Product Advantages
High-Efficiency IPM Technology
Utilizing the sixth-generation efficient IPM intelligent module from Mitsubishi, Japan, this converter ensures high efficiency and stable performance. Its robust protection mechanisms against short circuits, overload, and overheating guarantee safe and reliable operation, with a service life extending up to 15 years or more.
Flexible Start Modes
Offering two start modes — Reduction Voltage Start and Variable Frequency Start — users can customize based on load requirements. This reduces the need for additional frequency converters, lowering equipment investment costs and simplifying wiring and control procedures.
Pure Sine Wave Output
Delivers a pure sine wave output with excellent transient response (less than 50ms) and minimal waveform distortion. This results in higher conversion efficiency and stable output voltage, ensuring optimal performance for connected devices.
Electrical Isolation
By employing a low-frequency transformer, the converter achieves complete electrical isolation between input and output voltages, effectively preventing interference and ensuring a clean, reliable power supply.
SVPWM Space Vector Algorithm
Leveraging the SVPWM space vector algorithm, the converter achieves high conversion efficiency, high instantaneous power, and low no-load losses (exceeding 94% efficiency with minimal no-load loss). This enhances overall system performance and reduces energy waste.
