VIX Series UPS Systems – Line Interactive Square Wave

The VIX Series UPS Systems are high value systems for entry level power protection.


The VI in VIX means Voltage Independent meaning the unit provides a degree of Automatic Voltage Regulation or AVR. The benefit of this is that it allows a greater input voltage swing before the unit reverts to battery operation. This increases battery life and increases uptime by preventing needless discharges.

The X in VIX means that the units are non-sine. We call them square wave, but others call them pseudo-sinewave, modified sine-wave, stepped sine-wave etc. A sine wave power supply is like you get from your normal mains supply. Electronically, a square wave is a lot easier produced and this reduces the cost of these systems when comparing to other technologies. However, this means that the VIX series should only be used for computer type power supplies.


The VIX1000 series UPS Systems are available in 1, 1.5, 2 & 3KVA models. These models are mainly intended for reseller and OEM channels.

The VIX3000 series is being phased out to be replaced with the VIX3000+ series. The VIX3000+ series has the advantage of LCD display across the range which is touch screen in operation. It also has a HID compliant USB port. VIX3000+ is available in 650VA, 1000VA and 2000VA models.

All the VIX series products are quiet in operation except for obvious audible alarms.  Higher powered (1.5KVA and above) units do contain fans, but these are only active when the unit is in an abnormal mode eg buck, boost or on battery.

The VIX2000 series is now obsolete.

Applications for VIX Series UPS Systems.

Any application that uses Switch Mode Power Supplies (SMPS). Examples are EPOS, Modems, Routers, PCs etc. Don’t use them on devices that have motors or transformers, as this may cause improper operation of the load and the UPS. However please note that some motor load systems such as door applications appear to work without issue with the VIX series.
