INVERTER

Core technologies and product features:
Powerful sensorless vector control (low-speed, high torque) provides excellent dynamic response and overload capacity, delivering up to 200% high starting torque even at low speeds (e.g., 0.3Hz), ensuring smooth startup of heavy-load equipment. Exclusive micro-surge voltage suppression function (motor protection): Utilizing Hitachi's patented PWM pulse control technology, it effectively suppresses the motor terminal voltage to less than twice the DC voltage. This achieves motor insulation and protection, extending motor life, without the need for an additional output reactor. Excellent tripping suppression and stability: When equipment encounters sudden acceleration or deceleration, the inverter automatically detects and suppresses instantaneous surges in current and voltage, preventing overcurrent or overvoltage-induced shutdowns and significantly improving the continuous operation rate of the production line.
Extensive motor compatibility: In addition to traditional three-phase induction motors (IM), it widely supports driving high-efficiency permanent magnet synchronous motors (PM) and features a protection mechanism to prevent PM motor demagnetization, aligning with the green and energy-saving trends of modern factories. High environmental adaptability and long lifespan: The core circuit board is coated with varnish (insulating varnish) during the manufacturing process, improving durability in harsh, dusty, or humid industrial environments. Furthermore, the system incorporates lifespan diagnostics for capacitors and cooling fans, providing warnings and maintenance reminders before components age. High integration and rich communication interface standards: It includes an EMC noise filter and Modbus-RTU communication interface, and can be expanded to include various mainstream industrial networks such as Ethernet, EtherCAT, and PROFIBUS-DP, facilitating seamless integration with PLC or SCADA systems.
