A Business Owners’ Guide to Understanding Uninterruptible Power Supplies

Almost every business now relies on a stable flow of power in order to keep up productivity and deliver services and products. When power is lost, massive amounts of work will be lost, particularly troubling if you work with sensitive data, as well as some companies having to consider the very possible chance of injury, company damage and even loss of life. All of this can be avoided by investing in uninterruptible power supplies (UPS), giving your business the power it needs to stay on track.


So, what are uninterruptible power supplies (UPS)?

A USP allows you to completely forget about power interruptions, outages or surges. Increasingly important as the world relies on ever more data, UPS provide your systems with a stable power supply to keep everything running.

Depending on your needs, your UPS may be a small box that sits on your desk and gives you enough time to save your work and safely shut down your computer, or it may be a megawatt behemoth tasked with maintaining power to a hospital. UPSs may either have single or triple-phase configuration and can be powered by a number of different batteries or fuels.


The different purposes of UPS

Smaller UPS tend to be powered by batteries, with larger commercial models powered by fuel. Either way, UPS serve four different purposes:

  • Protecting your business from power interruptions
  • Provide enough short-term power for you to switch to your back-up supply
  • Make sure the quality of power from the UPS is dependable
  • Include additional power sources, such as generators, in case you suffer a longer-term power outage


Different types of UPS systems

  • Line-interactive UPS systems – If you need superior filtering, this is the UPS for you. The battery and inverter are permanently connected to the output. If your power fails, it instantly switches the electrical flow.
  • Stand-by UPS systems – Also known as a line-preferred UPS or an offline UPS, they contain a battery, an inverter, low-pass filter, static switch and a surge suppressor. Unless your primary power suffers a failure, the stand-by UPS system will remain on stand-by.
  • Double conversion UPS systems – If your business needs an undetectable switch in power, the double conversion UPS system is perfect. The input AC charges the back-up battery and powers the output inverter.

You can achieve consistent and reliable electricity all year round with no down-time by selecting the correct UPS for your needs.


Specialised UPS types

Depending on which industry or sector you’re in, you may need a UPS designed to perform well in a specific set of environmental factors, such as:

  • Communication centres – including server forms, you can find UPS designed to be used for this purpose.
  • High temperature – If your UPS is based in a hot environment, finding one specifically designed to withstand warmer temperatures will avoid damage to the UPS.
  • Industrial – These UPS are designed to maintain functionality in factories and plants.


How do UPS work?

Different types of Ups operate differently, but they all store power and provide it whenever you need it. When even a second’s glitch could lose hours of production, lose sensitive data and fry your systems, you’re taking a significant risk by not investing in a USP.

We would recommend that you contact the experts at Cetronic to determine what you need from your USP. Our engineers will carry out the necessary calculations to ensure all the components of your UPS are fit for purpose.


Ensure your business is safe with a suitable UPS system

If you’re looking for a proven way to ensure your systems and machinery has a stable and constant supply of power. At Cetronic, our professional team have the experience and qualifications necessary to find you a UPS system that works perfectly for your needs. UPS may seem like an expensive investment, but the knowledge that you won’t lose time, production and profit do to a momentary power surge, spike or outage is definitely worth every single penny.

Product Of The Month: Power Monitoring


Power Monitoring Surveys

Power problems? Are you concerned you may have an irregularity with your electrical supply causing machine or equipment malfunctions?

High electricity bills or looking to install some new equipment on your electricity supply? Would you like to know how much power you are consuming or how much spare capacity you have?

Are your cables warm or hot to touch? Burnt out neutrals? This may be due to high harmonic current, leading to unfavourable distortion to the voltage waveshape.

Cetronic can offer you a service to monitor the graphical power consumption (load profile), harmonic and disturbance analysis.

Product Of The Month: External Manual Bypass Switch

embsExternal Manual Bypass Switch

An external manual bypass switch enables an uninterruptible power supply system to be locally isolated for maintenance or replaced without any disruption to the load.

If the external manual bypass switch (EMBS) is supplied with or before the UPS system, it enables the electricians to complete all of the ac cabling and turn the load on. Then, when it comes to installing the UPS system, we can connect the UPS to the EMBS, and once the UPS system is turned on, we can seamlessly switch the load from the mains to UPS, without any interruption.

Product Of The Month: Constant Voltage Transformers

rsz_1constant_voltage_transformer_burnedConstant Voltage Transformer – 500iS/50Hz

Constant voltage transformers (CVT’s) use the ferro-resonant principle to provide a stable output voltage free from impulses, spikes and harmonics. They have an extremely rugged and robust design and are particularly suited to harsh environments. Requiring little or no maintenance the CVT is an ideal solution for the protection of voltage sensitive equipment in industrial applications.

Maintenance engineers want Modular UPS systems

Premium Mod HPDuring a recent site visit to provide a planned preventative maintenance (PPM), one of our engineers was drawn into a discussion about the customers existing UPS system and what features the on-site maintenance engineers would like to see in the future. They said they would like to convert to a modular UPS system, so that it is easily maintainable by themselves, and that if there ever was a problem with the UPS system, this could most probably be solved by the on-call engineer; simply swapping a faulty power module with a replacement from the on-site spares kit.
