The UPS offers protection from the most common electrical problems:
 Power Outages
Total loss of electrical power can be caused by various factors such as: lightning, downed power line, overloads, accidents and natural disasters. These disturbances can cause damages to electronic hardware, loss of data or a total system failure.
Sustained High Voltage
Overvoltages on the power line for extended periods of time can be caused by lightning or power line damage which increase voltage to 6000 or more volts. Such extreme overvoltages will almost always cause data loss and/or hardware damage.
Sustained Low Voltage
Sustained low voltage on the power line for periods ranging from a few minutes to days can be caused by intentional voltage reduction by the power company with the intent of saving energy during peak demand periods. Sustained low voltages can cause equipment damage. In this case, the integrated power conditioner will correct the low voltage condition.
Momentary Voltage Rises
Also known as voltage peaks. Peaks can be produced by a rapid reduction in connected loads. Such reductions can easily exceed 150% of nominal voltages. The results of these peaks may be damaged hardware and lost data.
Momentary Voltage Drops
These are momentary voltage drops caused by the starting of heavy loads, equipment failures or short circuits in the power distribution system. These drops can cause equipment damage as well as operating failures and data losses.
Noise on the Power Lines
Noise is high frequency interference due to RFI or EMI. It is caused by radio waves from a nearby radio or TV transmitting station, welding machines, printers, lightning, etc. It also introduces errors in program files as well as damage to electronic components.
Frequency Variations
Frecuency variations are changes in the power line frequency, common wherever a backup motor / generator is used. They also appear when a co-generation station is close by. They can cause erratic behavior of equipment, data losses, site crashes, as well as equipment damage.
Transients
Transients are an immediate voltage drop which may last only nanoseconds. These are very short duration voltage peaks which can cause unpredictable behavior in computer and communications equipment. They may also cause premature component failures.
Harmonics
Harmonics are a distorsion of the normal power waveform. This is caused by nonlinear loads connected to the same circuit as computer equipment or other critical loads. Motors, copy machines, fax machines, etc. are nonlinear loads that can introduce harmonics into a power line. Harmonics can cause equipment overheating, computation errors and hardware damage.
