eST – Static Voltage Stabilisation Unit

14951669_ml - Version 2

The eST Static voltage stabiliser system uses the latest generation high speed microprocessor controlled thyristors to provide plant and equipment with stabilised voltage and is designed for use in areas where the electrical supply grid is prone to sudden changes such as spikes or sags. Eliminating these sudden changes in supply voltage reduces the risk of premature failure consistently operating electrical loads within their design voltage range.

The eST Stabiliser benefits from industry leading voltage detection and response times of <300 mS to maintain voltage and protect equipment from an ever more increasingly unstable electrical supply system.
