The Bosch Rexroth 1070081793 (PST6250.321-L) is a two-phase thyristor power unit with integrated control capabilities, ideal for welding applications. This compact unit significantly reduces cable needs due to its built-in functions including a weld timer, I/O interface, quality control module and control and monitoring capabilities. It operates under an air pressure that's within 2000m above sea level and weighs 12.5kg, only permitting vertical or back facing mounting plate positions. The model boasts a nominal system current of 200A and a power supply voltage ranging from 19 V DC to 24 V DC. With an integrated Metal Oxide Varistor, the unit safeguards against overvoltage alongside its overloading alert system. It permits a maximum duty cycle of 50%, regardless of its operating current, the monitor of which is maintained by the integrated de-excitation resistor. Please note, this unit is designated strictly for welding transformer connections, with other uses potentially causing unit damage or user harm. It carries an IP20 protection rating and a one-year warranty, available for global shipping through Indramat USA.
