UPS for POS Systems

Point Of Sale System connected to a surge protector will be protected against a jolt of electricity if there's a nearby lightning strike. But when the power goes out — even for a second — it can result in lost data and potentially a damaged hard drive.

Protecting important files and data against permanent loss due to insufficient power requires a UPS battery backup device. A UPS (Uninterruptible Power Supply) device provides both surge protection and emergency backup power. The backup power gives a computer user time (from ten minutes to an hour, depending on the device) to save critical files and properly shut down the computer until power is restored.

What is AVR?
Automative Voltage Regulation (AVR) technology provides clean electricity by increasing low voltage or decreasing high voltage — keeping it within a safe range of 110–120 volts.
Which UPS device is right for me?

   1. Point Of Sale System Standby UPS Systems

      These provide basic power protection in the form of battery backup plus surge protection. They do not, however, provide protection against brownouts.

   2. Point Of Sale System Line–interactive UPS Systems

      These are the next step up from standby UPS systems. Line–interactive systems feature Automative Voltage Regulation (AVR), which corrects power fluctuations. If the UPS detects a brownout, it draws on its battery to boost power. If it detects a surge, the UPS automatically trims power. This assures that connected equipment receives properly regulated power at all times.

      These provide the highest level of power protection. They convert incoming AC power to DC, then convert it back to clean, regulated AC. This process removes most power imperfections.

      Remember: Many UPS devices have several sockets, but sometimes only half of those will have backup power. The others will have surge protection. Be sure to connect your computer and monitor to the sockets with backup power.

      Also be sure to check which devices offer a large enough warranty for your connected equipment. Because the manufacturer's warranty will most likely be nullified in cases of damage caused by power surges, the warranty of the UPS manufacturer becomes even more important.
