Functional Features: Provides 376 W of stable output power sufficient for a fully populated AutoMax rack. Built-in overvoltage and overcurrent protection safeguards connected modules. Wide input voltage range (100–132 VAC) tolerates grid fluctuations. Aluminum housing with dedicated heat dissipation design improves interference resistance and durability.
Application Scenarios: Used in metallurgy, paper manufacturing, film production lines, and other industrial environments requiring high-reliability power for PLC, DCS, and servo drive systems.
Installation & Notes: Mounts into 3 slots of the AutoMax rack. Ensure input voltage is within 100–132 VAC range. The FAULT LED illuminates when an abnormal condition is detected; power should be disconnected before servicing.
