What Power Problems can arise? Surges, Sags, Under & Over Voltages, Line Noise, Switching Transients, Harmonic Distortion, Frequency Variation and even complete Power Failure are the nine most prevalent 'Power Problems' which can affect the normal operation of any piece of electronic equipment....... Find Out More about this topic ...... What is a UPS? An Uninterruptible Power Supply is a device that sits between a power supply (e.g. a wall outlet) and a device (e.g. a computer) to prevent undesired features of the power source (outages, sags, surges, bad harmonics, etc.) from adversely affecting the performance of the device - plus - sufficient electrical autonomy to either shut systems down or switch to other alternative supplies (eg: generators). The electricity utility companies supply alternating current from the mains to direct current. The UPS is a buffer battery which is placed between the mains connection and the computer. It converts the alternating current from the mains to direct current to charge the battery, then reconverts it to alternating current to supply the computer. UPS features can also be enhanced by means of communications software linking it with various network and administrative platforms Are there different types of UPS? Not every UPS protects against all power problems. There are usually 3 levels of power protection to choose from being Off-Line (StandBy), Line Interactive and OnLine (Double Conversion). Each type is designed to provide different levels of power protection and allows you to match your needs precisely with the appropriate level of power protection ..........

Therefore, the most critical component in the reliability of any UPS, but they face three fundamental challenges .......... Find out more about this topic ...... What is 'Advanced Battery Management' (ABM?)? Advanced Battery Management (ABM?) provides predictive and automatic diagnostics of UPS Battery Health and offers significant extension of battery life compared to traditional charging method plus other benefits .....

'Hot Sync' technology enables a multi-module configuration to operate in parallel without the need for inter-module communications. This eliminates the system level single-point-of-failure inherent in traditional parallel configurations and maximizes availability ..... Find out more about this topic ... How do I test my UPS to see if it is still AOK? The batteries inside your UPS have a 2 Year Warranty from the manufacturer, but a life expectancy of 3 to 4 years maximum in most instances. Sometimes batteries often need to be replaced after only 1 Year for a variety of reasons, but mainly due to the UPS being overloaded, discharged, its environmental conditions and / or lack of regular maintenance. Regular Preventative Maintenance, testing as described below and pro-active battery replacement are the best solution for reducing the risk of down time. So how do I test my UPS to see if it still working AOK ? ........... Find Out More about this topic ...... What is the 'Benefit' of having a Preventative Maintenance Service Plan for my UPS? Preventative Maintenance Service Plans and strongly recommended to maximise the reliability of a UPS ................ Find Out More about this topic ...... Why do I need 'Surge Protection' if I have an UPS? The Surge Protection circuitry in the UPS is designed to handle the 'Tail End' of a major surge, not the whole surge itself ....... Find Out More about this topic ...... What type of Surge Protection should I select? Protection Categories are broken into 5 Categories according to the specific needs of the installation. Read on to find out in which category your installation falls and what type of Surge Protection equipment you should choose ..... Find Out More about this topic ...... What is a Maintenance ByPass Switch? A Maintenance Bypass Switch is a requirement on every UPS system with equipment attached that cannot be turned off (critical load) even if the UPS system needs scheduled maintenance and / or testing. What are the advantages of installing an External Maintenance ByPass Switch? Many UPS systems come complete with an Internal Maintenance Bypass Switch allowing the UPS to be transferred to static and then maintenance bypass for servicing and repairs. However, there are important additional features which can only be obtained with the correct installation and operation of an External Maintenance Bypass Switch .....Find Out More about this topic ...... Which Generator is compatible with my UPS? You can turn to generators as a source of backup power, but they may introduce new problems, especially in facilities that use sensitive electronic equipment. That's why uninterruptible power supply (UPS) systems are popular options for that seamless transition. Still, you may experience specific problems when you operate UPS systems in conjunction with generators - problems that don't occur when you have stand-alone equipment ......

Simply put, ferroresonance is the property of a transformer design in which the transformer contains two (2) separate magnetic paths with limited coupling between them. The output contains a parallel resonant tank circuit and draws power from the primary to replace the power delivered to the load ...... Find Out More about this topic ......

Are we next for a Blackout? 2003 was the year of the blackout, giant power cuts that deprived towns and even entire countries of electricity. Although those occurring in New York and Italy were impressive, it should be pointed out that twenty or so lesser power cuts have affected around 550 million people over the last 30 years. Such figures can get you thinking. The increasingly likelihood of such power cuts occurring and their sheer scale will have increasingly serious consequences ..... Find Out More about this topic ...
