Product Description
The PST6250.331-L is a Bosch PST 6250 series thyristor power unit. It is designed by Bosch for use with welding transformers. Features of PST 6250 series supplies include integrated control functionality, integrated weld timer, BOS-5000 operator interface for programming, field bus interfaces for communication and flexible serial and / or parallel interfaces. Components of the PST6250.331-L include weld timer and three slots which can be used for I/O interface, field bus module and quality module respectively. The BOS-5000 software can be installed on either a local or host PC and can be used for programming of the PST6250.331-L and for event logging, diagnostics and fault display. Overloading of the power supply can cause damage and must be avoided. All maintenance work should be performed by skilled and trained personnel in compliance with safety regulation and manufacturer recommendations.
A MOV (metal oxide varistor) is integrated into the PST6250.331-L for overvoltage protection. The rated input voltage range is 400 to 600 Volts AC. The supported line frequency range is 50 to 60 Hertz. The maximum rated thermal current is 200 Amps. Weld timer on the supply requires nominal 24 Volts DC supply. The maximum rated duty cycle for the power supply unit is 50%. The basic switchgear cabinet loss is 70 Watts. A cutout measuring 448 x 255 millimeters is required for installation of the PST6250.331-L. Shipping weight and dimensions of the supply unit are 12.5 kilograms and 463 x 280 x 239 millimeters. The PST6250.331-L is an air cooled power supply. Maximum ambient temperature for operation is 113 degrees Fahrenheit. The temperature range for storage is from -12 to 158 degrees Fahrenheit. The ambient relative humidity at 68 degrees Fahrenheit should not exceed 90%. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
