UPS and Power Back-UP Solutions

UPS and Power-backup Solutions

Commonly known as a battery backup, an uninterruptible power supply (UPS) is a rechargeable battery used to backup main power feeds. It also provides seamless power when there is a mainline utility outage.

This seamelessness distinguishes the UPS from standby generators. Generators come online within seconds of a power outage but create a break in the power current as their fuel engines turn on. The UPS positions between backup generators and critical equipment to ensure continuous power until those longer-lasting power sources can engage.

Digital Online UPS unit is more than just batteries as it also offers power conditioning for added protection against problems (surges and voltage spikes). They use active filters to remove harmonic distortions for a clean, consistent AC waveform.

The average consumer may be familiar with small UPS devices for the home and office space. These provide sufficient power for a controlled shutdown needed to protect against equipment damage or data loss. These small units may even provide line conditioning and surge protection. There are not intended to supply power for long durations — sometimes only minutes at a time.

However, enterprise or data center UPS units found in healthcare, transportation control, monitoring, or financial services facilities provide top-class power protection for heavy loads.

Digital Online UPS Use Cases

Applications of the Digital Online UPS device range based on the unit’s design and quality. They fit a variety of cases from everyday to extreme. Some normal operating conditions demand high-quality power for sensitive electrical loads in industrial applications or even rugged situations. Some typical circumstances include:

General everyday power backups for offices and home systems, which are simple and market-friendly.

Industrial and process-sensitive applications that require a UPS to provide high-capacity, three-phase, seamless power.

Medical centers and emergency facilities that need UPS units to provide clean and reliable power for critical life-saving equipment

Data centers and vital telecommunications facilities that need a backup for high-load and highly sensitive electronics

Military-grade and rugged applications that require protection from humidity, altitude, shocks, vibrations, and sand and dust.

The Three Main Types of UPS Devices

UPS devices fulfill many use cases, but their topology or type comes in three basic configurations.

Single-conversion UPS devices are the simplest UPS topology. AC power input is directly sent through the UPS to the output loads. At the same time, AC power is also channeled through an inverter to recharge its batteries. If the main power supply drops out of pre-defined limits, then the main power flow switches to batteries until the main power returns to normal.

There are two popular single-conversion UPS designs. Standby UPS units act as described above, feeding utility power until a problem detects and then switching over to batteries. Line-interactive UPS units act like standby UPS. It has the addition of a power regulator that conditions input voltage to normal levels before passing through to sensitive equipment. In line-interactive units, if power should drop out of predefined regulated limits, batteries take over.

Double-conversion UPS devices create an added layer of protection for output devices. AC power feds into the UPS immediately converted to DC power, and then reconverted back into AC power — a double-conversion. This double conversion isolates loads from the raw utility power entirely, outputting only clean and reliable electricity for critical equipment. If the main power should fail or drop below the UPS limit, batteries take over.

Multi-mode UPS devices offer features that define single- and double-conversion UPS devices. Under normal operations, multi-mode UPS units act as line-interactive systems, regulating AC power input within safe tolerances and supplying directly to loads. This method is the most efficient. If power should drop out of this tolerance, the UPS switches to a double-conversion power method, converting AC power twice.

Backup batteries

A backup battery provides power to a system when the primary source of power is unavailable. Digital Online Backup batteries range from small single cells to retain clock time and date in computers, to large battery room facilities. Small backup batteries may be primary cells; the prime power supply keeps rechargeable backup batteries charged.

Most of our UPS batteries have an expected life of 3-5 years. Some Factors shorten the life of the battery, such as temperature, humidity, and frequency of power events.

UPS Battery Life

The useful service life of UPS batteries is an important consideration and varies based on many factors starting with the battery chemistry. Valve-regulated lead-acid batteries (VRLA), for example, typically last 3-10 years while lithium-ion may last 8-15. Although they have a specific life expectancy, actual battery service life differs from designed battery life because of four factors:

Ambient temperature plays a significant factor in shortened battery life. A typical range is 55-77 degrees Fahrenheit (15-25 C). Some studies indicate that operating a UPS in hotter ambient temperatures reduces battery life. Sometimes a 15 F increase can reduce battery service life by 50%.

Battery chemistry is such that its ability to store and deliver power diminishes over time, despite following all the usage guidelines.

Discharge cycling occurs when the UPS switches from main power to battery power. Every time this cycling happens, the relative battery capacity reduces by a fraction of a percent of the total capacity. For example, lead-acid chemistry has a maximum number of discharge/recharge cycles before the chemistry depletes.

Maintenance plays another significant but actionable factor in battery life. Although often marketed as maintenance-free, UPS devices do require periodic maintenance to ensure maximum service life. Maintenance-free refers to the fact that the batteries do not require fluid.

Types of power disruptions our UPSs protect against

Our UPSs protect against downtime caused by various kinds of power disruptions, including:

Power surges: Surges are short bursts of power that can result from several external and internal sources:

  • External: Utility maintenance work, lightning strikes, and power line disruptions, such as from snowstorms, downed tree limbs, and transformer problems.
  • Internal: Routine on/off cycling of motors in machinery, air conditioning and refrigeration units, and more, as well as faulty wiring.

Brownouts: which are reductions in the flow of utility power during high-demand periods

Unplanned power outages can result from issues including:

  • Lightning
  • Natural Disasters: hurricanes, snowstorms, high-speed winds, and other weather conditions
  • Utility and construction work
  • Motor Vehicle Accidents

Planned power outages:

  • Utility maintenance and system upgrades
  • Planned outages are now occurring in areas such as California, to protect against wildfires caused by sparks coming from utility equipment.

Buying the right UPS with us: Key considerations

Assessing which UPS battery backup is best for your business requires going through a series of questions regarding what equipment you need to protect. You should also consider the ramifications of downtime with that equipment, whether a generator is available as a backup power source, and more.

  1. Determine the size of the load that needs UPS protection, and, hence, the capacity of the UPS

Assess which devices warrant UPS battery backup protection and the power required by each device so that you can calculate the required UPS capacity. The power consumption of IT servers, computers and workstations, and networking equipment are obvious places to start. Still, you might also want to include devices that are critical to the day-to-day operation of the business. Assess what applications each component supports and how the loss of that application will affect your organization.

For each device connecting to the UPS, determine the power consumption (watts) of that device.  Power consumption is from the equipment nameplate or manufacturer documentation.

The required UPS capacity is the sum of the power consumption of the devices connecting to the UPS.

  1. Assess the required UPS runtime for critical devices and applications

Step 2 is to determine the desired UPS runtime for continued operation in case of a power failure.

If you have a generator, the required runtime of the UPS may only be few minutes to safely start up and transition to the generator.

On the other hand, your goal may be to have enough runtime to safely shut down servers and workstations to avoid data loss or corruption.

For applications like networks and Internet access, you need 1 to 2 hours of runtime to be able to ride through most outages.

Keep in mind that, in general, the more equipment you connect to a single UPS, the shorter its overall runtime will be.  An alternative may be to use separate UPS for certain applications.

  1. Determine the number of outlets required

Add up the number of devices that you need the UPS to support. Also make sure the UPS has enough outlets to meet your immediate needs, and also leave some room for growth.

Alternatively, you can use a power distribution unit (PDU) to provide additional outlets, but be careful not to overload the UPS.

Some UPS models also include outlets that only support surge protection.  These outlets do not provide battery backup. Make sure you understand the features of the UPS you are buying and that it has enough battery backup outlets to meet your needs.

  1. Consider UPS installation requirements

UPSs come in a variety of sizes and form factors. Tower models are standalone units that sit on the floor, or on a desk or shelf. They often backup desktop computers, servers, and routers in an office environment.

Rack-mount UPS models are typically designed to fit in a standard 19-inch IT rack along with other IT equipment.  Rack-mount UPSs vary in size, and their height measures how many vertical slots it occupies in the rack. Each space known as a “U” and measures 1.75 inches.

UPSs designed to use lithium-ion batteries tend to be smaller and lighter than similar models that use traditional lead-acid batteries. These enable you to fit more backup power capacity in the same space – or the same capacity in a smaller space.

UPS Advanced Features

UPSs can differ considerably in the exact set of features they support. The following are additional common features found in modern UPSs that you may want to consider.

Remote Monitoring and Management

UPSs with built-in network ports or support for network management cards (NMCs) monitored and managed remotely. This is especially important for UPSs installed in branch offices or edge locations with limited or no IT staff on site.  In this case, a centralized IT or facilities group can monitor the status of all UPSs and notified of issues. NMCs may also support environmental sensors, enabling the remote monitoring of conditions such as temperature and humidity.

Remote UPS Outlet Control

Some UPS models include outlets or outlet groups managed remotely. It also includes the ability to monitor energy usage, and cycle power or turn off these outlets or outlet groups. This can enable someone in a remote operation center to reboot a hung server or network switch, for example.

LCD Control Panel

From a local perspective, an LCD screen on the UPS can display useful information such as battery health and power conditions. It also facilitates local management and control of UPS.

User Replaceable Batteries

No battery lasts forever, and UPS batteries are no exception. But given that the main purpose of a UPS is to ensure uptime, UPS battery replacement must be a quick and easy process.  Consider models that feature a removable panel that makes it easy for the user to replace the batteries.

Lithium-ion Batteries

Lithium-ion batteries are becoming more common in UPSs and for a good reason. They can easily last twice as long as traditional lead-acid batteries yet weigh far less and take up less space. They also support faster charging and more charge/discharge cycles. In many cases, the lower total cost of ownership of a UPS with lithium-ion batteries will make them well worth the additional up-front cost.

Extended Runtime

Some UPS models support external battery packs that can provide extended runtime beyond what a UPS’s internal battery offers. These enable users to get potentially hours of battery backup time for critical loads.

ECO-mode for Energy Savings

UPS Eco-mode seeks to save energy. It bypasses the voltage regulation and energy conversion processes of the UPS if it determines that the utility input power is of good quality.
