PST6100.142-L

PST6100.142-L, Bosch Rexroth Indramat, PST Thyristor Power Units embodies a high-performance thyristor power stage engineered to regulate industrial welding currents with exceptional precision and repeatability. This unit controls nominal currents up to 130 A through fast switching thyristors, interfacing directly with a 24 V DC auxiliary supply for consistent drive performance. An Integrated timer function permits precise pulse shaping and dwell control in spot, projection, and seam welding processes, optimizing heat input and weld quality. Active air-blower cooling ensures stable thermal management under continuous or intermittent duty cycles, reducing thermal stress on power components.

It incorporates an advanced cooling assembly featuring a high-efficiency Air Blower that maintains optimal junction temperatures during peak duty operation. The robust enclosure meets IP20 protection category requirements and adheres to Humidity Class F specifications, safeguarding internal circuits against dust ingress and moisture. Conformance to DIN EN 50082-2 and DIN EN 50081-2 electromagnetic compatibility standards assures immunity to external interference and limits radiated emissions, protecting nearby sensitive electronics. At a compact weight of 12.5 kg, the module fits standard drive racks, while its intuitive B00-5000 programming interface and multicolor LED indicator facilitate rapid commissioning and real-time diagnostics.

System integrators benefit from seamless incorporation of the PST6100.142-L into existing Rexroth Indramat control architectures, using standard bus interfaces and modular cabinet layouts. Its sturdy construction and reliable thermal regulation deliver consistent performance over extended production runs, minimizing maintenance intervals and unplanned downtime. Tailored for heavy-duty metal welding lines, robotic welding cells, and automated fabrication environments, the unit combines precise current modulation with long-term operational stability.
