The Bosch Rexroth R911309354 (PST6250.627-L) is a top-quality, 2-phase thyristor power unit utilized for welding transformer connections. Featuring an integrated weld timer and an optional quality module slot, the R911309354 (PST6250.627-L) ensures a high degree of efficiency and flexibility. With an IP20 level of protection, it requires an IP54 class environment to operate efficiently. The device should be kept away from acids, corrosive substances, salts, and other harmful materials. It can function up to 2000 meters elevation and within a humidity range of 90%(at 20°C) to 50% (at 40°C). It operates efficiently at temperatures varying from -25°C to 55°C. Equipped with an overload-protection metal oxide varistor, it handles a nominal system current of 200A, a line voltage of 400V-600V, and functions at a clock frequency of 50/60Hz. While its weight is around 12.5kg, it accommodates a wire range of 95mm2. Additionally, this power unit's mounting options include left side and rear panel, and it has specific spots for mains supply and welding transformer connections. If the operating temperature exceeds 80°C, a thermostatic switch will inhibit additional activities to avoid overload. The product includes a one-year warranty.
