General Overview
The TVR 33 Series is a full automatic voltage regulator designed for non-linear charges with a three-phase input and output. It offers a wide power and voltage range, ensuring high reliability through the use of a microprocessor and smart driver. The system is characterized by fast regulation, high efficiency, and safe, economical usage. It includes features such as load transfer to bypass via a pole charge switch and overcurrent and overload protection. The status, input, and output measurements are digitally displayed.

General Specifications
The TVR 33 Series covers a power range from 200 to 3000 kVA. It operates with an input voltage correction interval of 285 - 440 VAC, with an optional range of 190-415 VAC, and a frequency range of 47 to 65 Hz. The system includes line input protection against overcurrent and voltage fluctuations.

Technical Specifications

• Input: The current at input varies from 323 to 4848 A depending on the model.
• Output: The output voltage is maintained at 380/400/415 VAC RMS with a tolerance of ±1%. It can handle overloading for 10 seconds at 200% load, with a correction speed of approximately 90 Volt/Sec.
• Protection: The system protects the load by opening the circuit in case of overburden or short circuit.
• Efficiency: The total efficiency is greater than 97%.

Environmental and Mechanical Specifications
The system operates within a temperature range of -10°C to 50°C and can be stored between -25°C and +60°C. It functions effectively at altitudes below 2000 meters and maintains an acoustic level below 55 dB. The protection level is rated at IP 20, and it complies with CE and ISO 9001 standards.
