Vener 7 Voltage Regulators
Servo-controlled across the full range, with Nairobi support. Browse by phase, cooling method or size, or use the sizing tool to match your load.
How to choose
Every Vener 7 unit is servo-controlled. Two questions narrow it down: how your supply is wired, and how the unit sheds heat.
1. Single-phase or three-phase?
Homes, shops and most loads under 30 kVA run on a single-phase 230 V supply. Factories, hospitals and anything above 30 kVA are almost always three-phase 400 V. Not sure? It is on your Kenya Power meter, or we can check on a call.
2. Air-cooled or oil-cooled?
Air-cooled is the default indoors up to 600 kVA, no fluids, easy to service. Oil-cooled suits larger or continuous-duty sites that run hot, with outdoor-cabinet options. Above 600 kVA, oil-cooled is the usual choice.
The full range
Single-Phase AVRs
For homes, small shops, workshops and single-phase machinery. Servo-controlled regulation with ±1% output tolerance. Natural air-cooled, indoor installation.
- Capacity 3-30 kVA
- Input range 180-270 V
- Output 230 V ± 1%
- Response time under 10 ms
- Air cooled, silent operation
Three-Phase AVRs
For factories, commercial buildings, hospitals and most industrial loads. Individually servo-controlled per phase, handles phase imbalance common on Kenyan supply.
- Capacity 10-3000 kVA
- Input bands 320-460 V or 340-460 V
- Output 400 V ± 1% per phase
- Handles phase imbalance independently
