes must produce a smooth sine wave to mimic this from the DC powered battery. Line-interactive models have AVR or automatic voltage regulation, that cleans incoming current without switching over to battery, so they last longer due to less wear on the battery. Standby units during surge, sag or brownout conditions, they switch fully over to battery draw. There’s two types of UPS- standby, and line interactive, both can switch over in the case of power failure in a few milliseconds. USB connectivity can tell your computer the remaining battery time, and trigger a shutdown through software. UPSes usually offer half their sockets as battery and surge protected, the other half being just surge protected. How does a UPS work? Installed between a properly wired and grounded socket and your devices, the UPS battery charges and remains topped off, and during a brownout or blackout, the battery kicks in, delivering power to all battery-side connected devices until the battery is exhausted. And lightning’s common in Taipei from the tropical weather, having extra protection for our data is the main reason we bought one. They also help mitigate spikes from lightning strikes which is the Joule rating on surge protectors. No matter where you live, you’ll get voltage surges, sags and brownouts depending on the demands of the power network around you, even in your own home, from turning on an old fridge or A/C unit, which can really put a spike in the voltage. ![]() At minimum, it saves you time recreating lost work or fixing drive issues, even if your hard drive/SSD or hardware survives intact. If you’re a PS4 owner, you know about that 2 to 3 minute wait while your console becomes operational again! Protection from data loss is important too, if your PC suddenly loses power you can get corrupted documents, or a badly timed windows update could leave you having to reinstall windows again. There’s two areas we’re looking at, keeping your network up, and preventing computers or even game consoles from abruptly turning off. You can keep your network online if it’s essential, keep a PS4 or Switch and TV on during a power failure, or have your main PC and monitor on battery backup so that you can save and power down safely. Bigger wattage batteries give longer run times, and newer UPSes provide surge protection. UPSes are rated by VA and watts- watts equals volts times amps, often referred to as VA or Volt-amps. These are Standby models, so a Line-interactive mini-tower CP1000AVRLCD 600 watt for 120 bucks should get you past the 3 and a half hour mark.Ī UPS or Uninterruptible Power Supply kicks on if the power goes out, powering whatever is connected to the battery side. Around 500 watts with LCD for 100 us, 80 on sale, network stays up just under to 3 hours. A two minute summary: for a network, at minimum get a 250 to 300 watt backup, with no LCD goes for 50 us and lasts an 1 hour 20 minutes. TLDR- after testing and research on models and performance for price, pick a UPS with an LCD screen, 500 to 600 watts minimum, and USB connectivity. We’d recommend getting a separate surge protector power strip if you’re safeguarding heavy demand devices.įinally, to maximize battery runtime during a brownout or blackout, only battery backup your absolutely essential equipment. Number four, don’t plug a laser printer, paper shredder, copier, space heater, vacuum cleaner, pump, compressor, or power hungry devices like hairdryers into the Battery and Surge Protected Outlets. You also can’t use it for aquariums or on any transportation as condensation or vibration can cause a short. Third, don’t connect power strips or extensions into either the battery plus surge or just surge protected UPS outlets, as it increases the risk of electrical fire. The surge protection features won’t work if it’s not properly wired and grounded, and you won’t be covered by any Connected Equipment Guarantee. If it’s on, you need to check your outlet to make sure it’s correctly wired and grounded. First let’s start this UPS Buying Guide with a Quick Tips section.įirst, to ensure the battery’s maximum charge capacity, it’s recommended that you charge the battery for at least 8 hours, some manufacturers and higher capacity models may require a different amount. Thx to “RB Inc” for the info~! More info on CyberPower’s pageĪre you looking for battery backup? What kind of features are you looking for in a UPS? Please leave your thoughts in the comments. NOTE: A PFC Sinewave model is REQUIRED if you have a smart-type power supply that has Active PFC. ![]()
