PST6250.323-L

Product Description

Manufactured by Bosch Rexroth to be applied in connecting welding transformers, the PST6250.323-L is a two-phase thyristor power unit, module designed for recessed mounting. It is one of the power units in the PST 6250 series used in industrial environments only. The PST6250.323-L thyristor unit was also designed to be used in alternating current resistance welding. In AC welding, the important components are a thyristor power unit, weld timer and welding transformer, and the PST6250.323-L is fully integrated to meet these needs. This functionality and integration makes it ideal for quality optimization in welding transformers and easily installation into a welding box system.

This is because it features an integrated control function, which means that most of the components and modules that the PST6250.323-L needs has been integrated into its power unit. These include the weld timer, and other control and monitoring functionality. When it comes to the installation or mounting of the PST6250.323-L, you will have to consult the accessories kit. This kit is available if you choose to mount the power unit by facing its back on the mounting plate. It can also be mounted vertically, and must meet certain ambient conditions and installation elevation requirements for proper functioning.

While the ambient temperature is a maximum of 55 degrees Celsius, the storage temperature is between -25 and +75 degrees Celsius. It must be protected from corrosion by ensuring the ambient air is free from large concentrations of acids, and protects itself against water and foreign objects. The PST6250.323-L features air cooling with the max set at 45 degrees Celsius, and integrated temperature monitoring to prevent overheating. It also warns of overloading through the weld timer and overvoltage with the MOV. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
