The A&E 10KVA Relay Voltage Stabilizer (45V-270V), often identified by the product code AERB45-W-15KVA, is an "Extreme Wide Input" power solution. While the name in some listings might lead with "10KVA," the AERB45-W-15KVA model is a 15,000VA (15KVA) unit specifically designed to thrive in areas where the national grid voltage is so weak that bulbs barely glow.
Available at Kara.com.ng, this series is the ultimate choice for a "Central Stabilizer" in large apartments or office complexes located in low-voltage zones.
A&E 15KVA Relay 45V-270V Price in Nigeria (2026 Update)
Prices for the AERB45-W series reflect the massive copper windings required to boost power from as low as 45V. In 2026, the 15KVA variant is priced as a premium industrial-residential hybrid.
| Model Variant | Capacity | Estimated Price (2026) |
| AERB45-W-15KVA | 15,000VA | ₦480,000 – ₦570,000 |
| AERB45-W-10KVA | 10,000VA | ₦385,000 – ₦435,000 |
| A&E 15KVA Servo (90V) | 15,000VA | ₦850,000 – ₦980,000 |
Selection Tip: The "45V" rating is a lifesaver. While standard stabilizers trip off at 90V, this unit keeps working. If you live in an area where your fans barely turn and you need to power an entire house, this is the specific series you need.
Key Specifications (AERB45-W-15KVA)
- Capacity: 15,000VA (15KVA) / Approx. 12,000W – 13,500W Max Load.
- Input Voltage Range: 45V – 280V AC (Extreme Wide Range).
- Output Voltage: 220V ± 10%.
- Technology: High-Speed Relay Switching (Instant Response).
- Transformer: 100% Pure Copper Toroidal Transformer.
- Display: Digital LED showing Input/Output Voltage and Load Level.
- Protection: Over-voltage (246V±4V), Under-voltage, Overload, High-Temperature, and Short-Circuit protection.
- Mounting: Wall-Mounted (Space-saving and secure).
Why the "45V" Rating is Critical
- Lowest Recovery in Nigeria: In many suburban areas, voltage drops to "dim light" levels (50V–70V). This stabilizer can pull that near-dead power and boost it to 220V, whereas most other brands will simply shut down to "Protect" themselves.
- Instantaneous Response: Unlike Servo motors that take a second to move their mechanical arms, Relays switch electronically in milliseconds. This provides superior protection against the sudden "jumps" in voltage that happen when the grid is unstable.
- Centralized Protection: At 15KVA, this unit is powerful enough to be installed at your main Distribution Board (DB). It acts as a shield for every single socket, bulb, and appliance in a large 3 or 4-bedroom home.
- Quiet & Cool: The AERB45 series features an Intelligent Auto Cooling Fan that only activates when the unit gets hot, ensuring it stays quiet during normal operation.
What Can a 15KVA Relay Stabilizer Power?
A 15KVA unit is a heavy-duty central solution. It can typically support:
- Three 1.5HP Air Conditioners (or two 2HP + one 1HP).
- Large Double-Door Refrigerator + Chest Freezer.
- Pumping Machine (1HP to 1.5HP).
- Washing Machine, Microwave, and Electric Kettle.
- Entire Home Lighting (LED), Multiple Smart TVs, and Sound Systems.
Maintenance & Installation Tips
- Cable Recommendation: For a 15KVA load, you must use a minimum of 16mm Pure Copper cables. Using 10mm or aluminum cables can cause the wires to melt or the stabilizer terminals to burn out due to the high current.
- Mounting Height: Install at eye level on a solid concrete wall. This allows you to monitor the digital display and keeps the unit away from floor-level dust and moisture.
- The "Clicking" Sound: It is normal to hear a "click" when the voltage fluctuates. This is the relay switching taps to maintain your power. Do not install it directly inside a bedroom if you are sensitive to noise.
Would you like me to verify the availability of 16mm Installation Cables for this unit, or do you need to compare this with the 20KVA Relay model for a larger building?
