PST6250.355-L

The Bosch Rexroth Indramat PST6250.355-L from the PST Thyristor Power Units series is a solid-state Thyristor-based transformer rectifier unit providing constant current characteristics for resistance welding. It features a Nominal System Current of 200 A, operates on 24 V DC supply voltage, and incorporates an Integrated timer. Rugged electronics and compliance with DIN EN 50082-2 and 50081-2 ensure EMC performance, while Air Blower cooling maintains thermal stability. The compact sheet-metal housing includes integrated control functionality, parallel/serial I/O and Fieldbus interfaces, plus a BOS-5000 operator interface for programming and diagnostics. A thermostatic sensor and MOV protect against over-temperature and over-voltage, and Protection Class IP20/IP54 design allows flexible industrial integration.
