3 Top Uninterrupted Power Supplies (UPS)

It is a no-brainer that computers required power to operate, but not many people consider getting an uninterruptible power supply (UPS) to protect against power loss.  A UPS activates instantly during a power outage and keeps your computer up and running even though the whole house may be in darkness.

Depending on the unit, a UPS can give enough time to finish your project, or same your work and shutting your computer down properly until primary power is restored.
Here are three UPS units that are worth looking at.

The APC Smart-UPS is powerful enough to protect your servers, switches, routers and networking devices. The SMT1500 not only provides backup battery power in the event of a power outage, it also monitors and protects your equipment from harmful power conditions, spikes and surges.
It has an automatic green mode that ensures you are operating at the highest level of efficiency, while intelligent battery management maximizes performance. With a 1,000-watt power capacity, eight battery and surge protected outlets, and one switchable outlet group, this Smart-UPS is ideal for small to medium-sized businesses.

The Sinewave PR1500LCD mini-tower UPS with line interactive topology is design to support all types of equipment. It provides battery backup, power protection (using sine wave output), and surge protection for corporate servers, department servers, storage appliances, network devices, and telecom installations requiring Active PFC power source compatibility.

The PR1500LCD uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently. Another important feature is the patented Green Power UPS advanced circuitry that reduces energy costs up to 75% compared to the competition.

The Smart 1500LCDT will provide battery back-up for an energy-efficient desktop computer and LCD monitor (75 W load) for up to 90 minutes during an outage. At half-load (450 W), this UPS will provide run-time for up to 10 minutes. That should be more than enough time to save you files and shut your system down properly.
It features an LCD screen that reports real-time UPS and power status. An Automatic Voltage Regulation (AVR) corrects under-voltages as low as 92V and over-voltages as high as 150V without drawing battery backup power.
