Centralized vs. Decentralized UPS Systems

One of the first steps in choosing the most appropriate UPS solution is deciding whether to use a centralized or decentralized setup. While both have their advantages, knowing how to answer this question depends on a number of factors.

Here are five things to consider when deciding between a centralized and decentralized solution: [Read more…]

Protect Your Fish, Plants and Equipment with UPS Battery Backup for Aquariums

One never knows when a power outage may strike, and if you own fish and other sea creatures, you should be prepared with an uninterruptible power supply (UPS) for your aquarium. Heaters, aerators, filtration systems—all need electrical power to operate and keep fish alive. They need heat when it is cold, cold when it is hot, and oxygen to breathe at all times.

An aquarium battery backup system can prepare you for the next unexpected power outage. By purchasing a UPS system for your fish tank, you can ensure that your essential equipment will continue providing life-giving power.

Before choosing a UPS system, you’ll need to measure your total load. That is, the total number of watts put out by your life-sustaining equipment such as filters, aerators and heaters. Be sure your aquarium battery backup system can handle more watts than the total load of your equipment. Also, you may want to consider the amount of runtime you’ll need, in case the outage is longer than anticipated. Most power outages last from just a few minutes to less than an hour. If you still need help calculating the capacity (load) of your aquarium and determining the desired battery backup runtime, checkout this UPS sizing guide.

One more point to consider: pure sine wave power. Many popular brands of electric motors for aquarium filters and aerators require pure sine wave power to operate. Incorrect power output can result in motors running slowly, erratically, or not at all when the UPS is on battery. Thus, you’ll need a fish tank UPS that generates pure sine wave power, as the following choices do.

Single-Phase vs Three-Phase Power Explained

Single phase power is:

– Used in most homes and small businesses
– Able to supply ample power for most smaller customers, including homes and small, non-industrial businesses
– Adequate for running motors up to about 5 horsepower; a single phase motor draws significantly more current than the equivalent 3-phase motor, making 3-phase power a more efficient choice for industrial applications

 

 

3-phase power is:

– Common in large businesses, as well as industry and manufacturing around the globe
– Increasingly popular in power-hungry, high-density data centers
– Expensive to convert from an existing single phase installation, but 3-phase allows for smaller, less expensive wiring and lower voltages, making it safer and less expensive to run
– Highly efficient for equipment designed to run on 3-phase

 

 

To illustrate the difference between single phase and three phase, imagine a lone paddler in a canoe. He can only move himself forward while his paddle moves through the water. When he lifts the paddle out of the water to prepare for the next stroke, the power supplied to the canoe is zero.

Now picture the same canoe with three paddlers. If their strokes are synchronized so each is separated by 1/3 of a stroke cycle, the canoe receives constant and consistent propulsion across the water. More power is supplied and the canoe moves across the water more smoothly and efficiently.

7 Solutions for Powering, Protecting and Controlling Your Video Surveillance System

Security Camera, CCTV on location, airport

Video surveillance is big business. A March 2017 report published by MarketsandMarkets, an international market research firm that serves 1,700 Fortune organizations worldwide, values the video surveillance market at $30.4 billion last year and projects that number to reach $75.6 billion by 2022.

Whether you use your video surveillance system to protect your assets, monitor employee behavior, deter tampering and theft, or lower your insurance rates, you want to be sure it’s reliable. Video surveillance systems can be vulnerable to power problems, such as blackouts, brownouts, surges, and line noise, that can disrupt security cameras and corrupt data. Here are seven solutions to help your system remain functioning at its full potential 24/7. [Read more…]

What is a Public Safety DAS System?

The global public safety in-building wireless DAS market is estimated to grow from $404.2 million in 2016 to $1,740.1 million by 2021.

What Is It?
A Distributed Antenna System (DAS) is a network of antennae that communicate with a central hub to distribute signals over an area or building, such as stadiums, hospitals, campuses and airports. A DAS extends coverage across multiple antennae to provide coverage in all areas of a building, where signals could normally be degraded or dropped.  In public safety applications, the central communication hub requires uninterrupted power to ensure emergency responders can communicate over the network.
