Modular UPS: The Building Blocks of a Critical Power System

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.

Three Things To Know About UPS Scalability

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.

UPS Battery Monitoring Basics

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.

Wet cell UPS batteries

Getting to Know Your UPS Batteries II- Wet Cell Batteries

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.  Continue reading “Getting to Know Your UPS Batteries II- Wet Cell Batteries” »

VRLA (Valve regulated Lead Acid) UPS batteries

Getting to Know Your UPS Batteries: VRLA

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: Continue reading “Getting to Know Your UPS Batteries: VRLA” »

Types of UPS Batteries: The Heart of Your UPS System

Your UPS system is one of the most crucial components in your critical power infrastructure, and for your UPS, the batteries  are really the “heart” of that system. Even though your UPS needs that heart, batteries are often neglected.  In the next few weeks we’ll go into more detail about each type of battery that can be used in a UPS system and the advantages and disadvantages for each type. It should be noted though, that regardless of the batteries you choose, all batteries decrease in their ability to store and deliver power over time. However, if you follow all guidelines for storage, maintenance and usage, eventually you will still have to replace UPS batteries on a schedule to get the best usage out of your UPS.

UPS Maintenance- What to Watch Out For

We previously discussed what you should look for when reviewing a proper service contract for emergency back-up power systems maintenance. When you hire a qualified firm to perform maintenance inspections on your equipment, you need to have total confidence in that firm’s level of knowledge and level of execution of inspection and testing. But how do you know what is most important to look for when that firm shows up at your office, ready to perform maintenance? We will briefly discuss what you should be looking for, and also what to watch out for with these inspections. Please be aware that this is an abbreviated list and should not be considered comprehensive.
