Product Description
The PST6250.333-L is a thyristor power unit with an integrated control function manufactured by Bosch Rexroth Company. It is intended for the connection of metal welding transformers in industrial environments. Only technicians and engineers with special skills and training should commission, install, and maintain this unit. It features a BOS-500 operator interface that allows quick operation, programming, and diagnostics. Thanks to the task-specific functionality, it provides quality welding optimization. Other features include an air cooling system, separate monitoring and control functionality, Fieldbus interfaces for communication, and an integrated weld timer.
The PST6250.333-L serves to control the welding transformers through a welding timer, I/O interfaces, field bus module, and an optional quality module. Together with a welding transformer and weld timer the thyristor power unit alternates current resistance welding. It features monitoring functions that ensure high reliability for improved performance. The integrated thermostatic switch prevents overload by blocking further sequence when the temperature of the unit exceeds 80 degrees. The PST6250.333-L is vulnerable to malfunction should the current parameters surpass the maximum pre-determined current and should there be mains voltage surges. Other reasons include incorrect electrical connection and insufficient cooling. Thanks to the LEDs, you can easily tell instances of unit malfunction.
The PST6250.333-L features ambient conditions such as an operating temperature of 55 degrees, a storage temperature of -25 to 70 degrees, installation elevation of 2000 meters above sea level, and a maximum permissible relative humidity of 90%. It comes with an IP 20 protection category. This makes is susceptible to water entry and extrinsic objects. It should be mounted in a switchgear cabinet with an IP 54 category with air cooling of a maximum of 45 degrees. It weighs approximately 12.5kg. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
