GTIS Power and Communications Systems
Description
What this product does: Use this when you need a UPS that can run for more than half an hour or if you want better protection from surges coming down the power lines. Combine with one or more large 12-V, deep cycle batteries, sold separately, to make a long-running uninterruptible power supply (UPS) for powering computers or network equipment during power outages. Your loads are always powered by the pure sine wave inverter for excellent isolation from AC line surges noise and voltage fluctuations. AC line power is used to charge the batteries when it is available.
Recommended use(s): Perfect for powering your NAS server and network switches through long power cuts. The 15A version can power a desktop computer system or up to three laptop computers. Although the inverter can power 300 watts continuously, the battery charger can’t keep up with that. Choose the 15A charger option for less than 120W continuous loads, and the 30A option for continuous loads up to about 280W. The higher your loads, the longer it will take to recharge the batteries after a power outage.
Batteries required: Any lead acid battery over 50 Ah will work with the AC Power Hub, but “deep cycle” batteries will last longer and are worth the extra cost. GTIS recommends Outback Northstar AGM batteries as the most cost effective due to their extraordinary cycle life. A 100-Ah AGM battery will power a laptop computer and a small florescent light for over five hours.
Estimating Runtime: The inverter is pre-programmed to cutoff when a Lead-acid battery is depleted about 50%, so available energy is 50% of the Amp-hour rating of your battery multiplied by 12v. For a 100Ah battery that comes to 600 watt-hours. Divide 600 by the average power draw of your equipment ( in watts) to estimate the hours of run time. For lithium batteries, use 90% of their rated capacity.
Advantages of this product: Extra lightning and surge protection! This UPS is always running from 12V DC, so none of the dirty power from your AC power company gets passed through. The built-in Morningstar SureSine inverter has no internal cooling fan or other moving parts prone to failure.
Additional notes: The Standard model has a Euro CEE 7/7 plug for charging and a CEE 7/5 socket on a short cord for connecting the load. You may include a note when you order if you would like instead a British BS 1363/A plug for charging and a BS 1363/A socket on a short cord for connecting the load.
