The A&E 100KVA Three-Phase Servo Voltage Stabilizer (AES3B-D-100KVA) is an industrial-grade power protection system designed for heavy-duty commercial and manufacturing applications. This unit acts as a central power regulator, balancing three independent phases to ensure your facility receives a consistent 380V (Phase-to-Phase) or 220V (Phase-to-Neutral) output.
Available at Kara.com.ng, this model is built with the SBW (Column Type) compensation structure, which is the gold standard for handling high-capacity inductive loads without de-rating.
A&E 100KVA 3-Phase Servo Price in Nigeria (2026 Update)
Given the massive copper content (Gross Weight: ~327kg) and the complexity of the three independent servo-motor systems, this is a significant capital investment.
| Model Variant | Input Range | Estimated Price (2026) |
| AES3B-D-100KVA (Standard) | 304V – 456V | ₦5,700,000 – ₦6,000,000 |
| AESBW-DF-100KVA (Digital Fan) | 304V – 470V | ₦3,950,000 – ₦4,500,000 |
| A&E 150KVA 3-Phase Servo | 304V – 456V | ₦7,800,000 – ₦8,300,000 |
Selection Tip: The AES3B-D model is often the more rugged, cabinet-style unit designed for continuous industrial use. The DF models usually feature enhanced digital cooling fans but check the specific transformer winding material (Copper vs. Aluminum) as that accounts for the price variation.

Why 100KVA Three-Phase is Vital for Industry
- Independent Phase Correction: In many Nigerian industrial zones, one phase may be "weak" while others are "strong." This unit regulates each phase separately, preventing Phase Imbalance, which is the #1 cause of motor burnout in central ACs and industrial pumps.
- Inductive Load Specialist: Engineered to handle the massive "Inrush Current" required to start large motors (e.g., elevators, printing presses, and industrial chillers).
- Digital Control Technology: The microprocessor-controlled system ensures zero "voltage flicker," which is essential for sensitive Medical Lab equipment, CNC Machines, and Data Center Servers.
- Bypass System: Typically features a manual bypass switch, allowing maintenance on the stabilizer without interrupting power to the entire facility.
What Can This 100KVA Stabilizer Power?
A 100KVA central unit is the primary guardian for:
- Large Office Complexes: Managing 40+ Air Conditioners and massive server racks.
- Hotels & Hospitals: Protecting elevators, central chillers, and X-ray/MRI suites.
- Manufacturing Plants: Powering CNC machines, plastic extruders, and printing presses.
- Residential Estates: Acting as a central buffer for a cluster of 4–6 luxury duplexes.
Maintenance & Installation Tips
- Cable Requirement: For a 100KVA 3-phase load, you must use a minimum of 50mm or 70mm 4-Core Armoured Copper cables. Using undersized cables at this capacity is a severe fire hazard.
- Ventilation: This is a heavy-duty cabinet. Ensure it has at least 1 meter of clearance from walls in a dedicated electrical room to allow the industrial cooling fans to circulate air.
- Phase Sequence: Have a certified engineer verify the phase sequence (L1, L2, L3) during installation. Reversing the phases can cause 3-phase machinery to operate backward.
