The Bosch Rexroth MPN R911335602 (PST625E.101-L) is a two-phase AC welding controller for resistance welding applications. It provides a 141 kVA power rating at a 50% duty cycle, with operation supported within air temperatures from 0 to 55 °C and a maximum cooling air temperature of 45 °C. The device incorporates air blower cooling, an integrated weld timer, and a nominal system current of 200 A. Electrical connections are made via terminals rated for 15-18 Nm tightening torque and up to 95 mm² core area. Overvoltage protection is provided by a metal-oxide varistor. The controller operates at supply voltages of 24 V DC and in altitudes up to 2000 meters. Operating weight is approximately 12 kg. Installation should be in environments free of corrosive agents, heavy acids, metal vapors, or salts, with proper adherence to industrial safety standards.
