What types of equipment can benefit from UPS?
Any kind of computer-based system will show improved performance when protected against noise. As an alternative to a dedicated line, the LEXSUNS UPS provides a portable solution in applications such as telecommunications systems, Information systems, retail information systems, computer integrated manufacturing systems, semiconductor manufacturing and test equipment, biomedical instrumentation and information systems and more.

What causes electrical noise?
Electrical noise can be caused by major disturbances like lightning, but is most often the natural by-product of the use of electricity. For example, noise that gets into your instrument can be caused by the air conditioner in your building, refrigeration compressors, the emergency generator set, laser printers or even neighboring electronic systems. No matter where you plug in your equipment, you find electrical noise. In fact, it's only safe when it's unplugged or protected by an LEXSUNS UPS.

I don't have any power problems. Why do I need a UPS?
Electrical noise is truly an invisible problem since the damage it does may not cause your system to fail immediately. This unseen damage frequently causes "soft" failures, such as those unexplainable errors in printing, system lock-up or inaccurate test results. Ultimately, the cumulative effect of these problems will show up as hard failures. And that means your system stops working and requires repair.

What benefits will I see if I use an LEXSUNS UPS?
You will see a dramatic decline in failures of all types. Your equipment will run more smoothly. You will experience fewer random errors, fewer instances of of lost or garbled datas and fewer outright equipment failures.

Why is LEXSUNS the best UPS product I can buy?
LEXSUNS is the only UPS that was designed with the new generation of computerized equipment in mind. The designers at POWERSOS thought through all of the issues concerning the effects of electricity on sensitive circuitry and designed a product that protects your system at all times, even when you are not using it. LEXSUNS has been extensively evaluated and recommended by the major manufacturers and users of retail systems. Some special features that distinguish LEXSUNS UPS from competitive models are: greater efficiency, quieter operation, much less heat generation, smaller size, clean.

Why don't electronic manufacturers build this protection into their systems?
Some level of protection is built into most systems. However, since electrical noise levels vary dramatically from location to location, and there is considerable pressure to keep equipment price levels down, manufacturers usually build in a lower level of protection. In effect, it's up to the user to provide the proper environment which includes clean electric power.

Do I need an electrician to install an LEXSUNS UPS?
Except for some of the larger models, LEXSUNS units do not require any special wiring. You only have to plug the units into the existing outlets.

How long will my LEXSUNS UPS last?
All POWERSOS-manufactured products come with a 3-year parts and labor warranty. Because of the design of the product, we have every reason to believe that they will last considerably longer than the electronic equipment they protect.

Are there any products available which cost less?
Yes. Any computer store or catalog can sell you one of the many low cost surge/spike protectors. They go by many names: surge suppressors, spike arrestors and MOVs. These low cost products were originally designed to protect devices (such as your TV) from damage during a lightning storm. Generally, they have many similarities, some of which, unfortunately, are harmful to electronic equipment. For example, surge protectors often cannot filter out spikes of several hundred volts and can actually wear out or fail without you knowing it. They also sacrifice any ground noise protection for acceptable leakage current levels. In summary, they provide limited protection at a low cost.
