On a hill in Swaziland in 1996

On a hill in Swaziland in 1996, a customer of ours installed an automatic voltage stabilizer. Our core business is UPS (uninterruptible power supply) sales and service, but in order to satisfy our customer, I sourced the voltage stabilizer. I didn’t realize that I would also have to commission it on a hill in Swaziland. I had to get there in a 4x4 bakkie. Since then I have made enquiries as to the voltage stabilizer’s health, and it is still working. Since 1997 we have imported a full range of single phase and three phase automatic voltage stabilizers (AVS). With excellent results.

You are probably wondering why you should want or need an AVS. There are several reasons, including:-

1. If your UPS’s are using the batteries when the power is present (beeping occasionally), your voltage is out of range of your UPS’s and the AVS will solve that if installed between the utility connection (Escom in our case) and your UPS’s.

2. If you have surge arrestors installed in your distribution board (DB), but you are still losing devices and/or equipment. The problem is probably caused by sustained or long high or low voltage and the AVS will solve this.

3. You require a constant voltage for your process or plant such as plastic welding, printing etc and the AVS will give you this stability.

The advantages of an AVS are among others:

Very reliable over a long term

Very efficient and has no power devices

Runs cool

Relatively inexpensive
