Commercial UPS

Is a commercial UPS right for me?

Commercial UPS systems are commonly found in IT applications, such as data centres, network hubs and computer rooms. Commercial UPS systems are generally less durable than industrial UPS systems but are much lighter, easier to install and maintain, and are more affordable than industrial UPS power supply systems.

One of the most important considerations to make when choosing a UPS is the physical conditions it will withstand. The average commercial UPS should be kept in an ambient temperature range of 20-25 degrees Celsius and with an air humidity of 10-55% for optimum performance. In technological and IT applications, such as data centres, these conditions are kept consistently, not just for optimum UPS performance but for optimum performance of servers and other vital hardware. This makes commercial UPS power supply system’s perfect for use in these kinds of environments.

Our commercial UPS range

With a commercial UPS range from 1kVA to 1MVA, Dale's uninterruptible power supplies comprise both Modular and Monolithic architecture allowing a tailored configuration to suit your needs. Many have parallel capability allowing you to further increase the resilience of your power infrastructure by adopting N+1 redundancy.

Our uninterruptible power supplies are compatible with a wide range of accessories such as External Maintenance Bypass Switches, Communication adapters (Modbus, SNMP, Volt Free Contacts et al), additional battery packs, parallel kits, Increased battery chargers and are suitably designed to be used with our range of Dale generator systems.

You can buy a replacement UPS battery from Dale, and we have a great range from which to choose. Our batteries include: valve regulated lead acid batteries; flooded lead acid batteries; flooded nickel cadmium batteries (NiCd batteries); gas recombination low maintenance NiCd batteries; lithium ion stationary batteries. Unsure which UPS battery you need? We’re more than happy to advise and guide you on the right battery replacement for your UPS system.

Yes we can. Beyond environment based UPS, Dale offers a range of alternatives including containerised UPS systems with a robust solution to match your need.

Put simply, yes. A generator service and/or UPS service can determine any existing and future power supply problems that could impact equipment performance. Planned and preventative maintenance can extend machine efficiency, assures optimal working conditions and conserves the life span of the equipment. Along with determining when replacements will be needed for a seamless transition, planned and preventative maintenance is a far cheaper solution compared to complete equipment replacement.

Generators are not a source for uninterruptible power therefore a UPS (uninterruptible power supply) bridges the gap between the two. As a critical power provider we can help you decide what is the best solution for your needs.

When disruption to your power occurs it will provide instantaneous protection by immediately resorting to the onboard battery which forms part of the uninterruptible power supply.

Nearly all electronic and electrical equipment, regardless of how well-designed and built it is, will eventually break down unless it is maintained according to the manufacturer’s instructions. Wear and tear is common with electrical equipment, but it has severe consequences for UPS systems and generators, where financial, reputation and potentially life-threatening damage comes into play. It is highly recommended that as a minimum you service your power systems annually in order to maintain its working lifecycle. Our service contracts include everything from AC maintenance, DC maintenance and generator maintenance through to analogue metering, intelligent monitoring, remote monitoring and spare parts, as well as callouts, minor fault fixes and access to our customer portal, where you can access management information reports and other key details on your power supply systems.

UPS manufacturers usually recommend that UPS maintenance should be carried out within the first year of installation, and then annually from there on out as a minimum. However, if you notice any issues with your UPS system beforehand, then you should always contact your power supply partner as soon as possible to rectify them, and to ensure that UPS repairs are carried out swiftly and efficiently. The right check up could be the difference between business continuity and costly downtime, so UPS maintenance is always worth the time and effort.

Batteries have a typical lifespan of 3 – 5 years, with causes of battery failure including loss of electrolyte and inaccurate float charge voltage. However, factors such as battery chemistry, battery cycling and suitable storage conditions can greatly affect how long your battery lasts. We strongly recommend carrying out battery maintenance tests to keep abreast of any battery faults or issues, as batteries are one of the most integral parts of your UPS system. Battery testers can visit your business, site or facility every 6 months to a year, ensuring you’re always in control of your critical power equipment.

As batteries go unused, with no charging schedule, their battery life will decrease. When it comes to the self-discharge characteristics of lead-acid batteries for example, it is important that they are charged after 6-10 months of battery storage. Otherwise, permanent loss of capacity will occur between 18-30 months.

Generator: Provides stand by power until the mains power can be reinstalled.

UPS (Uninterruptible Power Supply): Ensures a seamless transition from mains power to the standby power (generator).

Batteries: Provide the power to your UPS and Generator.

Upon installation, the UPS requires further attention before it is fully operational. Certain connections, components and peripherals need to be checked and tested to ensure that the UPS works as designed. Once these checks have been completed, the UPS can then be commissioned and will operate at optimum performance without the need for more tests.

UPS maintenance is extensive and far-reaching, and when carried out by our technical team, is highly successful. UPS maintenance involves the testing and inspection of your UPS systems, and making any necessary adjustments for power continuity. A visual inspection of the area surrounding your UPS and battery equipment will typically be carried out first, with UPS maintenance seeking to identify any operational abnormalities. Following this, we can carry out battery maintenance, battery management, enclosure maintenance and load bank testing, as well as control system management, voltage testing, and replace faulty parts with new ones. This can include batteries, capacitors, alternators and fans.

An uninterruptible power supply (UPS) provides a source of power for the equipment it protects. If there is a disruption to power, the UPS has an on-board battery to automatically supply to electrical equipment until the disruption is over or back-up generators kick-in.

WIMES (Water Industry Mechanical and Electrical Specifications) UPS (uninterruptible power supply) is a robust critical power system built for harsh atmospheres that could affect electrical equipment. As a critical power provider we can help you decide what is the best solution for your needs.
