A client once purchased a line-interactive UPS system to protect their sensitive metrology units. Still, their units continued to fail from power problems. Why? Because a line-interactive system does not protect against all nine common power anomalies. Continue reading “Line Interactive vs. Double Conversion UPS – Which One’s Best?” »
At Quality Power Solutions, it’s important to us to build a knowledge base with our readers and customers, so we can create a meaningful shared dialogue on educational topics related to the critical power industry. We went through quite a few topics this year, so it’s always interesting to go back over what we shared. Here, then, is our QPS “blog year” in review summarizing our 2018 discussions.

In our connected, high-tech and high-paced world, tolerance for downtime is simply not acceptable. DC Power Plants are often used in many industries, especially telecom and network applications to ensure clean, reliable DC power is supplied to critical equipment. In our previous two articles regarding DC power plants, we discussed typical applications where they are used the most, some of the advantages they provide, and how to best maintain these systems. In this article, we’ll take a closer look at these components to better familiarize ourselves with what is going on inside this system, and their benefits.
In our last article, we discussed DC power plants, what they are, and how they are often used. Just like any back-up power system, DC power plants need regular service checks and maintenance performed to work optimally. It is important to state that DC plants, although similar to the function of UPS systems, have many functional differences and require unique training when performing annual maintenance. During a preventative maintenance visit a technician will usually isolate individual rectifiers and charging components to evaluate function and longevity. This practice helps to reduce the risk of a potential failure before it happens. Continue reading “DC Power Plant Maintenance: Keeping Businesses Running” »
Darkness took center stage at the Las Vegas Convention Center for a little over 2 hours during day two of the Consumer Electronics Show this year. Continue reading “Lessons Learned From The CES 2018 Power Outage” »
As a follow up to our Lighting inverter series, this article will focus on the components of a lighting inverter and how they may differ from a UPS. UPS systems are typically used for critical power applications where both power conditioning and uninterrupted power is required. They typically have shorter run time and rely on batteries to keep the system running in the event of an outage. While there are UPS systems that are UL924 approved, a UPS is typically used in non-lighting applications such as data centers, hospitals and other critical environments, keeping your servers, computers and other equipment operational in the event of a power outage. A lighting inverter is similar to a line-interactive UPS, where the unit passes utility power to support systems until there is an outage, then draws from batteries to provide power during the outage window.
When you think of power outages in this country, you generally think of weather related incidents and natural disasters – things like floods, fire, ice storms, heat waves and tornadoes.
It’s true, many power outages can be attributed to these events. However, believe it or not, many of the power outages that occur in the US are not the result of bad weather, but instead the result of squirrels and other small animals.
Yes, squirrels! And incidents seem to be on the rise. In fact, the number of incidents has significantly risen since we last touched on the squirrel issue in 2014. This squirrel problem is noteworthy enough that there is even a tongue-in-cheek website devoted to tracking power outages, or “cyber squirrel attacks” across the world: http://cybersquirrel1.com/ Even the Eaton Blackout Tracker lists animal related outages as causing 5% of all outages country-wide.
Critical power systems like UPS systems, generators and power conditioners are highly complex. Simple installation does not always ensure your critical loads are protected. There are at least 12 things to consider if you’re going to install your own critical system.
