Organizations rely more heavily on reliable power systems than ever before. Selecting and installing a UPS system is a project that can be costly, but also carries significant risks if improperly installed. In order to avoid those risks, we have provided the three must-do steps to installing a UPS system properly. Read more
For years, data centers have used multiple high capacity UPS systems to obtain “N+1” redundancy and ensure high availability of power for their critical systems. More recently, the trend has been to use smaller modular systems that can scale with load demand. In fact, modular UPS systems are one of the fastest growing product in the 3 phase UPS industry, expecting to reach an estimated $2.5B in sales by 2020.
Using a modular UPS design can also allow for different types of scalability that you may not get from a more conventional UPS. We will explore how this set-up typically works, advantages and key considerations for a modular UPS, and show examples of some of the more common modular UPS systems in the market today. Read more
Scalability is a word that often gets highlighted in conversations about growth and expansion. But what does scalability actually mean when talking about UPS systems? As organizations grow, merge or gain efficiencies, UPS scalability becomes a critical discussion point. There are several ways scalability can apply to a UPS. It can apply to scalability within a single unit or multiple systems. For this discussion, we will examine both why scaling your UPS system may become necessary for certain businesses, and the three main ways to scale a UPS. Read more
As much as 65% of all UPS back-up system power failures are battery related. That’s a staggering number, but is easier to understand when you consider all the potential issues that can affect UPS batteries. Power anomalies, overheating, improper charging or low electrolyte levels for certain types of batteries can all cause serious issues for the UPS.
The second battery on our “get to know you” list is the Wet Cell, or Flooded Cell battery. UPS Systems are used in a variety of applications and, as a result, may require a wide variety of run time requirements or discharge characteristics. The battery cell is comprised of a hard plastic enclosure, typically Polycarbonate or Styrene Acrylonitrile (SAN) Plastic, lead plates and an electrolyte that allows the flow of current. Read more
Now that we have a better idea of our UPS battery options from our previous article, we can take a look at these options individually in more depth. We will start with the most popular option currently, the VRLA UPS battery.
VRLA, or Valve Regulated Lead Acid UPS batteries, are also sometimes called “maintenance free” batteries. This term is a misnomer, as VRLA batteries still require cleaning and regular functional testing. The term “maintenance free” comes from the fact that you are not able to add fluid to the battery. The term “valve regulated “means these batteries limit the inflow and outflow of gas to the cell.
In a standard UPS configuration, VRLA batteries are typically set up in internal or external strings that can range from 1 to 40 batteries, depending on the application they are being used for. You may also see either single or multiple strings running in parallel to each other.
VRLA batteries are the most popular UPS battery type currently. Why the popularity? There are four easy reasons: Read more
By now we have examined flywheel UPS machines from several different angles: their history, how they work, and how to properly maintain them. We also need to examine the most obvious question: What considerations go into making sure a flywheel UPS actually makes sense for your business? Today we will examine some things to consider when looking to purchase a UPS system. Read more
In our previous articles, we discussed an overview of Flywheel UPS systems and the types of flywheel technology on the market today. Now that we know a little more about Flywheel UPS in general, we can talk about how to best maintain them for optimum performance. We always recommend reviewing any published OEM requirement for your flywheel system to ensure that your equipment is operating at peak efficiency and reliability. Read more
In the world of emergency power, your equipment is only as good as its ability to stay on when the lights go out. Most backup power comes in the form of generators or batteries and within these categories, the choices can be overwhelming in terms of size, load capacity, generator or UPS life, repair costs, etc. To make things easier, it helps to better understand what the main types of emergency power systems look like, how they operate, and what functions and applications they best serve before deciding what you need. Today we will look more closely at one of these emergency systems types, the Flywheel UPS. Let’s start with the basics.
