Size matters. we build up to 3,000kva.

Boasting a massive capacity range, our custom built Magnetic Induction Automatic Voltage Stabilisers cater up to 3,000KVA loads along with a wide input swing of up to ±30% voltage tolerance.

magnetic induction, brushless technology.
A maintenance-free solution.

Ashley Edison Magnetic Induction Voltage Stabilisers utilises a rotor and stator design principle to amplify or reduce the magnitude of the voltage in a series transformer winding, regulating and maintaining a constant output voltage. This concept results in a highly reliable and virtually maintenance-free voltage stabilisation solution.

oil immersion cooling

Significantly enhances performance and cooling efficiency for industrial-grade voltage regulation and power protection.

Also available in Single Control Module.

For the load-balanced 3 Phase 3 Wire systems, the IVS Magnetic Induction Series is an ideal economical option and also in terms of physical size, a highly compact solution.

Technical Features


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

Broad input voltage tolerance

From ±10% up to ±30% input voltage swing.

Inbuilt High Overload Capability

Ideal for loads with an inherent initial high current draw on startup.

precision voltage regulation

Output voltage accuracy ±1.5%.

Phase Failure & Reversal Protection

Audible alarm in the event of phase failure or reversal.


Protects loads against harmful high-energy surges, transients and spikes.

Over / Low Voltage alarm

Ability Audible alarm in the event of the supply voltage going outside the input voltage window.

Lightning Surge protection

Protection against extremely high voltage surges and transients caused by lightning strikes on the supply line.

volt-free remote monitoring contacts

With RS-485 interface or Mimic Panel option.

cloud-based data system analysis

Real-time wireless applications for Measurement and Verification of energy and resource consumption.
