Constant Voltage Transformer
A Constant Voltage Transformer (CVT) is a specialized transformer designed to provide a stable output voltage regardless of input voltage fluctuations. It is widely used in industries and sensitive electronic applications where voltage stability is critical. Unlike conventional transformers, a CVT maintains nearly constant voltage by utilizing a ferroresonant circuit, which combines magnetic saturation and resonance to regulate the output automatically.
CVTs are particularly effective in protecting sensitive equipment such as computers, medical devices, laboratory instruments, and communication systems from voltage spikes, sags, and surges. They can handle input voltage variations typically ranging from ±20% to ±30% while delivering a steady output voltage, ensuring uninterrupted and reliable operation of connected devices.
Another key advantage of CVTs is their ability to filter electrical noise, harmonics, and transients, improving the overall power quality. They are rugged, low-maintenance, and capable of continuous operation under harsh conditions, making them suitable for industrial environments.
In addition to voltage regulation, CVTs also provide isolation from the input power source, enhancing safety for both equipment and operators. Overall, Constant Voltage Transformers are indispensable in scenarios where maintaining precise voltage levels is crucial, combining protection, stability, and reliability in a compact and efficient electrical solution.
