"120kVA of Industrial Power Precision – Vectronic 120kVA 3-Phase Automatic Voltage Regulator."
In the world of industry, voltage is everything. Too low, and your motors overheat, struggle, and burn out. Too high, and your sensitive electronics fry instantly. Unbalanced between phases, and your equipment shakes, vibrates, and fails prematurely.
For Nigerian businesses running on 3-phase power – manufacturing plants, cold rooms, hospitals, data centers, telecom base stations, and large commercial complexes – unstable voltage isn't an inconvenience. It's a profit killer.
Introducing the Vectronic 120kVA (3-Phase) AVR – a heavy-duty, industrial-grade automatic voltage regulator engineered for the brutal realities of Nigeria's power grid. This machine takes unstable 3-phase input from 170V to 480V phase-to-phase and delivers rock-solid 380V/400V ±3% output – independently correcting each phase.
Whether you're protecting a 120kVA diesel generator, an industrial cold room, a hospital's imaging suite, or an entire manufacturing production line – the Vectronic 120kVA AVR ensures your equipment runs safely, efficiently, and continuously.
Stop replacing burnt motors. Stop losing production hours. Start regulating.

Q: What is the difference between 120kVA and 120kW?
For an AVR, kVA is the apparent power rating. kW (real power) = kVA × power factor (typically 0.8 for industrial loads). So 120kVA × 0.8 = 96kW of usable power. This is standard and sufficient for most industrial equipment.
Q: How much equipment can a 120kVA 3-phase AVR support?
A 120kVA (96kW) AVR can support approximately:
| Equipment TypeTypical PowerQuantity Supported | ||
| Large cold room compressor (20hp) | ~18kVA | 5–6 units |
| Large cold room compressor (30hp) | ~27kVA | 3–4 units |
| Industrial AC (10hp) | ~9kVA | 10–12 units |
| CNC machine (medium) | ~15kVA | 6–8 units |
| Injection molding machine | ~25kVA | 3–4 units |
| Water pump (50hp) | ~45kVA | 2 units |
| Server rack (full) | ~10kVA | 8–10 racks |
| MRI machine (medical) | ~30kVA | 3 units |

Q: What is the difference between an AVR and a UPS at 120kVA scale?
| AspectAVR (This product)UPS (120kVA) | ||
| Voltage regulation | ✅ Yes | ✅ Yes |
| Battery backup | ❌ No | ✅ Yes (5–15 min typical) |
| Price | Significantly lower | Very expensive |
| Maintenance | Lower (no batteries) | Higher (battery replacement every 3–5 years) |
| Best for | Voltage fluctuation protection | Blackout ride-through + voltage protection |
Most large Nigerian facilities use BOTH: AVR → UPS → Generator. The AVR cleans power before it reaches the UPS, extending UPS battery life and preventing nuisance transfers.
Q: What input voltage does the Vectronic 120kVA AVR accept?
The unit accepts 3-phase input from 170V to 480V (phase-to-phase). It is designed for Nigerian standard of 380V/400V/415V (50Hz) but operates safely across the full range. Below 170V or above 480V, the AVR shuts down automatically to protect itself and your equipment – then auto-restarts when voltage returns to safe range.
Q: Does this AVR work with my generator?
Absolutely – and this is one of its primary use cases. Many Nigerian industrial generators produce voltage that fluctuates by ±15–20%, especially under varying loads. The Vectronic AVR stabilizes this before it reaches your equipment. The adjustable time delay prevents AVR hunting during generator warm-up or load changes.
Recommended setup: Generator → AVR → Distribution Board → Equipment.
Q: What is the physical size and installation requirements?
Typical dimensions: 1000mm (W) x 700mm (D) x 1600mm (H) – roughly the size of a large industrial refrigerator. Weight: 400–550kg depending on exact configuration.
Installation requirements:

Q: What is phase imbalance and why is it dangerous at industrial scale?
Phase imbalance means L1, L2, and L3 have different voltages (e.g., L1=210V, L2=195V, L3=220V). Causes:
Dangers at industrial scale:
The Vectronic 120kVA AVR corrects each phase independently, eliminating dangerous imbalance instantly.
Q: How efficient is the Vectronic 120kVA AVR?
Up to 97% efficiency at full load – meaning only 3% of input power is lost as heat. For a 120kVA unit under heavy load, that's approximately 3.6kW of heat dissipation – requiring proper ventilation in the installation room (air conditioning or forced air extraction recommended for enclosed spaces).
Q: Can I install this AVR outdoors?
The standard unit is IP20 (indoor use only, protected against solid objects over 12mm). For outdoor or dusty industrial environments, we recommend the IP54-rated enclosure (dust-tight and splash-proof). Chat with our team for outdoor installation requirements.
Q: What is the typical lifespan of a 120kVA industrial AVR?
With proper installation, regular maintenance (cleaning filters, checking connections, testing relays/servos annually), and operation within rated limits – 10–15 years minimum. Many industrial AVRs last 20+ years with proper care.

Q: How do I size an AVR for my facility?
You'll need to calculate your total connected load in kVA. Steps:
Example: If your total connected load is 100kVA, diversity factor 0.7 = 70kVA, plus 20% safety margin = 84kVA – the 120kVA AVR is appropriately sized (provides comfortable headroom).
This is complex. Chat with our team for a free professional load assessment – we'll send an engineer or remote consultant to help you size correctly.
Q: What is the approximate price of a Vectronic 120kVA 3-Phase AVR?
Pricing varies based on:
For an accurate, up-to-date quote, chat with us directly – we provide competitive pricing for industrial clients and can offer payment plans or leasing options for qualifying businesses.
Q: Can this AVR protect against lightning surges?
The AVR has built-in surge protection for typical industrial voltage spikes. For direct or nearby lightning strikes, we strongly recommend installing additional Type 1 or Type 2 surge arresters upstream of the AVR. Chat with our team for lightning protection recommendations specific to your location.
Q: Does the AVR require input from my generator's AVR (automatic voltage regulator)?
No. The Vectronic AVR is completely separate. Your generator already has a small internal AVR to regulate its output. The Vectronic AVR further stabilizes that output – think of it as double protection. It's compatible with all major generator brands (Cummins, Perkins, FG Wilson, SDMO, Mikano, etc.)
Your industrial equipment is a multi-million naira investment. Protect it like one.
