I started a UPS manufacturing company in 1992

“I started a UPS manufacturing company in 1992, spent 2 years improving the UPS and did it so well that the units are still supporting critical installations. Manufacturing is not an option anymore, but we were careful when we first imported the current range in 2006 and you can have the same reliability by calling us for your UPS requirements or UPS service requirements”

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

What experts don’t want you to know about UPS’s (uninterruptible power supplies)

On-line UPS’s use power to charge the battery and then operate the inverter.

This power is paid for by you the user of the UPS.

This power, used by the UPS to protect and support your computer and equipment is between 5 and 20 % of the power used.

A line interactive UPS uses less power, because the inverter does not operate unless there is a power failure.

A line interactive UPS is generally cheaper than an on-line unit in price and in running costs.

A line interactive UPS is generally smaller than an on-line UPS,

An on-line UPS has a more stable output than a line interactive unit.

Most modern on-line UPS’s do not have isolation between the input power and the output power.

If the input is not isolated from the output, the equipment connected to a UPS can be affected by noise and distortion of the neutral line.

Most equipment including PC’s do not require a sinusoidal (sine) waveform as the power supply converts the waveform to DC (direct current).

Batteries are an essential part of any UPS system and should be replaced every 3 to 5 years (depending on supply conditions, this could even be sooner) unless the batteries are rated at a higher life expectancy.

Sometimes it will cost 60% of a small UPS’s cost to replace the battery, but this could still be worth doing due to the higher specification of the replacement battery.
