Rated Voltage: For the inverter, the rated voltage mainly includes single-phase 220~240V and three-phase 220V or 380~460V. In China, the rated voltage of low-voltage inverters is mostly three-phase 380V13.
Rated Frequency: Typically set to 50Hz or 60Hz, with 50Hz being the standard in China13.
Output Voltage: The rated output voltage is defined as the maximum value in the output voltage range since it varies with frequency. It is often equal to the rated input voltage1.
Output Current: The rated output current refers to the maximum current that can be output continuously, which is the main basis for users to choose an inverter3.
Output Capacity: The rated output capacity is determined by the product of the rated output voltage and the rated output current3.
Protection Functions: Includes motor overheat protection, motor start monitoring, rotor stall, phase-to-phase overcurrent, undercurrent, negative sequence protection, zero-sequence current, and circuit breaker failure protection1.
Communication Interfaces: REF610 has two independent communication interfaces, RS-485 or fiber optic interface. Supports protocols such as MODBUS RTU/ASCII, IEC60870-5-103, DNP3.0, and SPA1.
Fault Recording: REF610 has an integrated fault recorder module with four analog input channels and up to eight user-selectable switch channels for complete fault status recording1.
Self-Diagnosis: The self-diagnosis function can determine the relay’s condition and issue warning signals before failure1.
