The Century 5000VA (5KVA) Automatic Voltage Stabilizer (often designated as CVR-TUB 5000VA) is a heavy-duty, high-capacity voltage regulator designed to protect high-power appliances from voltage fluctuations, surges, and drops. It is particularly known for using 100% copper wiring, which provides better durability, heat resistance, and efficiency compared to models with aluminum, especially under high-load conditions like those in Nigeria.
