VR Series
Low Cost
Single Phase AC Voltage Stabilisers / Power Line Conditioners
0.5 to 5kVA
VR Series - Single Phase
Voltage Stabilizers / Power Conditioners - 0.5 to 5kVA
VR Series Static Voltage Stabilisers and Power Line Conditioners are specifically designed to meet the requirements of today’s modern loads, being feature rich and virtually maintenance free static mains control solutions.
They ensure the availability of a constant voltage at a level that always meets the design requirements of the load equipment.
In addition, they safeguard against all too common everyday transient voltages and spikes – typically introduced into the mains supply by nearby disturbances resulting from peak power demands or stop/start operation of electrical machinery.
Capable of supporting all electrical and electronic modern office and general household appliances (including air conditioners, computers, fridges, TV, satellite and any other electrical loads), models are available for situations where the incoming mains utility supply is between 140V to 270V (F Models) or, for more challenging power environments, 80V to 270V (G Models).

Standard Features include:
 | Automatic Voltage Regulation: Suitable for all electrical and electronic equipment, VR Series Voltage Stabilisers / Conditioners continuously monitor the incoming supply. Should the incoming voltage rise or drop, the Stabilisers will automatically control the output to ensure the voltage reaching the load equipment remains within the load equipment’s intended requisite input voltage window. |
