Product Features：
High-high direct high-voltage power supply: high-voltage variable frequency drive has high-voltage direct input and high-voltage direct output, without the need for output step-up transformers. The equipment occupies a small area and is suitable for ordinary AC induction motors;
High efficiency: The efficiency of high-voltage variable frequency drive can reach over 96%;
High power factor: The power factor of the high-voltage variable frequency drive can reach 0.95 or above;
No harmonic input: The high-voltage variable frequency drive uses phase-shifting multiple rectification technology for input, resulting in low voltage and current harmonics. There is no need to add harmonic control devices for input, which does not cause pollution to the power grid;
No harmonic output: The high-voltage variable frequency drive outputs standard sine wave current, with low voltage and current harmonics. The output does not require the addition of harmonic compensation devices, does not increase the operating noise of the motor, and does not generate additional stress;
High reliability: The high-voltage variable frequency drive has automatic fault bypass and high-voltage power outage restart functions, ensuring that the motor does not stop running in case of faults;
High safety: The design of the high-voltage variable frequency drive follows the mandatory high-voltage national regulations, and the optical fiber connection between the high-voltage main circuit and the control circuit is safe and reliable;
Complete protection and fault alarm design: The high-voltage variable frequency drive is equipped with complete system protection functions and power unit protection functions. After various protection actions, it can achieve automatic fault recording and accident memory. Fault recording can automatically record the types and times of various protection actions, helping technical personnel analyze the cause of faults and locate them;
High flexibility: The high-voltage variable frequency drive is controlled on-site through PLC, and the control mode can be flexibly changed by modifying parameter settings through the human-machine interface. It has multiple standard communication protocols to facilitate communication with the central control system;
Convenient installation, commissioning, and maintenance: The power unit is designed in the form of a drawer, and the power unit and external wiring are connected through connectors, without the need for manual wiring. It has good interchangeability and is easy to replace.
