Constant Voltage Transformers (CVTs), also known as ferroresonant transformers, are specialized electrical devices that provide a stable output voltage regardless of fluctuations in the input voltage. Here are some key features of Constant Voltage Transformers:

• Voltage Regulation: The primary function of CVTs is to regulate and stabilize the output voltage. They maintain a constant output voltage within a narrow tolerance range, even when the input voltage varies significantly.
• Ferroresonant Technology: CVTs operate based on the principles of ferroresonance, which involves the interaction between the transformer's magnetic core and a resonant capacitor circuit. This unique technology enables the CVT to maintain a nearly constant output voltage, irrespective of input voltage fluctuations.
• Robust and Reliable: CVTs are known for their robust construction and high reliability. They are designed to withstand harsh environmental conditions, voltage transients, and short-duration overloads, ensuring long-term performance and durability.
• Isolation and Voltage Conversion: Constant Voltage Transformers provide electrical isolation between the input and output, protecting sensitive equipment from electrical disturbances and ground loops. They also offer the ability to convert the input voltage to a different output voltage level, depending on the application requirements.
• Wide Input Voltage Range: CVTs can accept a wide range of input voltages, allowing them to function optimally in areas with voltage variations or unreliable power supply. They effectively compensate for voltage sags, surges, spikes, and frequency variations.
• Fast Response Time: Constant Voltage Transformers have a fast response time, typically in microseconds, to changes in input voltage. This ensures quick and efficient regulation, minimizing the impact of voltage fluctuations on connected equipment.
• Load and Line Regulation: CVTs exhibit excellent load and line regulation characteristics. Load regulation refers to the ability to maintain a stable output voltage under varying load conditions, while line regulation refers to the ability to compensate for input voltage fluctuations.
• High Efficiency: Constant Voltage Transformers are known for their high efficiency in voltage regulation. They are designed to minimize power losses during operation, ensuring energy-efficient performance and reducing electricity consumption.
• Noise and Transient Suppression: CVTs provide inherent noise and transient suppression, reducing electrical disturbances and ensuring a clean and stable output voltage. This feature makes them suitable for sensitive electronic equipment, such as computers, medical devices, and telecommunications systems.
• Overload and Short-Circuit Protection: CVTs incorporate overload and short-circuit protection mechanisms to safeguard the transformer and connected equipment. These protective features help prevent damage due to excessive current or fault conditions.
