Product Description
The PST625-EL by Bosch Rexroth is an AC welding controller. The PST 625 series has an integrated control function and features an air-cooling mechanism. The PST625-EL finds application with stationary welding equipment and other industrial use cases up to 141 kVA. Generally, the rated voltage range of the PST 625 welding controller series is 400 – 600 V (-20 % to 10 %) and an operating clock frequency of 50 – 60 Hz. This series comes with an optional I/O interface for Fieldbus, serial or parallel connections. With a fan hood, its output current has a maximum value of 365 Amperes at 30 % duty cycle.
When mounted in a modular enclosure, its protection class is IP 20, but in switchgear cabinets, its protection class is IP 54. The maximum permissible ambient temperature of the PST625-EL is 55 degrees Celsius. Also, its maximum cooling air temperature is 45 degrees Celsius. At 20 degrees Celsius, the relative humidity of this equipment is 90 %, and at 50 degrees Celsius, its relative humidity is 50 %. During operation, storage and transportation, moisture condensation must be completely avoided.
The air pressure rating of the PST625-EL is acceptable for any value within 0 – 2000 meters above sea level. The nominal voltage supply of this equipment is DC 24 Volts. For corrosion protection, them ambient air or cooling air of the PST625-EL must be free of salts, caustic soda, acids, corrosive agents and metal vapours of varying concentrations. This welding controller must only be utilized for the intended applications as described by the manufacturer to prevent personnel injury, potential health hazards, damage to the equipment or the environment. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
