Product Description

The PST6100.114-L thyristor power unit is one of the latest productions of Rexroth Indramat. The device is designed to aid the smooth operation of  AC resistance welding industrial applications by controlling the flow of electric current into the welding transformers. The thyristor acts as a switch and also offers adequate protection to the power circuit of the AC welding systems. The PST6100.114-L thyristor power unit is renowned for its durability, rigidity and its ability to stimulate quality welding optimization in industrial applications. The thyristor power unit’s control unit and its monitoring unit operates independently of each other. The PST6100.114-L thyristor power unit does not require complicated cabling to perform optimally; this is because of its unique system component integration design.

The PST6100.114-L thyristor power circuit is very efficient; it has a rated current of 110 Amperes and a rated voltage of between the range of 400 to 600 Amperes. The drive is air-cooled, thus should be strategically installed vertically in a position that exposes it to enough cool and dry air that will help to regulate the heat produced by the thyristor. The resistor should only be operated in industrial environments that meet the DIN EN 50082-2 and 50081-2 requirement on electromagnetic compatibility. The thyristor can tamper with cardiac pacemaker devices; thus special “keep off” signs should be installed around the drive to warn operators. The thyristor contains a heatsink which helps in the process of temperature regulation. It also features a built-in battery.

The PST6100.114-L power unit can be damaged by overloading and irregular supply of power. To prevent unnecessary machine failure, operators should constantly check and address the diagnostic error messages usually displayed on the Bosch operator interface. The drive should be installed vertically for optimal operation. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
