Product Description

Bosch Rexroth is an automation firm that produces high quality power and control units.

The PST6250.100-L is a three phase thyristor unit produced by the company. The device has been designed for the transformers belonging to the 250 kVA category. This device has a rated current of 110 A and has a 400 to 600 Volts rated voltage. This thyristor power unit serves to control the welding transformer. The device has multiple integrated features that enhance its functionality. A weld timer is also integrated that serves as a central processing unit. An additional slot has been built-in in which a quality module can be installed. Optionally, a slot can be utilized to install the Fieldbus for programming. A type-specific I/O interface can be integrated into another slot. The integrated control functionality improves the operational efficiency of the system. The various components of this system have been fully integrated so additional cabling requirements are minimum.

The PST6250.100-L provides a platform for easy programming and comes with an extensive diagnostics suit. These functions are provided with the B0S-5000 operator interface built into this device. This device has an air-cooled design to maintain an optimum temperature. The device has been designed for recessed mounting and requires a two-phase connection. The device itself has an IP 20 standard ingress protection and can be installed in switchgear cabinets that have an IP 54 protection standard. This model has a 200 A nominal system current and falls in the humidity class F. A 400 V to 600 V line voltage connection is needed for this power unit. It can be easily stored and transported in areas having external temperatures from -25 ᵒC to 70 ᵒC. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
