1. Programmable Features A. General Function——Set a group of voltage, frequency, time, and operating output. B. Step Function——Set multiple groups (up to 30 groups) of step voltage, frequency, and time, operating output according to the set steps. The cycle count and cycle interval time can be set. C. Gradual Function——Set multiple groups (up to 30 groups) of starting voltage/frequency, ending voltage/frequency, starting time, and operating time. The system automatically performs VF change operation output according to the settings. D. VF Start Energy——For motor testing and high-power motor start-up, it can set a method of frequency changing after fixed frequency voltage change, reducing the impact current during start-up. E. Special Curve Imitation——For complex pressure and frequency changes, the system can be solidified according to customer requirements or relevant test specifications, converting voltage/frequency curves.
2. Parallel Redundancy Function A. Expand capacity through dual or multi-machine parallel operation. B. Dual-machine redundancy for enhanced power reliability. C. Independent and parallel expansion operation with dual or multi-machine (in independent operation: single machine can set frequency and voltage freely. In parallel operation) Avionics Ground Power 2, 36V Avionics Power 1, 400HZ Frequency Converter Power 7, 115/200V Power 2, 27V DC Power 5, 400HZ Power 12, Avionics Power
3. Multi-functional Machine A. Operates in a standard three-phase output mode, producing standard three-phase voltages 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 source to function as a single-phase power supply, offering triple the single-phase load capacity of traditional power sources. C. Single-phase control function: The frequencies and voltages of the three single-phase outputs can be independently adjusted, allowing for different frequencies and voltages to be output from each single phase.
4. Tri-phase Phase Angle Adjustable Function: In the tri-phase output mode, the phase angle of the tri-phase output voltage can be adjusted, with a range of 0-360° and an adjustment resolution of 0.1°.
5. The RS232/RS485 communication interfaces utilize the MODBUS communication protocol. Users can achieve centralized control via a computer or PLC, set inverter power supply operation commands, modify or read functional parameters, and access the inverter power supply's working status and fault information, etc.
