We supply, install and maintain UPS and Standby Generators.

We provide site surveys, a consultative approach to our solutions, and long term post sales support.  Our customer base comprises mostly medium to large size businesses in many different business sectors.

Every business; small or large, relies on computer systems to a greater or lesser degree.  Power protection equipment simply provides resilience of those critical systems in the event of a mains power outage.

A power cut can last from a few seconds to several hours and usually happens without warning, bringing the whole organization to an immediate halt.  Statistics have shown that in general we all experience on average one power cut per year, so it makes good business sense to prepare for it.

As every business has different power protection requirements, we offer a an individual  solution based on individual needs.

UPS designs come in three different types - Off-line, Line Interactive, and On-line.

Off-line and Line Interactive work in fundamentally the same way.  Power is supplied to the UPS, some 'power cleaning' is applied as it passes through the UPS and in the event of a power failure, a switch automatically operates to draw power from the battery bank.  When power is restored then the switch automatically returns to its normal position.

On-line design is very different.  The power coming into the UPS is converted from AC to DC, and runs in parallel with the battery bank.  On the output side, the power is re-converted back to AC. There is no switching, the battery simply starts to supply power as soon as the mains power disappears.  Also, the 'power cleaning' comes from the double conversion process, and is more effective than the other two types.
