• What is digitized power?

This is the way of the future. Today we digitize music, radio and satellite signals and even our TV. The advantage is that the signal can be processed at remarkably high rates, enabling faster response and virtually no distortion. The result in digitized power is an output for the critical load that is rock steady and without any unwanted distortion as well as no THD reflected to the source. The time to correct for load pick-up or full range input voltage deviations or just straight up power failures is in the 4 to 8 micro second range! No more 7 to 10 millisecond response. Loads with the new approach of digitized power receive clean, steady, deviation-free power 100% of the time.




• What is a PFC and its importance?

PFC (Power Factor Correction) is a method of correcting the displacement power factor for loads that exhibit non-linear current characteristics (almost all of them). Some PFC power supplies ignore the harmonic distortion reflected back to the power source or do very little to correct for the harmonics generated. The proliferation of computer loads within a centralized location will eventually show their teeth. Circuit breakers trip, power wires heat up, some burn, and the sum of all the distortion produced by the loads will affect the operation, life and performance of equipment throughout the building. Meeting today's THD harmonic standards as well as knowing your equipment is operating in the best electrical environment is crucial to longevity and performance of electronic equipment. Using a UPS with a PFC that attenuates harmonics to 5% or less and corrects the power factor will take you well into the future without any worry. The UltraUPS offers this combination of performance features and reliability for the 21st century.




• What is a Dual Phase UPS?

Dual phase operation is defined as a single source operating as two independent sources with a common neutral. As an example, a 208 three phase source is three independent 120 volt sources with a common neutral. The UltraUPS takes advantage of this within its regulator circuits. It regulates and processes each phase independently while maintaining the phase relationship of the source. The output voltage regulation and digitized re-creation of the sinewave is an independent process. The result is that the output can be 208/120 volts single phase with the same phase relationship of the three phase source. This is important for bypass systems because it provides the means to perform seamless make-before-break operations.




• What is meant by a cluster?

A cluster is a group if peripheral devices all connected to a common UPS power source. This is the preferred method. It provides the means to maintain a common ground, establish common mode attenuation (suppress ground noise) and centralize the back-up operation. Independent UPS's for each peripheral becomes a battery management nightmare. Not knowing which one is working or if they produce the same back-up time becomes a serious concern. Having one source for all the peripherals assures that the battery time is the same and that only one ground is used throughout. Also, it is so much easier to incorporate one power conditioning transformer as compared to many little ones. If your plans indicate growth in the future - plan for it with a UPS that offers the ability to cluster your equipment and adopt to change.




• What is a double conversion UPS and why is it the preferred choice?

A double conversion UPS is one that continually recreates power for the load from a DC source. The input AC power is converted to DC and passed to an inverter that converts the DC back to AC. The battery is connected directly in the middle, such that if AC power were to fail, the battery would continue to support the load without any switching or transition. This is in contrast to line interactive systems where the power is not processed but just passed on to the load. In the event of a power failure the battery must be switched in. The stand-by inverter must now carry all the load at once and is the most susceptible at the time of failure. On some line interactive systems, if operating on AC power, no conditioning or regulation is provided. A double conversion provides continuous regulation, power conditioning and auto bypassing during the time of overloads, a PM or repair. Double conversion offers double protection.




• What is Fuzzy Battery Intelligence?

This is an advanced technique of managing the battery system within the UltraUPS. Fuzzy Battery Intelligence incorporates fuzzy logic, a computer logic that uses an array of acquired battery information to make decisions for the exact amount of charge and correct usage of the batteries. It affords the longest run times possible from the batteries, sets the recharge at an optimum rate and prolongs the life of the batteries well over conventional menthols. Fuzzy Battery Intelligence actually thinks; providing the battery system the information needed to acquire the best possible performance.




• What is the nemesis of Maintenance Bypass Systems

Maintenance bypass systems are an absolute necessity in any critical computer operation. They provide the means to supply power to the loads when maintenance or repair is required. The key to the correct bypass system is the ability to transfer the load to an alternate power source without disruption; that requires a Make-Before-Break switch. This style of switch connects the alternate source to the load before it removes the UPS power, the load sees no interruption. Another important aspect is that it also switches the neutral as well. Most simple bypass systems omit this function. If the neutral switching function is omitted then all the required FCC EMI and RFI circuits are short circuited; allowing the UPS to emit harmful interference and RF radiation into the surrounding area. The UltraUPS unique system provides a Secure bypass system. It acknowledges synchronization of the power sources, uses a third switch element to break the neutrals, includes the distribution within it's switch circuitry and is a make-before-break.




• How important is Voltage Regulation?

Electronic equipment is designed with a optimum center voltage of operation. Deviations from this nominal voltage are tolerable to some plus and minus values. The farther away from nominal the greater the chances of early failure and intermittent interrupted operation. Some UPS systems consider regulation as far out as 135 volts to as low as 104 volts. ( This is not regulation nor is it good practice to allow this much deviation) A good practice is no more than 3% deviation and any thing better than this is a great improvement. When evaluating a UPS, don't just accept the broad statement that regulation is provided; make sure it regulates both on line and on battery and keeps the voltage within 3% or better 100% of the time.




• Do all UPS systems provide power conditioning?

Not a chance. Some manufactures add TVSS and call it power conditioning. Although this is a good start, it only offers limited protection and does nothing for ground noise. Ground noise or common mode noise can only be addressed with a power conditioning transformer. Some manufacturers don't even supply this as an option! If you are serious about having the system for back-up and protection then get serious about power conditioning, ask for it. A properly coordinated power conditioning transformer isolates your load from the utility, eliminates ground noise, and provides your equipment with a newly derived central point ground.
