PST6250.610-L

PST6250.610-L, Bosch Rexroth Indramat, PST Thyristor Power Units Drive Controller delivers a robust solution for high-current welding applications. This module integrates a semiconductor-based thyristor rectifier and a fast microprocessor, ensuring precise control over the welding arc. Featuring an embedded user interface, operators can adjust parameters directly without external tools. Its compact metal housing supports field-bus and I/O modules for seamless connectivity.

The unit accepts a Voltage Supply of 24 V DC alongside a primary Input Voltage Range of 400-600 V AC at 50/60 Hz, delivering a Nominal System Current of 200 A with integrated Overload Protection through a thermostatic switch. An onboard Timer is Integrated for automatic sequencing, while the Cooling is handled by a dedicated Air Blower to maintain thermal stability. Additional features include a dedicated I/O Interface Slot for type-specific modules and a provision for an optional fieldbus programming module. All control electronics are conformally coated and housed within an IP20-class enclosure for added durability.

Designed for seamless integration into industrial environments, the PST6250.610-L offers hot-swap slots for I/O, fieldbus, and quality-monitoring modules without altering the footprint. Its built-in overload detection halts operation at fault, preventing damage and reducing downtime. Fully compliant with EU machine directives and backed by a one-year warranty, this drive controller ensures reliable, continuous operation across global installations.
