The CRITICALPwRCalc is designed to help end users, contractors and electrical engineers get a clear perspective of projected and anticipated energy usage, plus an accurate calculation of load sizes and characteristics before purchasing strategic equipment - such as UPS (uninterruptible power supplies), generators and PDUs (power distribution units).

With CRITICALPwRCalc, users can easily add Critical Power Supplies to their Contacts list by tapping the “yes” key, plus they can call the company, book a free site survey, “Tell a friend” and access the power calculator and cost calculator using simple ‘one-tap’ technology.

• Kilowatts (kW) to Kilovolt Amps (kVA)
• kVA into kW
• kW into Horse Power (HP)
• HP into kVA 
• kW into BTU
• Amperes
• UPS Power
• Generator Calculator

There is a useful Amperes calculator included, which is important as nameplates of equipment from different manufacturers often display ratings differently, some in Amps, some in Watts and the calculator makes it easy to achieve an accurate picture of real power alongside apparent power and the power factor (the ratio of real power to apparent power). Understanding power factor is important for efficiency. If the ratio between the two is great, then power factor correction can be applied to the installation. The closer to unity power factor is, the more efficiently the system will run. A UPS power calculator also enables accurate calculation of UPS load sizes. 

It is important for users to know and understand the differences between kW and kVA in power protection scenarios and be able to convert from one to the other. UPS ratings are generally presented in kVA while generator ratings are usually in kW. Some manufacturers stray from the norm, which can cause confusion. CRITICALPwRCalc provides a quick and easy-to-use aid to accurate power calculations.

Diversified Industrial Manufacturer Eaton has announced that its Power Quality business has launched the Eaton 9PX Uninterruptible Power Supply (UPS), which will shortly be available from Critical Power Supplies.

If you would like the latest information on the new Eaton 9PX please call Mark on 0800 978 8988 or email Sales@criticalpowersupplies.co.uk.

The next generation of energy efficient 5 to 11 kVA future-poof UPSs for virtualised environments. For IT and facilities managers who are targeted with managing rising energy costs and consumption, the 9PX offers the ideal power protection solution due to its unmatched power density and highly effective power use.

The units feature up to 95% efficiency in online double conversion mode, and 98% in high-efficiency mode, with a power factor of 0.9, enabling them to deliver 28% more power than other UPSs in the same class. As a result, the 9PX is particularly suitable for users looking to protect their equipment in computer rooms and small data centres as well as in industrial, manufacturing and medical applications.

The devices come as a compact rack or tower delivering up to 5,400 W in a 3U form factor and 10 kW in 6U. To allow for enhanced manageability, a sophisticated graphical LCD display provides clear information on the UPS’s full status and analytics as well as configuration capabilities. The multilingual screen also tilts 45° for ease of viewing and its position can be adjusted to suit rack or tower use. In double conversion topology the 9PX constantly monitors power conditions and regulates voltage and frequency for optimised capacity management.

Users have the option to monitor energy consumption via the LCD or through Eaton’s Intelligent Power Software Suite, which is compatible with all major operating systems and virtualisation software. Thus, the 9PX easily integrates with virtualised IT environments such as VMware vCenter, Microsoft HyperV, Citrix XEN and Red Hat KVM. Connectivity options are broad and include USB, Serial and Relay as well as a slot for an optional network card.

To ensure service continuity, in the unlikely event of issues with internal electronics for example, Eaton has equipped the 9PX with redundant components as well as with an internal self-powered bypass. On HotSwap models, a maintenance bypass is also available for easy replacement of the UPS without powering down critical systems. The devices allow for parallel operation so that users can either build a redundant solution or scale up their UPS system using HotSync technology to double the power at a later point in time depending on their infrastructure growth.

The 5 and 6 kVA models feature load segment control, which enables prioritised shutdowns of non-essential equipment to maximise battery runtime for critical devices. Eaton’s Advanced Battery Management (ABM) technology includes a three-stage intelligent charging process that optimises recharge time, eliminates overcharging and continuously monitors battery condition. Thanks to ABM battery service life can be extended by up to 50%. Furthermore, users can increase runtime by adding up to 12 external hot-swappable battery modules. As a result, the system can provide power for several hours if necessary. All Eaton 9PX UPS units come with a two-year warranty covering the entire unit including batteries.

“Sustainability is at the core of Eaton’s business and values. We are proud that with the Eaton 9PX UPS we can offer the market one of the most sophisticated systems in its class, and one that enables customers to save up to 40% in energy usage compared to other equivalent products available today,” said Christophe Jammes, Product Manager at Eaton’s Power Quality business. “At the same time, we are able to provide users with a future-proof solution thanks to the parallel operation capability and unmatched readiness for integration into virtualised environments.”

“Remote monitoring is expensive, unnecessary and I don’t see the value.”

 Is this your view?

Well, if it is we’d hazard a guess you’re not alone. Historically, monitoring power solutions has been cumbersome, time consuming, manpower-hungry and expensive.

 Today’s monitoring systems are based on state-of-the-art technology that enables power protection equipment (UPS, generators, batteries, PDUs and the environment) to be monitored remotely, 24/7 – without being time consuming and costly. 

Today’s remote monitoring systems offer real, tangible value.

“Why do I need remote monitoring?”

Without remote monitoring, who’s going to watch over your system? You?

Unless it’s part of your job, it’s unlikly you’ll have the time. And what about resources? Do you have qualified engineers on hand, spare parts in stock?

And what if (as is common at many sites) you operate in a multi-vendor environment? Do you have the necessary time to call and liaise with numerous third-party suppliers to get the job done?

 Your power protection system is central to the business continuity of your facility. You can’t afford to take any chances. Remote monitoring covers you if something goes wrong.

 Potential problems can be avoided before they turn into emergencies and breakdowns can be fixed or replaced fast.

Remote monitoring adds value to your business and pays for itself over time. It helps to keep equipment in peak condition and increases system availability and uptime. This is especially true when remote UPS monitoring is part of a maintenance package.

 “What remote monitoring packages do you offer?”

 We offer a number of bespoke and off-the-shelf remote monitoring packages. We can supply them as standalone products, as part of an extended warranty or bundled in with a maintenance contract tailored to suit you needs. We are a third-party UPS maintainer, which means we work with the leading brand service engineers who are the best in the business and we have access to them – nationwide.

Our remote monitoring systems enable us to observe and control your critical power solutions, round-the-clock, from our Critical Watch facility. We can immediately detect and quickly respond to alarms and alerts, interrogate the system, issue command instructions and ensure engineer visits are enlisted when absolutely necessary.

We offer three levels of service:

CPS8500 Critical Watch – the highest level of service we offer in which we monitor your power systems, 24/7. We deal with alerts straight away and respond to alarms by interrogating the systems to find out what’s wrong, performing remedial tasks where possible, send messages to whoever needs to be informed or despatch an engineer to site if necessary.

e-Monitoring – is the next level down. We monitor your systems 24/7, send messages whenever we receive an alert or alarm signal and send a full status report at the end of each month.

SMS diallers – is an entry-level monitoring service. Your systems are monitored 24/7 and alerts, alarms and anomalies are responded to by us sending SMS messages to as many as five designated people.

All our remote monitoring services are simple to set up, fast, reliable and do not entail purchasing custom software. They are supported through our own 24/7, customer support helpdesk.

“What about response times?”

As part of a maintenance package, we can guarantee response times of within four, eight or twelve clock hours (working hours). Alerts from remote monitoring packages are received by our Critical Watch facility almost instantly and responded to straight away.

“How much does it cost?”

Cost depends upon each customer’s specific requirements in terms of the level of support they need and the criticality of their power protection system but what we normally do is work out a fixed, monthly cost agreed with each customer (based on meeting their needs). For details of what this can include, click here:

“What if I’ve got lots of equipment from different manufacturers?”

It doesn’t matter. We work with the leading brands and our team of engineers are all qualified to the highest standards, skilled, experienced and accredited by those leading brands – we can go in almost anywhere. And we are accredited to work in sensitive environments like telecoms sites and pharmaceutical companies.

“What about spares, how long will it take to get them?”

Our team of engineers carry many of the most commonly required parts and spares. This is what they do everyday. If, for some reason, they don’t have what’s needed, chances are we will stock it in our large warehouse facility in Thame in Oxfordshire and we can despatch it for next-day delivery. Failing that, we have preferential relationships with most of the leading brands, and this enables us to get hold of stock and supplies very quickly.

 “Hmm, sounds good. I’d like to know more.”
