This manual describes the functions and features of the Delta PSC 3 controller, including the user interface, physical connections, and modules.
The Delta PSC 3 controller is a modular power system controller that can be used for small to large, complex power installations. It includes a central unit with basic I/O, a CAN‑based IMBUS communication bus, and optional external modules for monitoring and control. The integrated PLC and web server enable flexible monitoring, remote alarms, and configuration via Ethernet, modem, or LAN.
The manual covers the controller’s features, functional overview, user interfaces (web and local), physical connection options, and detailed descriptions of each module, such as the User Interface Module, String Sensor Module, and Fan Speed Controller. It also provides information on alarm levels, battery management functions, and AC measurement capabilities.
