Single Phase UPS Systems

The technology used to generate and distribute electricity in many countries around the world produces either a three phase or single phase supply.

As it moves closer to the point of use, local substations reduce the electricity voltage and add a neutral and earth reference. The substation supplies a single phase, 230V supply (made up of a single phase and neutral) to energy consumers (businesses or consumer customers) in its vicinity, or a three phase supply to larger energy consumers.

The supply coming into an industrial estate, factory, office block or other large building will be a three phase, 400V 50Hz supply. It is then converted to a single phase supply by the distribution network within the building so that wall sockets will have a voltage of 230V at 50Hz. This provides a maximum current typically: 10, 13, 16, or 20 Amps.

UPS are designed to work on either a single or three phase supply, but not both. The difference between them is really to do with how they handle the electricity supply, their switching mechanisms and size of output they are designed to enable.

At Critical Power Projects, we supply a number of desktop, floor standing or rack mounted, single phase UPS and single phase UPS systems up to 3kVA from leading manufacturers across the globe. We employ a team of qualified and experienced UPS experts, fully conversant with the full gamut of requirements of power protection by all sectors of business and industry. We also understand which single phase UPS will be best for your requirements, and as we are manufacturer independent, we are free to supply a solution that best meet your needs. If it’s just the product you want, we can ship it to you quickly (from stock or on special order). For additional power security, some single phase UPS (and those rated above 3kVA) can be hard wired, in which case we can provide expert installation and project management.

We also provide battery extension packs to increase battery run time, plus bypasses, remote monitoring, power management and power monitoring solutions.

For advice on UPS, or if you would like to know more about single phase UPS and the range of power protection products and services we supply, or if you would like us to arrange a site survey, or quotation, please call: 0800 978 8988, fill in our contacts form, or send us an email with your details and we’ll call you.
