2. Technical features
‌Core functions‌
‌AC/DC conversion‌: three-phase AC is rectified into DC through a diode module, and then converted into adjustable AC by IGBT after capacitor filtering, supporting high-precision motor speed regulation ‌.
‌Modular design‌: supports quick replacement, integrated unit power board (24V DC output), control board (signal processing and fault monitoring) and driver board (IGBT control).

‌Intelligent control and protection‌

‌Real-time monitoring‌: The unit control board detects overcurrent, overheating, overload and other faults in real time, and reports to the main control system through the optical fiber interface ‌.
‌Multiple protection‌: Built-in lightning protection (4000V), surge absorption (600W) and overcurrent protection (1.5A) to ensure safe operation of the equipment ‌.

‌Communication and expansion‌

‌Rich interfaces‌: Equipped with optical fiber interface, power interface and drive signal interface, supporting Profibus DP, Profinet and other protocols, easy to integrate industrial automation network ‌.
‌Remote monitoring‌: Support Ethernet and RS485 communication to achieve remote parameter adjustment and status monitoring ‌.

3. Application areas ‌

High-power industrial drive‌: Suitable for variable frequency speed control of equipment such as fans, pumps, compressors, etc. ‌.
‌Energy management‌: Used in power generation, power transmission and distribution, water treatment and other scenarios to optimize energy consumption and reduce harmonic losses ‌.
‌Heavy machinery‌: mining, metallurgical production, chemical equipment and other high-load, high-reliability demand scenarios ‌.

4. Product advantages ‌

High efficiency and energy saving‌: Adopting IGBT inverter technology and optimized control algorithm, the energy conversion efficiency is improved by 15-20% ‌.
‌Stable and durable‌: Industrial-grade component design, mechanical and electrical life of 20 years, adaptable to harsh environments ‌.
‌Easy maintenance‌: Modular structure supports quick replacement and reduces downtime; built-in self-diagnosis function simplifies troubleshooting ‌.

5. Precautions ‌

Installation requirements‌: Ensure sufficient heat dissipation space to avoid high temperature and dust environment; input voltage must strictly match the specifications ‌.
‌Maintenance recommendations‌: Regularly check the fiber link, capacitor status and IGBT module, and it is recommended to perform preventive maintenance every quarter ‌.
‌Compatibility verification‌: When replacing spare parts, it is necessary to confirm that the communication protocol and interface match the original high-voltage inverter system.
