The Bosch 1070088333 (PST6250.346-L), part of the renowned PST 6250 series, is a robust thyristor power supply primed with a built-in weld timer and allotted with three slots for additional I/O and communication modules. Its welding operation necessitates a 24 Volts DC power output and is engineered to accommodate a 50% duty cycle independent of the working current. The device's duty cycle ceiling is enforced by a built-in 2.2 kilo-ohms de-excitation resistor. Additionally, the 1070088333 (PST6250.346-L) can work in tandem with welding transformers possessing a peak power rating of 250kVA. Crafted for convection cooling, optimum operation requires an unobstructed airflow clearance of 100mm and an operational temperature of up to 45°C. It requires an AC input of 400 to 600 volts and has a continuous thermal current deliverability of up to 200 Amps. Moreover, manufacturing allows global shipping with a full one-year warranty offered by Indramat USA.
