The Automatic Voltage Conditioner (AVC) combines a rectifier, an inverter, a series compensation transformer and a monitoring system. It injects a corrective voltage in series with the supply to mitigate voltage sags (down to -40%) and swells (up to +30%) without interruption, and its power electronics can also compensate reactive power, harmonics and three-phase unbalance. The load receives a stable voltage, protecting sensitive processes from costly stoppages.
Typical uses: plants sensitive to voltage dips (petrochemicals, semiconductors, pharmaceuticals, automotive, textiles), end of long low-voltage lines with low voltage and unbalance, networks with high photovoltaic penetration, and road tunnels with long supply lines and fluctuating loads.
Key features
- Continuous, high-precision voltage regulation without interruption
- Phase-by-phase control, suitable for severely unbalanced loads
- Compensation voltage and regulation speed adjustable to user requirements
- Optional reactive power, harmonic and three-phase unbalance compensation
- Current limiting output: keeps compensating under overload without shutting down
- Overload, overcurrent, grid over/undervoltage, overtemperature, phase loss and frequency protection
- RS485 communication (4G and Wi-Fi supported), modular design and small footprint
