UPS_typesWhenever power to your facility is interrupted, it can result in significant expenses and productivity loss.  These can be avoided with proper planning and an appropriate backup power system.  However, the type and amount of backup power protection needed varies depending upon the systems to be protected and the time and amount of load to be carried during the power interruption.  There are two basic types of backup power systems: uninterruptible power supply (UPS) systems and backup generators.  UPS systems are often the lowest in cost and may be sufficient in many cases, however at times it is necessary to utilize backup generation to handle critical loads.

Standby UPS or line-interactive systems monitor the incoming power and rely on batteries to correct any major voltage sags or surges.  These units provide short-term protection and are commonly used for personal computers or servers at small businesses.  However, this type of UPS system does not completely isolate the equipment from the incoming power supply and cannot protect against other power quality problems outside of the major voltage swings.  On-line UPS systems depend upon supplemental backup generators to supply power to the equipment while using incoming power to recharge the battery.  These systems use an inverter to convert the power from the battery to AC output and as long as the inverter and battery are running properly, the attached equipment will receive a steady power supply.  This type of system provides the best protection and is commonly used for loads above 10kVA.UPS_backup generator

When vital systems need protection from potential power failures, for locations without connection to the power grid or when peak periods require additional power, standby backup generators should be used.  These generators come on and operate up to the full load quickly and operate for hours, and even days, with adequate fueling.  Diesel generators are the most common although natural gas or duel-fueled generators are also available.  Generators require transfer switches or the electronics for parallel connections to operate and also require periodic starting under load and regular maintenance to ensure their reliability in actual emergencies.  They range in size and load capability from the portable 8 to 30 kVA single phase units to the large 2,000 kW power modules capable of acting as a small power station and operating an entire facility.

Regardless of which backup power option is desired, it is best to have it installed by qualified technicians.  Precision Electric has the experience and ability to install the appropriate system necessary to safeguard your facility.
