1. Fast Dynamic Response: Dual closed-loop feedback circuit, with the inner loop current loop ensuring non-linear load waveforms are not distorted; the outer loop voltage loop guarantees sudden load voltage drop <1%, with a response time less than 2mS.
2. User-friendly interface, source integration, and high measurement accuracy: High-power power supplies are equipped with 7-inch or 10-inch color touchscreens for display. The screens can show three-phase output voltage, current, power, frequency, and input DC bus voltage values. Parameters for local communication, such as local address and baud rate, can be set. The system can automatically record, store, and display events like power-on, power output start, stop, faults, and fault types, along with the date and time of occurrence. It also allows setting time intervals (1-60 seconds) for monitoring and recording power parameters, including date, time, three-phase voltage, and three-phase current. Users can review historical events and data records through the event log interface. Alarm Information Interface: When the inverter power supply system encounters a fault or operation error, the touch screen automatically pops up an alarm information interface, displaying the fault type and handling method. This inverter power supply utilizes DSP digital signal processing technology and features various fault detection capabilities, including overcurrent in internal IGBT devices, overvoltage and undervoltage in three-phase outputs, overcurrent and overloading in three-phase outputs, overvoltage and undervoltage in DC input, overheating of internal devices, synchronization signal faults, communication faults, and synchronization setting errors. These faults are directly displayed on the touch screen.

3. High Load Capacity: Power components are applied reasonably, capable of withstanding surges of over-rated current without causing voltage drop.
4. Superior Stability: Voltage stability ≤1%, load stability ≤1%. The output frequency is generated by a quartz oscillator, resulting in an extremely stable and accurate frequency. Other manufacturers cannot achieve this level of precision; their readings show as set values.
