PST6100.100-L

PST6100.100-L, Bosch Rexroth Indramat, PST Thyristor Power Units opens the line of advanced thyristor power modules designed for high-performance resistance welding applications. This PST6100.100-L unit integrates seamless 24 V DC Voltage Supply with a 130 A Nominal System Current, ensuring stable power delivery to welding transformers. The device features an Air Blower cooling scheme and an Integrated Timer for precise weld cycle management. Built to meet industrial standards, it delivers reliable performance in harsh factory environments.

The module’s technical foundation comprises a Rated Voltage: 400–600 V, a Rated Current: 110 A, and compatibility with transformers up to 76 kVA. An Integrated Thermostatic Switch blocks operations above 80 °C to protect the power electronics. Conformal-coated boards and DIN EN 50082-2/50081-2 compliance ensure electromagnetic immunity and emissions control. A slot for an I/O Interface and modular Fieldbus Interface permit flexible integration into automated welding lines. Continuous monitoring functions track temperature, current, and voltage in real time, while built-in control logic optimizes weld quality.

Installation benefits include tool-free access to the cooling blower and thyristor carriage, simplifying maintenance. With native compatibility across Bosch Rexroth Indramat networks, the PST6100.100-L can be paired with higher-level controllers for synchronized multi-gun welding operations. Its rugged design, redundant protection circuits, and industry-proven reliability minimize downtime and extend service intervals in high-duty industrial welding applications.
