The Rexroth Bosch MPN 1070086049 (PST6250.201-L) is a solid-state thyristor power unit engineered for supplying controlled power in metal resistance welding processes, including seam, spot, and projection welding. The unit interfaces with a welding transformer and features an integrated PROFIBUS weld timer for precise regulation of current and time. It operates with a nominal system current of 200 A, a maximum duty cycle of 50%, and requires a 24 V DC supply. Cooling is achieved using an air blower, and overvoltage protection is provided via metal-oxide varistors (MOVs). The device functions at ambient temperatures from 0 to 55°C and at altitudes up to 2000 meters, with a mass of approximately 13 kg. Installation is intended for gear cabinets or modular enclosures.
