Voltage Stabiliser Swing Ranges

In 2017 we enhanced our product design and introduced a new part numbering system – if you need an equivalent replacement unit, take a look at the below easy look-up table.

Our TS series provides alternative tappings that give three selectable input swings within the total input range 50:50, 70:30 or 30:70. They allow for changes in site/load conditions in years to come, without the need and expense of changing the entire equipment.  This future-proofs our systems when it comes to your long-term AC Voltage control requirements.

Need help in selecting the correct swing range for your requirements? Please contact us and our engineering team will be happy to assist.

What swing range do I need?

Our most commonly deployed system is the R30, providing a total input variation of +/-30%, which can be set to below input swings:

Tap A = -21% to +9%
Tap B = +/- 15%
Tap C = -9% to + 21%

In remote locations or regions/countries where the supply infrastructure is less robust, then greater variations may be required to suit.

  • Higher swing ranges are available, please contact us for more information.
