Specification parameters

Input characteristics

Rated input voltage: Supports multiple common high voltage specifications, such as common 3000V ± 15% and 6000V ± 15%. It can adapt to different power grid environments and equipment front-end input requirements, ensuring stable operation within a certain range of voltage fluctuations, and guaranteeing the stability and reliability of module operation.

Input power factor: ≥ 0.95. A higher power factor means that the module has a higher effective utilization rate of grid electricity, reduces the consumption of reactive power, lowers line losses and adverse effects on the grid, and helps improve the overall operational efficiency of the power system.

Output characteristics

Output frequency range: usually 0-50Hz, this frequency range can meet the needs of most industrial equipment for applications such as motor speed regulation. By flexibly adjusting the output frequency, precise control of connected devices can be achieved, such as controlling the speed of high-voltage motors, in order to regulate the production process and save energy.

Output frequency resolution: up to 0.01Hz, high resolution makes frequency adjustment more delicate. In scenarios where high precision is required for device operation, it can accurately control the device's operating status, ensuring the stability and consistency of device operation.

Rated output current: There are different current specifications based on different application scenarios and adapted device power. For example, in some applications where the motor power is small, the rated output current may be between 25-50A; while for devices such as high-power motors, it can reach different levels such as 300-720A to meet the current requirements of various loads.

Capacity adaptation

Variable frequency drive capacity (KVA): It has a wide capacity range, such as in 3kV series applications, the variable frequency drive capacity covers the range of 250-750KVA, 750-1500KVA, 1500-3000KVA, etc; In the 6kV series applications, the capacity of the frequency converter varies from 250-500KVA to 3000-7500KVA and other specifications. It can adapt to high-voltage equipment of different power levels to meet diverse industrial production needs.

Suitable motor power (KW): Corresponding to the capacity of the frequency converter, the suitable motor power for the 3kV series is 200-600KW, 600-1250KW, 1250-2500KW, etc; The 6kV series is suitable for motor power ranging from 200-400KW to 2500-6000KW. Flexible matching of high-voltage motors with different powers to achieve efficient speed regulation and control of the motor.

Control and protection characteristics

Control mode: Supports V/F control or magnetic field oriented closed-loop control. The V/F control method is simple and easy to use, suitable for general application scenarios where control accuracy requirements are not particularly high; Magnetic field oriented closed-loop control can achieve more precise motor control and perform well in situations where high requirements are placed on motor dynamic performance and control accuracy, such as high-performance industrial transmission systems.

Overload capacity: With an overload capacity of 150% (1 minute). When the device encounters impact loads or other situations in a short period of time, the module can withstand a certain proportion of current exceeding the rated load for 1 minute, ensuring that the device will not shut down due to short-term overload and enhancing the reliability and stability of system operation.

Protection function: equipped with comprehensive protection mechanisms, including overvoltage protection, overcurrent protection, overheating protection, etc. When the input voltage is too high, the output current is too high, or the internal temperature of the module is too high, protective measures should be taken quickly, such as cutting off the circuit, to prevent damage to the module and connected equipment due to abnormal conditions and ensure the safety of equipment and personnel.

Operating environment parameters

Operating temperature: The general operating environment temperature range is 0-40 ℃ (special requirements can be customized). Within this temperature range, the module is able to maintain good performance and stability. Exceeding this temperature range may affect the performance of electronic components inside the module, shorten their service life, and even cause malfunctions.

Environmental humidity: The environmental humidity requirement is less than 90%, with no condensation (special requirements can be customized). When the humidity is too high and condensation occurs, it may cause problems such as short circuits and corrosion in the internal circuits of the module, affecting the normal operation and reliability of the module.

Altitude: Suitable for altitudes<1500 meters (special requirements can be customized). As the altitude increases, the air becomes thinner, the heat dissipation conditions deteriorate, and the electrical insulation performance may decrease. The specified altitude range can ensure the reliable operation of the module under normal environmental conditions.

Heat dissipation and protection

Heat dissipation method: Adopt heat pipe air cooling or water cooling and other heat dissipation methods. Heat pipe air cooling utilizes the efficient thermal conductivity of heat pipes combined with air cooling for heat dissipation, with a relatively simple structure and easy maintenance; The water cooling method has higher heat dissipation efficiency and is suitable for applications with high heat generation and high heat dissipation requirements, ensuring that the heat generated by the module during operation can be dissipated in a timely manner and maintaining the normal working temperature of the module.

Protection level: The usual protection level is IP40. This protection level can prevent objects larger than 1.0mm from entering, prevent mosquitoes, flies, insects, or objects with a diameter larger than 1.0mm from entering the interior of the module, provide certain protection for the internal circuit of the module, and improve the reliability of the module in general industrial environments.

Core functions

Precise control: It can accurately regulate the operating parameters of high-voltage equipment, such as the speed and torque of high-voltage motors, to ensure that the equipment can maintain optimal operating conditions under different working conditions, and improve production efficiency and product quality.

Communication Interaction: Supports multiple communication protocols such as Modbus, Profibus, CAN, etc., facilitating data communication and interaction with other devices, enabling remote monitoring, diagnosis, and management, and facilitating centralized management and maintenance of equipment by operators.

Protection Monitoring: Equipped with comprehensive protection functions such as overvoltage, overcurrent, and overheating, it monitors the real-time operation status of equipment. In case of any abnormalities, protective measures are quickly taken, such as cutting off the circuit to prevent equipment damage and accidents, ensuring the safety of personnel and equipment.
