The A&E 20KVA Single Phase Servo Voltage Stabilizer (AESB80-D-20KVA) is an ultra-wide input, industrial-grade "Desktop" (floor-standing) power solution. While the standard AEST90 series starts at 90V, this AESB80 flagship model is specifically engineered to pull and stabilize power from an incredibly low 80V, making it the absolute "Gold Standard" for luxury homes and offices in areas with notoriously poor grid power.
Available at Kara.com.ng, this unit is heavy-duty, weighing approximately 176kg due to its massive 100% copper dual-transformer system.
A&E 20KVA Servo 80V-260V Price in Nigeria (2026 Update)
Given its specialized "Extreme Wide Range" components and massive copper content, the AESB80-D is a premium investment for centralized power protection.
| Model Variant | Input Range | Estimated Price (2026) |
| AESB80-D-20KVA (Floor Standing) | 80V – 260V | ₦1,282,300 – ₦1,350,000 |
| AEST90-D-20KVA (Standard) | 90V – 250V | ₦1,150,000 – ₦1,250,000 |
| A&E 20KVA Relay Model | 45V – 280V | ₦560,000 – ₦680,000 |
Selection Tip: The AESB80-D is a "Cabinet" type unit. Because of its weight (176kg), it is built on wheels. Do not attempt to wall-mount this specific model; it is designed for floor placement in a ventilated generator house or electrical room.

Why the AESB80-D is the Ultimate Power Guardian
- 80V Low-Voltage Performance: In many parts of Nigeria, voltage drops so low that standard stabilizers simply cut off. This unit continues to provide a perfect 220V even when the incoming line is at a "dim" 80V.
- Dual Compensation Transformer: This model uses a more advanced internal architecture than the 90V series, allowing it to handle higher "inrush currents" from multiple large Air Conditioners starting simultaneously.
- Military-Grade Protection: It features a high-precision digital control motherboard that monitors power 24/7, shielding your sensitive electronics (OLED TVs, Servers, Inverter ACs) from spikes and fluctuations.
- 100% Copper Windings: Pure copper ensures that the unit can run at high loads for longer periods without the overheating issues common in aluminum-wound alternatives.
What Can This 20KVA Stabilizer Power?
A 20KVA central stabilizer is designed for a large 4-5 bedroom duplex or a medium office. It can comfortably manage:
- 4 to 5 Air Conditioners (Mix of 1.5HP and 2HP).
- 2 Large Double-Door Fridges + 2 Deep Freezers.
- 1HP or 1.5HP Water Pumping Machine.
- Entire Home/Office Lighting, Multiple Fans, and Laptops.
- Washing Machine, Microwave, and Dishwasher.
Maintenance & Installation Tips
- Wiring Gauge: You must use a minimum of 16mm or 25mm Pure Copper cables for the main input and output. Anything smaller will cause a significant fire hazard at 20KVA loads.
- Cooling: Ensure the unit is placed in a space with at least 50cm of clearance on all sides. The internal fans need to move air to keep the massive transformers cool.
- Breaker Protection: Install a high-quality 63A or 100A Change-over/MCB at the distribution point to handle the potential current throughput.
Would you like me to check for 25mm Pure Copper Cables to go with this unit, or do you need a 3-Phase 20KVA model if your building has a 3-phase connection?
