Indramat PST6 Power Units

Indramat PST6

The PST 6000 thyristor power units are designed to control welding transformers, offering a range of integrated features and functionalities for enhanced performance and flexibility. They come with an integrated control system and a weld timer that is part of the central processing unit (CPU), ensuring precise management of welding operations. For adaptability in various setups, they provide flexible parallel and/or serial I/O interfaces, as well as optional fieldbus interfaces for communication, allowing for easier integration into different industrial environments. These power units also feature separate control and monitoring functions to ensure reliable and efficient operation. Additionally, the PST 6000 units offer slots for a type-specific I/O interface, a field bus module for programming, and a quality module, all of which are optional for customization based on the specific needs of the application. The units can be either air or water-cooled, depending on the requirements of the installation environment, ensuring they maintain optimal temperatures during operation.

Notable Features

The PST-6000 products boast a range of features designed for efficiency and optimization. They include integrated control functionality, ensuring streamlined operations. An integrated weld timer contributes to precise process timing, while flexible parallel and/or serial I/O interfaces offer versatile connectivity options. For communication, the system provides fieldbus interfaces. There are dedicated integrated control and monitoring functions, with the control functionality being separate from monitoring for clarity and efficiency. The products can be either air or water cooled, depending on the requirements, and their design necessitates less cabling due to the integration of system components. They are also geared towards quality with functionality designed for welding quality optimization. The system can be easily integrated into a portable welding box system (SCHWEISSKOFFER), enhancing its portability and convenience. Lastly, the BOS-5000 operator interface facilitates easy programming, operation, and diagnostics, making the user experience as smooth and straightforward as possible.
