"15kVA of Pure, Stable Power – Vectronic AVR 15kVA Single Phase."
You've invested in powerful appliances – big air conditioners, deep freezers, industrial printing machines, salon equipment, bakery ovens, and water pumps. But what happens when the voltage drops dangerously low or spikes without warning?
Your equipment suffers. Motors overheat. Compressors fail. You pay thousands in repairs – or worse, replacements.
Meet the Vectronic AVR 15kVA (Single Phase) – a heavy-duty automatic voltage regulator engineered for Nigerian homes and businesses that demand serious power protection. Unlike small stabilizers that struggle with large loads, this 15kVA beast takes unstable input from 140V to 270V and delivers steady 220V ±5% output – even during the worst brownouts.
Perfect for: large homes, boutique hotels, small factories, event centers, churches, clinics, restaurants, cold rooms, printing presses, and workshops running on single-phase power.
Stop burning money on dead appliances. Start regulating.
| FeatureBenefit | |
| 15kVA / 12,000W true power rating | Supports heavy loads – multiple ACs (up to 5–6 units), large freezers, industrial equipment, or an entire small business. |
| Wide input voltage range: 140V – 270V | Operates during severe brownouts that shut down cheaper stabilizers. Keeps your equipment running when others fail. |
| Stable output: 220V ±5% | Safe, appliance-friendly voltage – protects motors, compressors, electronics, and sensitive equipment from damage. |
| Servo-motor controlled voltage correction | Fast, accurate, and silent – corrects voltage instantly without the clicking noises of relay-based stabilizers. |
| High-efficiency toroidal transformer | Runs cooler, quieter, and more efficiently than traditional EI-core transformers – up to 96% efficiency. |
| Digital LCD display + LED indicators | Real-time monitoring: input voltage, output voltage, load percentage, and fault status. No guessing – full visibility. |
| Overload capacity: 150% for 15 seconds | Handles motor startup surges (AC compressors, water pumps, elevators) without tripping. |
| Adjustable time delay (0–10 seconds) | Prevents servo stress during generator startup or grid fluctuations. Extends AVR lifespan. |
| Automatic bypass switch | If the AVR overloads or has an internal fault, it automatically switches equipment directly to utility power – zero extended downtime. |
| Full protection suite | Over-voltage, under-voltage, over-current, short circuit, and over-temperature protection. Automatic shutdown on critical faults. |
| Heavy-duty metal enclosure | Industrial build quality – fire-resistant, impact-resistant, and designed for Nigerian heat, dust, and humidity. |
| Wall-mountable or floor-standing design | Flexible installation options – mounts on a reinforced wall or sits on the floor. |
| Cooling fans with temperature control | Fans run only when needed – quieter operation and longer fan life. |
| Remote monitoring ready (RS-485 / Modbus – optional) | Integrate with building management systems or receive alerts remotely. |
| Business / FacilityWhy They Need It | |
| Large home (5–7 bedrooms) | Protects multiple ACs (4–6 units), refrigerators, deep freezers, entertainment systems, and water pumps. |
| Boutique hotel / lodge | Guest comfort depends on working ACs, TVs, fridges, and water supply – one voltage dip can ruin reviews. |
| Restaurant / canteen | Protects cold rooms, freezers, cooking equipment, and POS systems – food spoilage is expensive. |
| Small factory / workshop | Protects industrial sewing machines, printing presses, grinders, compressors, and other equipment. |
| Printing / photocopy shop | Sensitive printers and large photocopiers need stable voltage – prevents misalignments, errors, and costly reprints. |
| Salon / barbing shop (large) | Multiple dryers, clippers, flat irons, and ACs running simultaneously – voltage drops mid-service are embarrassing. |
| Event center / hall | Powers sound systems, lighting, ACs, and kitchen equipment without voltage sag during peak usage. |
| Church / religious center | Protects sound systems, projectors, ACs, and kitchen equipment – Sunday morning service must run smoothly. |
| Clinic / small hospital | Protects medical equipment, refrigerators for vaccines, ACs, and water pumps – patient care depends on stable power. |
| Cold room / freezer storage | Compressor motors are expensive. Undervoltage kills them fast. This AVR extends compressor life significantly. |
| Bakery / commercial kitchen | Industrial ovens, mixers, and proofers need consistent voltage for perfect results. No more burnt batches. |
| Water borehole / pumping station | Borehole pumps are costly to pull out and repair. Undervoltage protection saves thousands. |

Q: What is the difference between 15kVA and 15,000VA?
Nothing. kVA (kilovolt-ampere) and VA (volt-ampere) are the same unit. 15kVA = 15,000VA. For motor and compressor loads (inductive), actual usable wattage is roughly 80% of kVA – approximately 12,000 watts.
Q: How many air conditioners can a 15kVA AVR support?
Approximately 5–6 split AC units (1.5hp each) running simultaneously. If you have inverter ACs (which have gentler startup surges), you can connect even more. For accurate sizing, calculate total running watts: 1.5hp AC ≈ 1,200–1,500 running watts.
| AC SizeRunning WattsStartup Surge | ||
| 1.0hp | ~800W | ~2,400W |
| 1.5hp | ~1,200W | ~3,600W |
| 2.0hp | ~1,600W | ~4,800W |
| 2.5hp | ~2,000W | ~6,000W |
The AVR's 150% overload capacity handles startup surges easily.
Q: What other equipment can I connect?
Beyond ACs, you can connect:
Q: Can I use this AVR with my generator?
Yes – highly recommended. Many Nigerian generators (especially smaller or older units) produce fluctuating voltage. The Vectronic AVR stabilizes generator output before it reaches your equipment. The adjustable time delay prevents AVR hunting during generator warm-up.
Q: What is the difference between a servo AVR and a relay AVR?
| FeatureServo AVR (This model)Relay AVR (Cheaper models) | ||
| Correction | Smooth, continuous | Step-by-step (clicks) |
| Noise | Quiet | Clicking sounds |
| Accuracy | ±5% or better | ±8–10% |
| Durability | Longer lifespan | Relays wear out faster |
| Best for | Heavy loads, motors, compressors | Lights, fans, small TVs |
For 15kVA capacity, servo is the right choice.
Q: Do I need an electrician to install this AVR?
Yes – strongly recommended. This is a 15kVA unit drawing significant current. A qualified electrician will ensure:

Q: How much floor or wall space do I need?
Typical dimensions: 550mm (W) x 450mm (D) x 800mm (H) – about the size of a large suitcase or small mini-fridge. Weight: 50–70kg. Requires:
Q: Does the AVR consume electricity when my equipment is off?
Yes, a small amount (typically 150–400 watts) for the control system, transformer idle losses, and cooling fans. For most businesses, this is negligible compared to total consumption. During extended shutdowns (weeks), you can install an isolator switch to completely power off the AVR.
Q: What is the typical lifespan of this AVR?
With proper installation, moderate loading (not exceeding 15kVA), and basic annual maintenance (cleaning dust, checking connections) – 8–12 years minimum. The servo motor and carbon brushes are wear items that may need replacement every 5–7 years; these are available from Vectronic Nigeria.
Q: Can I connect a UPS after this AVR?
Yes – and this is an excellent setup. The AVR cleans the voltage before it reaches the UPS, which means:
