series
The SPAU140C belongs to a family of ABB, but the specific family name is not explicitly mentioned.
trait
Function: With synchronization check function and voltage check function.
Operation mode: Support continuous automatic diagnosis and self-monitoring.
Communication function: With communication module, support HDMI interface.
Redundancy function: SPAU 140 c-aa product has dual optical ports to achieve redundancy of dual fiber ring network, which can ensure normal system communication.
High power density: The design of high power density reduces the overall size and weight of the motor.
System environment: The system environment is normal and the system capability is strong.

effect
Synchronization check: When two separate networks or two electrically interconnected network parts are to be connected together, the synchronization check function is used.
Voltage check: The voltage check function is used when the disconnected bus/line is to be connected to the energized part of the grid.
Protection Network: Provides protection when connecting individual components to a powered network.
Industrial automation: As an important part of industrial automation, it is widely used in CNC machinery, metallurgy, petroleum and natural gas, petrochemical, chemical, paper printing, textile printing and dyeing, machinery, electronic manufacturing, automobile manufacturing, electric power, water conservancy, water treatment/environmental protection, municipal engineering, boiler heating, energy, transmission and distribution and other fields.
