Automatic Voltage Stabilisers

Single & Three Phase

Servo Electronic Design

Constant & Automatic Voltage Regulation

Suitable for all electrical and electronic equipment, Ashley-Edison’s AC Voltage Stabilisers continuously monitor the incoming supply and automatically regulates the output to ensure the voltage reaching the load equipment always remains constant at the requisite voltage.

With inbuilt Transient Voltage Surge Suppression (TVSS), they also protect electrical and electronic load equipment against, all too common, harmful high-energy surges, transients and voltage spikes.

1KVA to 3,000KVA

Wide Input Voltage Tolerance up to ±40%

Precise Output Voltage Accuracy up to ±0.5%

< 1.5ms Response Time

3 Years Warranty Included

Step-less Voltage Regulation

Ashley Edison’s Servo Electronic Design delivers smooth and stabilised output voltage to the load, optimising the equipment’s life span and protecting your uptime.

Independent Phase Control

Independent phase voltage sensing and control ensures the individual phase voltages remain stable, regardless of load unbalance.

Unparalleled Inbuilt Protection and Control Features

When looking for quality voltage protection, Ashley-Edison’s market leading AC Voltage Stabilisers have repeatedly proven their durability and dependability in some of the world’s harshest and most demanding power environments.
