PST6250.201-W

The Bosch Rexroth Indramat PST6250.201-W from the PST Thyristor Power Units series is a high-performance thyristor power unit designed for heavy-duty welding applications. This model delivers a Nominal System Current of 200 A and operates from a 24 V DC Voltage Supply, while its Integrated Timer function enables precise process control. To maintain stable operation, the unit employs an Air Blower cooling system, ensuring reliable heat dissipation in continuous industrial use. With its compact footprint and rugged construction, the PST6250.201-W integrates seamlessly into modern welding equipment.

Engineered exclusively for welding transformer connections, the PST6250.201-W supports transformer ratings up to 250 kVA and handles a continuous thermal rated current of 200 A without derating. The unit accepts a rated voltage range of 400–600 V, and features built-in temperature monitoring to prevent overheating. Installation is simplified by its recommended vertical mounting position or rear-plate attachment, and users should consult the load diagram to calculate permissible loads and avoid overloading. Rugged internal circuitry and safety interlocks maximize uptime in harsh factory environments.

Safety and integration are central to the design: the PST6250.201-W includes a pacemaker warning to restrict use around sensitive medical devices and incorporates system component integration that minimizes external cabling. Weighing approximately 12.5 kg, it can be mounted within portable welding boxes or fixed assemblies with minimal footprint impact. Supplied with a one-year warranty from Rexroth Indramat Bosch, this power unit offers a turnkey solution for demanding welding operations.
