The R911170116 (PST6250.280-L) is a thyristor power unit from the PST 6250 series manufactured by Bosch Rexroth, engineered for integration with welding transformers in industrial settings. The unit is compliant with DIN EN 50082-2 and 50081-2 standards and features an integrated CPU weld timer, an I/O interface slot for serial, parallel, or fieldbus connections, and two optional slots for a fieldbus module and quality module. It is rated for IP20 protection against dust and intrusions, with improved IP54 protection when installed in a switchgear cabinet or modular enclosure. The system utilizes an air blower for cooling, supports a nominal system current of 200 A, and operates from a 24 V DC voltage supply. Humidity class F prevents condensation, and the unit is equipped with temperature monitoring to ensure reliable operation within its specified thermal range.
