You might think that battery backup systems are for blackouts. And you would be correct but did you know that OnLine UPSs (Uninterruptible Power Supplies) solve a wide range of power anomalies from sags to surges to harmonic distortion? 

By means of a robust converter, the SG Series Tower OnLine UPS takes dirty unstable AC power converts it to DC and then back to AC again. This true “double conversion” provides highly regulated output AC power that is free from voltage fluctuations and noise. The design also allows for the system to “sip” from the batteries as opposed to draining them, resulting in longer battery life and fewer associated costs. When you add in a "smart" communication ability and input power factor correction, you have elements of efficiency and intelligence to match the robust design in place to protect your sensitive equipment.

 If your system is mission critical, then its time to look past simple battery backups for a real power quality solution. Choose a real uninterruptible power supply.
