The A&E 10KVA Single Phase Special Servo Voltage Stabilizer (AESB50-D-10KVA) is a specialized "Ultra-Wide Input" power solution. While standard servo stabilizers often struggle when the voltage drops below 90V, this AESB50 model is engineered to pull and stabilize power from an incredibly low 50V.
Available at Kara.com.ng, this unit is the "heavy-lifter" for homes and offices in areas where the national grid is exceptionally weak.
A&E 10KVA Special Servo Price in Nigeria (2026 Update)
The "Special" designation refers to the extra-large copper transformer required to boost 50V up to 220V. This makes the unit significantly heavier and more expensive than the standard 90V or 100V models.
| Model Variant | Input Range | Estimated Price (2026) |
| AESB50-D-10KVA (Special) | 50V – 250V | ₦650,000 – ₦685,000 |
| AEST90-D-10KVA (Standard) | 90V – 260V | ₦390,000 – ₦450,000 |
| Relay 10KVA (AERB45) | 45V – 280V | ₦360,000 – ₦395,000 |
Selection Tip: If your neighborhood power is so dim that bulbs are barely orange and fans won't spin, the AESB50 is your best option. It provides the precision of a Servo motor (safe for Inverter ACs) with the recovery power usually only found in Relay models.
Key Specifications (AESB50-D-10KVA)
- Capacity: 10,000VA (10KVA) / Approx. 8,000W – 9,000W Max Load.
- Input Voltage Range: 50V – 250V AC (Ultra-Wide).
- Output Voltage: 220V ± 3% (Precision Servo Regulation).
- Technology: Motorized Servo Carbon Brush + 100% Copper Toroidal Transformer.
- Display: Dual Digital LCD (Input Voltage, Output Voltage, and Load status).
- Weight: Approx. 50.6kg (Indicative of high copper content).
- Protection: Over-voltage (246V±4V), Under-voltage, Overload, High-Temperature, and Short-circuit.
- Delay Feature: Short Delay (3–5 seconds) to prevent rapid power-cycle damage.
Why the "50V Special" is Worth the Investment
- Lowest Starting Threshold: Most servo stabilizers "trip" or shut down when the voltage drops below 90V to protect their internal motor. The AESB50 is built with a specialized transformer tap that allows it to stay active down to 50V.
- Safe for Inverter Technology: Modern Inverter Air Conditioners and high-end OLED TVs have sensitive motherboards. The "stepless" regulation of this servo model ensures they receive a smooth flow of power without the harsh "jumps" of relay stabilizers.
- Industrial Cooling: Because boosting 50V to 220V generates significant heat, this model features an Intelligent Auto Cooling Fan that adjusts its speed based on the internal temperature.
- Centralized Protection: At 10KVA, this unit is designed to be installed at your main Distribution Board (DB), protecting everything from your kitchen appliances to your bedroom ACs.
What Can This 10KVA Stabilizer Power?
In a typical 3-bedroom Nigerian apartment, this unit can support:
- Two 1.5HP Air Conditioners (Inverter types are highly recommended).
- One Large Double-Door Fridge + One Chest Freezer.
- 1HP Water Pumping Machine.
- Whole-Home LED Lighting and Fans.
- Washing Machine and Microwave (if used when one AC is off).
Maintenance & Installation Tips
- Cable Gauge: For a 10KVA load boosting from 50V, the current (Amperage) is very high. You must use a minimum of 10mm or 16mm Pure Copper cables. Using 6mm or aluminum-clad cables will cause the wires to melt.
- Placement: This is a "Desktop" (floor-standing) unit. Due to its weight (50kg+), do not attempt to mount it on a wall unless using heavy-duty industrial brackets. Place it in a dry, ventilated area.
- Service: Have a technician check the internal carbon brush every 2 years. Dust buildup on the copper tracks can cause the motor to "stutter," leading to voltage fluctuations.
Would you like me to check the availability of 16mm Pure Copper cables for your installation, or do you need a 15KVA model for a larger house?
