Product Description

Bosch Rexroth is an engineering company famous for its top quality motion control products and control units.

The PST6100.680-L is a thyristor unit produced for welding transformers. The welding transformers with a maximum power of 76 kVA are used with this thyristor. The device operates on a 50..60 Hz frequency and has a rated current of 110 A continuous thermal current. This thyristor unit comes with advanced control options because of its integrated control functionality. A weld timer has also been installed in this unit. With integrated temperature monitoring, the device can be used for long periods of time with the danger of overheating. The device has been equipped with dedicated slots that can be used for serial, parallel, or field bus interfaces. This power unit uses the air cooling method for maintaining an optimum operating temperature. It can be used in areas with a maximum ambient temperature of 55 ᵒC.

The PST6100.680-L is protected in accordance with IP 20 standards. With a nominal system current of 130 A, this unit has a line voltage connection of 400 V. This model can be further enhanced because an additional slot has been provided for retrofitting. The PST6100.680-L has been equipped with MOV (Metal Oxide Varistor) that provides significant overvoltage protection. The device has a basic switchgear cabinet power loss of 70 W and has a total mass of around 12.5 kg. Owing to multiple monitoring functions, this thyristor unit has high operational reliability. Error messages are signaled in case of an overload on this unit. The messages can be removed by an input signal for acknowledgment or by a BOS-5000 operator terminal. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
