The Rexroth R911171072 (PST650-EW) is a compact, high-performing 800 Amps weld controller, weighing approximately 11kg. It possesses an integrated, two-phase thyristor power supply unit with protective non-linear metal-oxide varistors (MOVs) to guard against overvoltages. The unit carries a voltage rating between 400 and 600 volts, with a frequency of 50/60 Hertz. It maintains a water-cooled heat loss system with a minimum flow quantity of 10 litres per minute and a maximum pressure differential of 0.9 bar. The device's nominal current has a maximum value of 800 A with a high output current of 2500 A and a 10% duty cycle. This 565 kVA weld controller features terminal connections with a tightening torque of 41-46 Nm and a cross-sectional area of 240 mm2. Maintenance should be undertaken by certified personnel, with component checks every six months and biennial battery replacements. Accompanied by a one-year warranty, it ships globally from Indramat USA.
