Introduction to Vectronic 200kVA 3-Phase AVR

"200kVA of Industrial Might. Zero Voltage Compromise. Vectronic 200kVA 3-Phase AVR."

Your factory floor is a symphony of精密 motion – large compressors humming, injection molding machines cycling, CNC spindles whirring, conveyors rolling. But one unstable voltage note can shatter the entire performance.

A brownout below 180V stalls production lines. A sudden spike fries million-naira control boards. Phase imbalance silently eats away at motor lifespan, reducing years of life to months.

For heavy industrial operations running on massive 3-phase power – large manufacturing plants, industrial cold storage complexes, teaching hospitals, data centers, telecom hubs, and major commercial developments – voltage instability isn't a technical annoyance. It's a direct attack on your bottom line.

Meet the Vectronic 200kVA (3-Phase) Automatic Voltage Regulator – a heavy-industrial, mission-critical power fortress engineered for Nigeria's most demanding environments. This giant takes unstable 3-phase input from 170V to 480V phase-to-phase and delivers rock-solid 380V/400V/415V ±3% output – with independent closed-loop servo correction on each phase.

Whether you're protecting a 200kVA generator, a fleet of 75–100hp industrial compressors, a hospital's entire imaging department, a tier-3 data center, or an entire manufacturing wing – the Vectronic 200kVA AVR is the ultimate armor for your most valuable assets.

Stop losing production hours. Stop replacing capital equipment. Command your power.

Features & Benefits

FeatureBenefit
200kVA / 160kW true 3-phase rating	Powers massive industrial loads – entire production lines, multiple 75hp compressors, hospital imaging suites, data center pods, and large commercial complexes.
Wide 3-phase input range: 170V – 480V phase-to-phase	Keeps operating during severe brownouts that cripple lesser AVRs. Your facility stays online when voltage drops dangerously low – common in Nigerian industrial zones with overloaded transformers.
Precise output: 380V/400V/415V ±3% (software selectable)	Delivers laboratory-grade voltage stability – protects sensitive PLCs, VFDs, medical imaging equipment (MRI/CT), servers, and precision industrial controllers.
Independent 3-phase servo-motor correction with heavy-duty copper-wound toroidal transformers (per phase)	Each phase regulated individually with dedicated servo motor and toroidal transformer. Eliminates phase imbalance – critical when utility supply is severely unbalanced (e.g., L1=195V, L2=185V, L3=230V), a common issue in Nigerian industrial zones.
Premium copper windings (standard – not aluminum)	Superior conductivity, higher efficiency (>97.5%), cooler operation, and significantly longer life (20+ years) than aluminum alternatives. Worth the investment for critical infrastructure.
Ultra-fast voltage correction: ≤ 8ms per volt	Near-instantaneous correction during rapid grid fluctuations or generator load changes. Your equipment never experiences dangerous voltage swings – even during lightning-fast dips.
Advanced digital microprocessor with 10-inch full-color LCD touchscreen	Complete real-time visibility: Input voltage (L1-L2, L2-L3, L3-L1, plus phase-to-neutral), output voltage, load current per phase (Amps), load percentage (kVA per phase and total), frequency (Hz), internal temperature, fan status, and fault history with time/date stamps. Full diagnostics without a technician.
High-visibility LED status panel	Quick visual checks from across the factory floor – green (normal), yellow (regulating), red (fault), blue (communications active).
Automatic bypass switch with heavy-duty contactors + manual override	If the AVR overloads or has an internal fault, the system automatically switches equipment directly to utility/generator power – zero extended downtime. Manual bypass enables maintenance without shutting down production.
Programmable time delay (0–60 seconds)	Prevents servo and contactor stress during generator startup or grid flapping. Extends AVR lifespan – critical for generator-fed facilities in Nigeria.
Massive overload capacity: 150% for 60 seconds, 200% for 12 seconds, 300% for 3 seconds	Handles enormous motor startup surges (large compressors, conveyors, extruders, injection molding machines, pumps) without tripping or voltage drop.
Full industrial protection suite	Over-voltage, under-voltage, over-current, short circuit, over-temperature, phase loss, phase sequence reversal, surge, spike, and harmonic distortion protection. Automatic shutdown and loud audible alarm on critical faults.
Phase loss + phase sequence reversal protection (sub-50ms response)	Prevents catastrophic motor damage if one phase disappears or phases are wired incorrectly. Shuts down safely within milliseconds and alerts operator.
Heavy-duty industrial steel enclosure with reinforced frame (IP20 standard, IP54 optional)	Dust-resistant, impact-resistant, vibration-resistant – built for Nigerian factory floors, generator rooms, and harsh environments. Floor-standing freestanding cabinet with lockable tempered-glass front door, rear access panels, forklift pockets, and lifting eyes.
Redundant intelligent cooling fans (N+1 configuration – 4 fans, 3 required)	Variable-speed fans ramp up only when needed – quieter operation, longer fan life, lower energy consumption. Redundancy ensures cooling continues if any single fan fails.
RS-485 / Modbus RTU / Modbus TCP (Ethernet) / SNMP communication ports (standard)	Remote monitoring and integration with BMS, SCADA, PLCs, generator controllers, and network management systems. Real-time voltage alerts sent to your phone, email, or control room.
6 configurable dry contact relay outputs	Connect to external sirens, flashing lights, building automation systems, or remote annunciator panels for immediate fault notification anywhere in your facility.
Anti-condensation heaters with digital humidistat (optional – strongly recommended for coastal areas)	Prevents internal moisture buildup – critical for facilities in Port Harcourt, Calabar, Warri, Bayelsa, and Lagos Island.
Per-phase manual voltage adjustment knobs with digital fine-tuning	Allows technician to fine-tune output voltage – useful for equipment with specific voltage requirements, commissioning, or compensating for long cable runs.
Comprehensive data logging (90 days internal memory, expandable via SD card/USB)	Records voltage history (input/output per phase, load per phase, frequency, temperature, fault events) over days/weeks/months – invaluable for troubleshooting, warranty claims, insurance claims, or proving grid issues to your DisCo. Exportable to CSV/Excel.
True RMS sensing with wide bandwidth	Accurate voltage and current readings even when grid power has significant harmonic distortion (THD up to 15%) – common with generator power, VFDs, rectifiers, and UPS systems.
Soft-start capability for large motor loads	Gradually ramps up voltage when starting large motors – reduces inrush current stress on the AVR, contactors, breakers, and your equipment.
Remote emergency shutdown (ERS) input	Connect to facility emergency stop system – instantly shuts down AVR output during emergencies for personnel safety.
Power factor monitoring (display only – not correction)	Monitor facility power factor in real-time – helps identify when power factor correction capacitors are needed.
Energy consumption metering (kWh accumulated)	Track energy usage through the AVR – useful for sub-metering and energy management programs.
