3 Power Problems A UPS performs two primary functions: Protects connected loads from the effects of mains electricity power failures by providing an instant source of backup power in the event of a mains failure. Filters and conditions mains power to protect connected loads from the effects of mains-born and system-introduced power problems associated with electricity networks. The following table gives an overview of the most common power problems, symptoms and their causes. Problem Symptoms Cause Power Blackout As the name suggests, a complete blackout and failure of the power system for over 2 cycles, which can result in system crashes, data loss and/or corruption and hardware damage Utility or mains power failure. Tripping of downstream circuit breakers. Failure of the power distribution network. Power Sags & Brownouts Short duration undervoltages (75-86% below what they should be), which last for a short duration but can cause equipment to malfunction or shut down and lead to data and memory loss, data and equipment errors and flickering lights. Large motor loads starting up. Heavy equipment starting up. Internal or mains power switching. Power Surge This is where the voltage rises above normal for short periods and can result in data and memory loss, equipment malfunction or breakdown. This can be caused by large motor loads or heavy equipment being switched off. Undervoltage An undervoltage is similar to a power sag except that it lasts for longer in duration and can cause equipment to lock up, break down and lead to data loss and/or corruption. The most usual cause of this is heavy demand for utility power. Overvoltage This is a sudden, rapid rise in voltage, the duration of which lasts for a while and can have devastating results such as data loss, equipment breakdown, burned out circuit boards and a total or partial electronic system failure. Lightning strikes. Supply faults. Power spikes A power spike is the same as an overvoltage except much higher in voltage rise (up to 6000 volts). Lightning strikes. Supply faults. Heavy equipment being switched on causing high in-rush current. Power Transients /Switching These are rapid voltage peaks of up to 20,000 volts lasting a duration of microseconds. Even though they last for less than a second, it is enough to lead to equipment damage, breakdown, data loss and component stress, which can lead to future breakdown. Utilities correcting line problems. Arcing faults and static discharge. Line Noise If not filtered out, line noise can cause system and keyboard lock ups, data loss and errors and data storage losses Electric motors, motor controls, relays, broadcast transmission, microwave transmission and electrical storms, which can result in Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI). Frequency Variations This is a change in frequency from the normal (50/60Hz). It can cause hardware to crash, data corruption and loss, keyboards to lock and software program failure. Power sources that are unstable, including generators. Harmonic Distortion Distortion of the normal sinewave waveform, which can cause hardware damage, equipment to overheat and communication errors. Switch-mode power supplies and variable speed drives. Any equipment that introduces a non-linear load transmission into the system (i.e., printers, copiers, faxes and even some UPS).

4 Complete solutions for: IT Industrial MOD Marine Retail Telecom Health The Different Types of UPS UPS are classed as either static or rotary. Within the static UPS category, there are three types: online, line interactive and offline. Online UPS (also known as VFI Voltage and Frequency Independent) This type of UPS continuously powers the load through its inverter, creating a break-free supply in the event of a mains failure. It employs doubleconversion technology to convert the voltage twice, from mains ac to dc, using its rectifier, and from rectifier dc to ac using its inverter), which enables voltage and frequency levels to be tightly regulated. This type of UPS continuously conditions power to ensure loads receive a clean, problem-free supply. Newer designs of online UPS offer several operating modes in order to improve economy and reliability. This type of UPS typically ranges in size from single 700VA units to 800kVA modules, the larger of which can be employed in parallel configurations to build in redundancy. Line Interactive UPS (also known as VI Voltage Independent) This type of UPS is a step up from online designs and offers enhanced power protection and additional line conditioning. When mains power is present, UPS output is supplied via a built in Automatic Voltage Stabiliser (AVS), which operates within a set input voltage window. An EMI/RFI filter is employed to protect the AVS and load by clamping peak voltages to acceptable levels. When mains power supply fails, the inverter is powered up and a relay connects the load to the inverter output. Line Interactive UPS have internal battery sets that provide a short duration runtime at full load. Runtime can be extended with the connection of external battery extension packs. Offline UPS (also known as VFD Voltage and Frequency Dependent) This type of UPS offers basic power protection, some line conditioning and filtering and is used primarily for small, essential loads (such as work stations, terminals, PCs) below 1kVA. When mains power is present, UPS output is supplied via a built in EMI/RFI filter that provides limited protection from spikes and transients. A simple charging circuit charges the internal battery. The inverter is usually in offline or standby mode. When mains power fails, the inverter powers up and a relay connects the load to inverter output. The internal battery within and offline UPS offers 5-7 minutes of back up power and there is no facility for adding runtime extension. This gives enough time, however, in the event of a mains failure, to gracefully shutdown equipment and spare it from damage. Line Interactive and Offline UPS do not provide a break-free supply like Online UPS does and this makes them unsuitable for some types of sensitive load. Rotary and Flywheel UPS Rotary UPS and flywheel UPS are mechanical devices that convert kinetic energy into electrical energy using a rotating transformer, induction coupling or a flywheel engine. They usually start at 500kVA in size and can range in excess of 2MVA. Coupled with the fact that they typically carry a high capital outlay cost, they are designed primarily for very large installations. The advantages of these technologies are that they generate little in the way of harmonics, offer a very high meantime between failure (MTBF), have better fault clearing capabilities and can cope with leading power factor loads, such as high-end Blade servers of the type used in data centres. In the right setting, and for the right application, they also offer greater operating efficiency, higher reliability and lower lifetime costs compared to equivalent static UPS designs. Modular UPS Modular UPS is a relatively new phenomenon that allows for better right-sizing of UPS systems. Several leading manufacturers such as EATON and Riello UPS now offer modular UPS systems. Historically, UPS has had to be oversized in order to build in redundancy (using parallel configurations) and to allow for future system expansion, and this has resulted in each unit within the system running inefficiently. The call for efficiency, particularly within the data centre community, is loud and clear and so modular UPS now enables UPS systems to be right-sized and to run efficiently while capacity and increased redundancy can be introduced incrementally. Small units of 12-15kVA (depending upon UPS brand) can be stacked or slid together using a drawer-style approach within a standard data centre rack. Each 12 or 15kVA unit is an independent UPS in its own right with all of the associated internal workings to enable it to operate independently if required. However, several units (6-8 per rack) can be run together to provide increased capacity and redundancy. Some modular designs enable multiple racks of units to be paralleled together for further capacity. Modular UPS carries a higher capital outlay but because it enables more accurate right-sizing is gaining ground in applications (such as data centres) in which progressive growth is anticipated but impossible to predict.

5 UPS Applications The UPS market has opened up in the past few decades and continues to do so as more and more businesses and operations rely on electrical equipment for their very continuity. If you think about it, everything we use at work these days needs to be plugged in somewhere even if it s just to recharge a battery. The good news is that this opens up a whole raft of opportunities for us and our trade partners and we are all geared up to help you make the most of it. In any situation where a power loss or poor power quality will result in business disruption, data loss or corruption or a breach in safety, some form of power protection and alternative power source is required. The most common form is UPS power protection alongside an onsite diesel generator, both of which can be paralleled (two or more UPS and generators operating together making up and parallel configuration power protection system) to offer extended runtime and redundancy. Below are outlined some common applications for UPS power protection: Computers Many businesses rely on computer systems today. Some, such as data centres, sell hosting to customers and have to ensure specific levels of uptime and availability. This category of application also includes file servers, telecoms and communications equipment such as network servers, switches, routers, PBXs and so on. Financial Systems Such as those that run and operate retail EPoS (Electronic Point of Sale) terminals and ATM (Automatic Teller Machines). Industrial Equipment that runs industrial processes, pumping equipment and so forth, plus medical machinery and life support systems. Security/Entry Systems Door entry systems (access control) are often controlled electronically and if the power goes off they will either open (thus creating a potential security breach) or stay locked (thus creating a safety issue for the people within). Other systems that fall into this category are CCTV, automatic gates and car park barriers. Safety Emergency lighting, lifts, public address systems. Remote applications Rail signalling equipment, remote telecoms equipment, unmanned safety and communications systems, broadcasting equipment and monitoring systems.
