We can give you unbiased advice on what is the ‘best of breed’ for all requirements - irrespective of manufacturer.

We can offer you a UPS range from as small as 300VA (for a small desktop PC) to several MVA (for the largest of Data Centers or very large loads). There are different technologies available to give various levels of power conditioning; again we can give you advice on what is best for you.

If long power outages are a threat to your operation we can offer diesel generators to provide continuous back up for the UPS, air-conditioning and other essential loads such as lifts, lighting etc.

We can supply stand-alone UPS or generators. However, should you require a turnkey complete standby power package we can offer a complete service from site survey, detailed proposal, project management, installation, commissioning and complete lifetime support.

Some smaller units can also be known as pluggable UPS. Up to 3KVA they are also known as ‘plug and play’ UPS – 3KVA UPS are the largest UPS that can be plugged into a standard 13 Amps supply.

Single phase UPS do not normally go above 20KVA because their input power requirement is sometimes impractical due to mains incomer limitations (at 15KVA a 100Amps mains supply would be required); or the cable sizing which would be required to handle the high current levels on both the input and output of the UPS.

They can be either mounted in either a 19’’ rack or be floor standing (it is important to specify which version is required); although some UPS are known as RT models. These can be configured in both rack and tower mode.

They can be as small as 300VA which would be sufficient to supply a conventional desk-top PC; up to 20KVA for a relatively small server room.
They are available in the following technologies, which denote the differing levels of voltage conditioning required;

Off-line UPS
These provide little, or no, voltage conditioning other than to provide some back-up power in the event of either: mains failure, long power sag or surge.

Line-interactive UPS
These also protect against under voltage and over voltage without going into battery mode.

On-line UPS
These are also known as ‘double conversion’ UPS and provide 100% voltage conditioning. They rectify the AC mains into a DC voltage which is connected to an inverter input to provide a good clean AC waveform for the UPS output.
