AVE - Automatic voltage equalizer


AVE Fixed is a more cost-friendly solution but can still pack a punch. It uses fixed high-quality isolation transformers with PLC controlled variable tapping, which makes an instantaneous correction to any phase voltage imbalance. Any steady-state voltage imbalances will be corrected with the variable tapping functionality, making it capable of correcting a 100% voltage imbalance (fault condition).

Due to its roughed design transformers, the unit requires very little maintenance. It comes with an advanced integrated power quality analyzer with access through a remote web server and cloud solution. Unit Control and status information are obtainable from a local HMI panel.

Available voltage classes from 250 Vac – 690 Vac and transformers sizes up to 6000 KVA.


AVE optimizes your electrical network efficiency to save energy, protect assets, and save costs.

AVE Fixed:

1) Reduces phase voltage imbalance

2) Prevents phase angle differential

3) Eliminates transients and voltage spikes (lightning strikes)

4) Prevents Arc flash

5) Prevents Phase voltage instability

6) Reduces voltage harmonics (Phase – Ground)

7) Reduce waveform distortion

8) Eliminates noisy ground reference and frequency instability

9) Prevents arcing ground faults

10) It provides an excellent and stable ground reference for power system stability to ensure optimal operation of control systems without interruption.
