The A&E 5KVA Single Phase Servo Voltage Stabilizer (AESB100-W-5KVA) is a high-precision power management solution designed for the specific needs of the Nigerian power grid. This "100V-260V" model strikes a balance between performance and affordability, making it one of the most popular central stabilizers for 1–2 bedroom apartments or modern office setups.
Available at Kara.com.ng, it provides a consistent 220V ±3% output, ensuring that sensitive electronics like Inverter ACs and Smart TVs are shielded from the "surges" and "brownouts" common in Lagos and other major cities.
A&E 5KVA Servo 100-260V Price in Nigeria (2026 Update)
The AESB100-W is positioned as the standard "Wide Range" model. It is more affordable than the 50V or 80V "Extreme" models but offers significantly better precision than cheaper relay-based units.
| Model Variant | Input Range | Estimated Price (2026) |
| AESB100-W-5KVA (Wall Mount) | 100V – 260V | ₦224,500 – ₦255,000 |
| AEST90-W-5KVA (Precision) | 90V – 260V | ₦265,000 – ₦298,500 |
| AESG50-W-5KVA (Extreme Low) | 50V – 260V | ₦315,000 – ₦365,000 |
Buying Tip: If your area has "decent" light that rarely drops below 100V (where fans still spin at a moderate speed), the AESB100-W is the most cost-effective choice. If your light is frequently "dim" (bulbs just glowing orange), consider the 80V or 50V models instead.
Key Specifications (AESB100-W-5KVA)
- Capacity: 5,000VA (5KVA) / Approx. 4,000W – 4,500W Max Load.
- Input Voltage Range: 100V – 260V AC.
- Output Voltage: 220V ± 3% (High-precision servo regulation).
- Technology: Motorized Servo Carbon Brush + 100% Copper Toroidal Transformer.
- Mounting: Wall-Mounted (Saves floor space and improves safety).
- Display: Dual Digital LCD (Real-time monitoring of Input and Output voltage).
- Efficiency: >95% (Energy efficient with minimal heat loss).
- Protection: Over-voltage (246V±4V), Under-voltage, Overload, High-Temperature, and Short-circuit.
Why Choose the AESB100-W Servo Model?
- Ideal for Inverter Appliances: Unlike relay stabilizers that "click" and jump in 10V–20V steps, the servo motor adjusts smoothly. This is critical for Inverter Air Conditioners and Inverter Refrigerators, which can have their circuit boards damaged by sudden voltage jumps.
- Full Capacity Output: A&E Dunamis uses high-quality copper windings, ensuring the unit can actually deliver its rated 5KVA capacity without overheating or "fusing" under heavy load.
- Space-Saving Design: The wall-mount design is perfect for Nigerian flats. It keeps the heavy unit off the floor, away from dampness and out of reach of children.
- Quiet Operation: At under 50dB, the motorized adjustment is much quieter than the loud "clacking" sounds of relay stabilizers, making it suitable for installation near bedrooms or quiet offices.
What Can This 5KVA Stabilizer Power?
A 5KVA Servo unit is the "sweet spot" for small to medium households. It can comfortably power:
- One 1.5HP or 2HP Air Conditioner (Inverter types preferred).
- Large Double-Door Fridge and a Chest Freezer.
- Whole-House Lighting (LED) and Multiple Fans.
- Home Theater System, 65-inch Smart TV, and Decoder.
- Washing Machine (if the AC is turned off during the cycle).
Maintenance & Installation Tips
- Wiring: Use a minimum of 6mm or 10mm Pure Copper cables. Avoid "mixed" or aluminum cables as they increase resistance and can cause the stabilizer terminals to melt.
- Digital Monitoring: Occasionally, check the input voltage on the display. If you see the input consistently below 100V, the stabilizer will "trip" to protect itself; this is a sign you may need a wider-range (50V/80V) model for your area.
- Technician Visit: Every 2 years, have a technician blow out the dust from the vents. Dust on the internal copper tracks can cause the servo brush to stick, leading to "Output High" errors.
