Vener 7 · Three-phase
Three-Phase AVRs, 10-3000 kVA
For factories, hospitals, data centers and commercial buildings. Each phase is servo-controlled independently, essential on the East African grid where phase imbalance is routine. Available in air-cooled (10-600 kVA) and oil-cooled (up to 3000 kVA) configurations.
Key features
- Independent servo control on each of the three phases
- Handles severe phase imbalance without derating
- Input bands: 320-460 V or 340-460 V (configurable)
- Output: 400 V ± 1% per phase, line-to-line
- Response time: 10-20 ms per phase
- Air-cooled or oil-cooled depending on capacity
