1.Programmable Functions
- General Functions – allows setting of a set of voltage, frequency, time, and operating output parameters;
- Step-function feature – allows you to configure multiple sets (up to 30 sets) of step voltage, frequency, and duration; the system will then operate according to these configured steps; additionally, you can set the number of cycles and the cycle interval time.
- Gradient Function – Allows you to configure multiple sets (up to 30 sets) of start voltage frequency, stop voltage frequency, start time, and operating time; the system will then automatically perform an output operation with a VF variation according to these settings.
- VF Starting Kinetic Energy – For motor testing and high-power motor starting applications, it is possible to configure a fixed-frequency variable voltage followed by variable frequency variable voltage mode to reduce the inrush current during startup.
Special Curve Simulation – For complex pressure or frequency variations, the voltage-frequency curve can be configured within the system based on customer requirements or relevant test specifications.
2.Supports parallel redundancy functionality
- Supports dual or multi-machine parallel expansion to increase system capacity and improve power supply availability.
- Supports dual-machine redundant operation, thereby enhancing power supply reliability.
Supports independent or parallel expansion operation across two or more units (in standalone mode: each unit can independently set its frequency and voltage; in parallel operation mode):
3.Multi-purpose functionality
- Operates in standard three-phase output mode, providing a standard three-phase voltage with phase differences of 120° between each output phase;
- The device can also operate in single-phase mode; in this mode, the three single-phase output voltages, frequencies, and phases are identical. The three single-phase outputs can be connected in parallel externally to the power supply to function as a single-phase power source, achieving a threefold increase in single-phase load capacity compared to traditional power supplies. The switch between single-phase and three-phase modes can be performed with a single button press; no complex internal wiring adjustments are required. Additionally, the power supply is equipped with self-diagnostic and protection functions, effectively preventing output short circuits caused by erroneous switching between single-phase and three-phase modes.
- Three-phase separate control function: The frequency and output voltage of each individual phase can be adjusted independently; each of the three single-phase outputs can deliver different frequencies and voltages.
4.Three-phase phase angle adjustable function
- In the three-phase output mode, the phase angle of the three-phase output voltage can be adjusted; the adjustment range is 0–360°, with an adjustment resolution of 0.1°.
5. RS232/RS485 communication interface
- The system employs the MODBUS communication protocol. Users can achieve centralized control via a computer or PLC to set operating commands for the inverter power supply, modify or read functional parameters, and retrieve the inverter power supply’s operating status and fault information.
