The A&E 150KVA Three-Phase Servo Voltage Stabilizer (AESBW-D-150KVA) is a high-capacity, industrial-grade power solution designed for large-scale operations. Unlike residential single-phase units, this "SBW" (Column Type) stabilizer is engineered to handle the massive electrical loads of entire factories, hotels, hospitals, or high-rise office complexes.
Available at Kara.com.ng, it uses independent three-phase regulation to ensure that even if one phase is significantly lower than the others, the output remains a perfectly balanced 380V.
A&E 150KVA 3-Phase Servo Price in Nigeria (2026 Update)
As an industrial asset, the price of a 150KVA unit is influenced by the current cost of high-grade copper and the complexity of its triple-servo control system.
| Model Variant | Technology | Estimated Price (2026) |
| AESBW-D-150KVA (Servo) | 3-Phase Motorized Servo | ₦6,080,000 – ₦8,300,000 |
| A&E 100KVA 3-Phase | 3-Phase Motorized Servo | ₦5,980,000 – ₦6,500,000 |
| A&E 200KVA 3-Phase | 3-Phase Motorized Servo | ₦9,200,000 – ₦10,500,000 |
Selection Tip: This is a heavy-duty cabinet unit weighing approximately 327kg. It is typically delivered on a pallet and requires a dedicated, well-ventilated electrical room for installation.

Why 150KVA is Necessary for Industrial Sites
- Independent Phase Correction: In industrial settings, one phase might be heavily loaded (e.g., by single-phase ACs) while another is light. This unit stabilizes each phase separately, preventing the "Phase Imbalance" that often burns out expensive 3-phase motors in elevators and industrial chillers.
- Inductive Load Handling: It is built to survive the massive "Inrush Current" generated when large motors start up. This makes it ideal for Factories, Workshops, and Data Centers.
- Microprocessor Precision: The digital control board monitors the grid in real-time, adjusting the carbon brushes with high speed and precision to ensure zero "voltage flicker."
- Bypass System: Industrial models usually feature a Manual/Automatic Bypass, allowing you to switch to raw grid power for maintenance without shutting down the entire facility's operations.
What Can This 150KVA Stabilizer Power?
A 150KVA central unit is a primary power guardian for:
- Large Hotels & Hospitals: Powering central cooling, elevators, and medical imaging (MRI/CT).
- Manufacturing Plants: Protecting CNC machines, plastic extruders, and printing presses.
- Large Office Towers: Managing 50+ Air Conditioners and massive server rooms.
- Residential Estates: Acting as a central buffer for a cluster of 5–10 luxury duplexes.
Maintenance & Installation Tips
- Wiring: For a 150KVA load, you must use heavy-duty 70mm or 95mm 4-Core Armoured Copper cables. Using undersized cables at this capacity is a major fire hazard.
- Cooling: The unit generates significant heat under heavy load. Ensure it has at least 1 meter of clearance from walls to allow the industrial cooling fans to circulate air effectively.
- Servo Brush Check: Because of the heavy mechanical work, the carbon brushes should be inspected by a qualified engineer every 12 months to ensure they haven't worn down or accumulated carbon dust on the copper tracks.
