Three Phase
Voltage Stabilizers & Power Line Conditioners

At Ashley-Edison (UK) our Three-Phase AC Voltage Stabilisers continuously monitor the incoming mains supply. If the voltage rises or drops, they will automatically control the output voltage – ensuring the voltage reaching the load equipment always remains constant at the required requisite voltage. Inbuilt protection features also continuously safeguard that the load against harmful mains born high energy surges, spikes, and transients.

For less prevalent situations, where electrical noise is also an issue on-site, most models are also available as Power Line Conditioners offering an enhanced level of Transient Voltage Surge & Spike Suppression (TVSS) protection and delivering the added benefit of filtering out any electrical noise and interference present on the incoming utility supply – ensuring what is commonly referred to as a ‘CLEAN’ supply.

For General Commercial & Industrial Applications

Our feature-rich SVR (Servo Electronic) and ESR (Static Electronic) Three Phase  Voltage  Stabilisers are our most popular and cost-efficient offerings.

Suitable for 95% of all applications, SVR & ESR Stabilizers not only guard against voltage fluctuations they also offer protection against all too common harmful high-energy surges, transients, and voltage spikes.

With independent phase control as standard on all three phase ranges, the voltage on each phase will always remain stable irrespective of load unbalance, even in situations where a 100%  load imbalance may exist.
