Avoid Power Outages With an Uninterruptible Power Supply System

Unexpected power outages cost American businesses around $150 billion yearly and put them at risk of losing productivity and profitability. Businesses can strengthen their operations with an uninterruptible power supply (UPS). These electronic devices operate as backup power sources to keep your most important operations running smoothly. Integrating these tools into your contingency plan will give you the confidence you deserve.

COMMON REASONS FOR POWER LOSS

Power outages occur for many different reasons, including:

• Storms
• Animals
• High demand
• Car accidents
• Earthquake
• Lightning

Power outages put business operations at risk and can cause costly project delays. UPS systems allow your workflow to continue as usual during an outage, powering your heat, equipment and other necessities to remain productive and profitable. During long-term blackouts, you can count on these systems to give you enough time to convert to an alternate power source.

WHAT IS AN UNINTERRUPTIBLE POWER SUPPLY SYSTEM?

UPS systems provide critical backup power to keep essential equipment operating and decrease the risk of downtime. Unlike traditional power sources such as generators, these machines switch on seamlessly and eliminate any effect of equipment interruption. These tools are available in various models and can take unique shapes, such as a desktop system for securing your personal computer or a facility-wide power source relying on mega-ton or megawatt configurations.

You will typically find battery-based systems in smaller operations like the home computer or office and the flywheel configuration in bigger systems that power large facilities. The bigger systems provide reliable electricity within seconds by combining switchgear and power transformers. Each UPS configuration is a filter to protect against outages and other anomalies, providing critical operations with clean, stable and consistent power.

HOW DO UNINTERRUPTIBLE POWER SUPPLY SYSTEMS WORK?

The different types work differently, but they all aim to store and supply power when needed. In a data-driven world, even a momentary glitch with the power has the capacity to result in lost data, zapped systems, missed changes, corrupt files and lost production.

A flywheel or battery-powered UPS plugs into a power source, draws energy and stores it. Many times, it filters and refines the energy as well. The three main uninterruptible power supply systems are standby, interactive line and online.

• Standby UPS System: Standby UPS systems are offline devices that quickly switch to battery power following an unexpected power outage to deliver a steady supply of short-term electricity.
• Line-Interactive UPS System: This UPS type provides superior filtering capabilities with a battery and inverter that are always connected to the output, and if power fails, a switch changes the electrical flow.
• Double Conversion UPS System: Double conversion UPS system configurations receive incoming alternating current (AC) power and convert it to direct current (DC) before converting back to AC to eliminate noise, spikes or surges.

Uses of UPS Devices

Keeping a steady stream of clean power is important anywhere you have operations that can’t stop. Using a UPS can protect data and maintain high efficiency — abilities required throughout various applications, including hospitals, data centers, universities and other facilities. Uses and applications for UPS systems include:

1. Data: A UPS for applications like a server farm or communication center.
2. Temperature: Some people need a UPS that will withstand hotter climates.
3. Industrial UPS System: These power systems are geared toward use in such settings as manufacturing and other types of plants and factories.
4. Medical: Hospitals and other medical settings use a UPS to ensure continuous operation of critical equipment like life support.
5. Military: These systems are certified for quality under military specifications.

Costs Associated With Your UPS System

UPS devices are often built in various configurations to meet specific facility demands. They commonly come in single- or triple-phase designs, powered by either a set of batteries or by a flywheel component. These variations can alter your required investment, totaling tens of thousands of dollars.

However, an efficient, Energy Star-rated UPS system can help reduce general energy loss by as much as 55%. For example, a 1,000-kVA UPS used in a data center application could save as much as $18,000 per year in energy costs.

It is usually necessary to pay an electrician for anything more than the basic installation of the smallest system. Hobbyists and the inexperienced should know that attaching a UPS and its accouterments is a job for the professionals. Most UPS systems need a cool, dry, dust-free place to exist, and if you choose a battery-based system, know that the batteries last about 5–10 years and must be disposed of properly according to environmentally friendly standards.

ADVANTAGES OF USING AN UNINTERRUPTIBLE POWER SUPPLY SYSTEM

UPS systems provide exceptional reliability and protection and keep critical systems running. They refine the power quality as it reaches your building, office and equipment, providing unrivaled protection against short- and long-term power outages. Experience benefits of UPS such as:

• Continuity: Experience no outages to critical equipment like computers or factory production lines.
• Consistency: A UPS’s electronics enable quick activation and signify when alternate power is needed to eliminate errors or faults and streamline the process.
• Protection: These systems create an extra layer of protection against electrical surges, spikes, dips and even total failure, as they can detect potential threats and take the necessary precautions to avoid damage.
• Filter: A UPS, such as a line-interactive UPS, refines incoming power and adjusts outputs to ensure internal components have unrivaled access to safe electricity.

 

FLYWHEEL UPS SYSTEMS ARE LEANER AND CLEANER

A Caterpillar® UPS with flywheel technology, available through Warren CAT, provides the most superior power and advanced technology in UPS systems. They feature an exclusive kinetic-energy storage device that functions like a traditional UPS but without batteries and with much less maintenance and hassles.

Cat UPS systems’ complete line offers capabilities ranging from 150 kVA to 3.6 MVA and are designed to carry a facility through an outage or interruption. Depending on the model and technology, they will refine the incoming power so it’s as clean as your system needs. Flywheel-style Cat UPS systems have several advantages, like no-break technology and an infinite life cycle.

THE COMPONENTS OF A FLYWHEEL UPS SYSTEM

1. Input contactor
2. Static switch
3. Line conductor
4. Inverter fuse
5. Filter inductor
6. Utility converter
7. Flywheel converter
8. Flywheel system
9. Bypass and output contactors

Options include cabinets with static bypass, MMU isolation, MMU connection, maintenance bypass and dual output. The flywheel motor compartment contains no permanent magnets and has a magnetic bearing integrated into the field circuit.

ADVANTAGES OF A FLYWHEEL UPS SYSTEM

• Produces superior-quality output
• Eliminates batteries or reduces the number
• Lowers system maintenance, operating and replacement costs
• Requires less upkeep
• Needs less space at a size that’s about 75% smaller than battery-based systems

A flywheel UPS addresses both efficiency and environmental considerations. For example, a traditional battery-based UPS of 300 kVA would occupy 40 square feet, weigh about 13,000 pounds, and use about 52,269 BTUs. A Cat UPS 300 kVA system would occupy 14 square feet, weigh 4,475 pounds and use about 25,300 BTUs.

One of the Cat UPS systems is a high-endurance model designed to operate at temperatures as low as -4 degrees Fahrenheit and as hot as 104 degrees F. You can put monitoring equipment for the Cat UPS system anywhere in the building, with optional Ethernet connections and various choices for computer display.

Caterpillar ingenuity masters the science of using kinetic energy to provide a true, uninterrupted power supply. When power surges, dips, or ceases, inertia keeps the rotor spinning, creating kinetic energy to convert to electricity. The flywheel spins with such low resistance (virtually none), so frictional loss remains very low, creating a super-efficient environment.
