PST610-EL

The Bosch Rexroth Indramat PST610-EL from the PST Thyristor Power Units series offers a robust solution for industrial welding applications, featuring a nominal system current of 130 A and a voltage supply of 24 V DC that ensures stable power delivery. This solid-state, semiconductor-based unit employs an Air Blower cooling method for optimal thermal management and integrates an integrated timer to streamline welding cycle control. Designed for resistance welding of metals, the PST610-EL delivers persistent current characteristics that adapt automatically to load demands. Its compact, portable design simplifies installation and minimizes cabling in high-density manufacturing environments.

Engineered for versatility, the PST610-EL supports a rated input voltage of 400 V -20% to 600 V +10% at 50/60 Hz, delivering up to 76 kVA of total output power. Safety features include overvoltage, over-current, and overload protection, while a built-in thermostat triggers a thermal trip at 80 °C to safeguard against overheating. The drive’s IP54 protection class metallic enclosure resists dust and water ingress, meeting stringent industrial EMC standards (DIN EN 50082-2, EN 50081-2). Additionally, versatile communication is provided via parallel and serial I/O interfaces, a Fieldbus communications interface, and the dedicated BOS-5000 programming and diagnostics interface.

With its durable construction and integrated battery compartment, the PST610-EL is tailor-made for demanding shop-floor environments. Bosch Rexroth Indramat backs each unit with a one-year warranty, ensuring reliable performance and support from initial commissioning through long-term operation. The result is a high-precision, low-maintenance thyristor power controller that excels in heavy-duty industrial welding applications.
