PST6250.280-L

Product Description

The PST6250.280-L is one of the thyristor power units with integrated control function in the PST 6250 series. It is manufactured by Bosch Rexroth for industrial environments as per DIN EN 50082-2 and 50081-2 on electromagnetic compatibility, specifically in connecting welding transformers. The PST6250.280-L is a fully integrated unit made up of components like a weld timer which is the central processing unit and a slot for the I/O interface, which in this case is serial, parallel or fieldbus. There is also an optional slot for the fieldbus module for programming and another optional one for retrofitting a quality module.

This two-phase thyristor power unit was module designed for recessed mounting, and can only be installed in a particular ambient temperature. The PST6250.280-L is placed in the IP20 category for its degree of protection, which protects it against damage from water, impact of foreign objects and dust. When it comes to corrosion, you have to prevent it by ensuring there are no acids, corrosive agents, caustic solutions, metal vapors and salts of large concentrations in the ambient air. The PST6250.280-L is also designed for installation in switchgear cabinets or modular enclosure in category IP54. It allows for integrated temperature monitoring and features an air cooling system.

The PST6250.280-L can only be stored in an environment with a temperature between -25 degrees Celsius and +70 degrees Celsius. One must also prevent moisture from condensing on the PST6250.280-L thyristor power unit. Its humidity class is F, which is 20 degrees Celsius at 90% relative humidity. The fully integrated thyristor power unit does not require many cables or wiring, whether for installation or operation, since most of the needed components have been built in. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
