The Bosch Rexroth R911309354 (MPN: PST6250.627-L) is a 2-phase thyristor power unit designed for welding transformer connections, with an integrated weld timer and an optional slot for a quality module. The device has a nominal system current of 200 A, operates on a line voltage of 400–600 V at 50/60 Hz, and includes a 24 V DC voltage supply. Cooling is facilitated by an air blower. The unit is rated at IP20, requiring installation in an IP54-class environment. It can be mounted on the left side or rear panel, supports up to 95 mm² wire, and weighs 12.5 kg. Functional limits include elevations up to 2000 m, 90% humidity at 20°C (down to 50% at 40°C), and an ambient operating range of -25°C to 55°C. Overload protection is provided by a metal oxide varistor, and thermal inhibition is triggered above 80°C via thermostatic switch.
