● The entire system’s electrical control cabinet features an indoor Rittal-style design with an IP40 protection rating.
● The main power supply for the electrical control cabinet is a three-phase, five-wire system with a rated voltage of AC380V, a rated frequency of 50Hz, and a maximum load current of 200A.
● The black wire inside the cabinet is the AC380V power line, the yellow wire is the AC220V control line, the blue wire is the DC24V control line, and the yellow-green line is the ground line.
● The main components inside the cabinet include a molded case circuit breaker, a miniature circuit breaker, an intermediate relay, an AC contactor, and a frequency converter.
The ACS880 series inverters in the cabinet utilize the most advanced direct torque control (DTC) algorithm, precisely controlling every switching cycle of the power devices. Compared to vector and scalar control, this reduces unnecessary switching cycles and improves energy efficiency.
The cabinet features an advanced operator panel, which connects to the internal inverter and allows for start/stop control of the inverter and displays operating status information.
