1. Programmable Functions A. General Function - Set a group of voltage, frequency, time, and operation outputs. B. Step Function - Set multiple groups (over 30) of step voltage, frequency, and time, operating according to the set step output. It allows for setting the number of cycles and cycle interval time. C. Gradual Function - Set multiple groups (over 30) of start voltage frequency, end voltage frequency, start time, and operation time. The system automatically runs VF changes according to the set parameters. D. VF Start Dynamics - For motor testing and high-power motor startup, it allows setting a method of frequency change after a fixed-frequency voltage change to reduce the shock current during startup. E. Special Curve Mimic - For complex pressure and frequency changes, curves can be固化 in the system as per customer requirements or related test specifications, visible in the voltage-frequency curve.
2. Parallel Redundancy Function A. Expand capacity with dual or multiple machines in parallel operation. Enhance power supply availability. B. Operate in dual machine redundancy. Improve power supply reliability. C. Operate independently or in parallel expansion with dual or multiple machines (in independent operation: set frequency and voltage for single machine. In parallel operation)
3. Multi-functional Machine A. Operates in a standard three-phase output mode, producing a three-phase voltage with a phase difference of 120°. B. Also operates in single-phase mode, where the three single-phase output voltages, frequencies, and phases are identical. They can be directly paralleled outside the power supply to serve as a single-phase power source, offering three times the single-phase load capacity of traditional power supplies. C. Single-phase control function: Each single-phase output frequency and voltage can be independently adjusted, allowing for different frequencies and voltages to be output from the three single phases.

4. Three-Phase Phase Angle Adjustability: In three-phase output mode, the phase angle of the three-phase output voltage can be adjusted, with a range of 0-360° and a resolution of 0.1°.
5. The RS232/RS485 communication interfaces utilize the MODBUS communication protocol. Users can achieve centralized control via computers or PLCs, set inverter power supply operation commands, modify or read functional parameters, and retrieve inverter power supply's operating status and fault information, among others.
