The A&E 30KVA Single Phase Servo Voltage Stabilizer (AESB13V-D-30KVA) is a high-performance, industrial-grade central power regulator. Unlike the "Extreme" low-voltage models (like the 45V or 80V series), the AESB130 is the standard "Wide Range" workhorse, specifically designed for large buildings where the voltage typically fluctuates between 130V and 260V.
Available at Kara.com.ng, this unit provides a rock-steady 220V ±3% output, making it the preferred choice for protecting high-end sensitive equipment that cannot tolerate the "voltage steps" of relay stabilizers.

The AESB130-D is a significant investment in building-wide protection. While it is more expensive than relay units, its precision and durability for inductive loads (like multiple ACs) justify the cost.
| Model Variant | Input Range | Estimated Price (2026) |
| AESB130-D-30KVA (Standard) | 130V – 260V | ₦1,437,500 – ₦1,488,000 |
| AESB80-D-30KVA (Wide) | 80V – 260V | ₦1,850,000 – ₦1,980,000 |
| A&E 30KVA Relay Model | 45V – 270V | ₦1,050,000 – ₦1,250,000 |
Selection Tip: If your power is generally "decent" (fans spin well, but ACs struggle to kick in), this 130V model is perfect. If your area suffers from "dead" light (bulbs barely glowing), you must upgrade to the 80V Servo or the 45V Relay version.

Why Choose the 30KVA Servo Over a Relay Model?
- Zero Flicker: Relay stabilizers "click" and jump in 10V–20V steps. The servo motor moves smoothly across the transformer windings, providing a seamless flow of power that is much safer for OLED TVs, Servers, and Medical equipment.
- Inverter AC Protection: Modern Inverter Air Conditioners use delicate motherboards. The precision of a servo stabilizer prevents the minor surges that occur during relay switching from shortening the lifespan of your AC's electronics.
- High Efficiency: With an efficiency rating of over 97%, this unit wastes very little power as heat, which is vital for reducing your electricity bills and extending the unit's lifespan.
- Centralized Control: A single 30KVA unit can be wired directly to your main change-over switch to protect every single socket and bulb in a massive duplex or medium-sized office.
What Can This 30KVA Stabilizer Power?
A 30KVA central unit is a powerhouse. In a typical luxury home or office, it supports:
- 6 to 8 Air Conditioners (Mix of 1.5HP, 2HP, and one 3HP).
- Multiple Large Double-Door Fridges + 3 Chest Freezers.
- 1.5HP or 2HP Water Pumping Machine.
- Entire Building Lighting, Smart TVs, Sound Systems, and CCTV.
- Large Kitchen Appliances: Microwave, Electric Oven, and Dishwasher.
Maintenance & Installation Tips
- Wiring: For 30KVA on a single-phase line, you must use a minimum of 25mm or 35mm Pure Copper cables. Using 10mm or 16mm wires will lead to excessive heat and potential fire hazards at the input terminals.
- Ventilation: This is a floor-standing unit on wheels. Ensure it has at least 50cm of clearance on all sides. It generates heat while correcting low voltage and needs the airflow to keep the massive transformers cool.
- Annual Service: Since this unit uses a moving carbon brush, have a technician open the cabinet once a year to blow out dust and check the brush wear.
