Product Description

The PST6250.201-L is a solid-state AC semiconductor-like power unit (thyristor) produced by Rexroth Bosch. This equipment is intended for use with a welding transformer, and it provides the adequate power supply for metal resistance welding. It is suitable for industrial applications as specified by EN 50178, EN 50081-2, EN 60204-1 and EN 50082-2. It is only recommended for use in residential environments if it doesn’t interfere with the operation of other equipment.

Any non-intended use of the PST6250.201-L could result in injuries to operating personnel, damage to equipment and to the environment. The integrated PROFIBUS weld timer of this equipment aids the regulation of power supply and finds application in seam welding, spot welding and projection welding. The timer monitors welding processes with respect to current and time variables. The starting current of the weld timer of the PST6250.201-L is approximately 1.5 Amperes for 10 millisecs. The operating temperature range of this equipment is between 0 – 55 degrees Celsius, and its climate category is 3K3, as per EN60721-3-3. By mass, the approximate weight of this model is 13 kg, and its max. cooling temperature is rated 45 degrees Celsius.

The design of the PST6250.201-L is such that it can be installed in gear cabinet (with protection class IP 45) or modular enclosure with protection class IP 20. The air pressure range of this PST 6250 version is between 0 to 2000 meters above sea level. The nominal current of the system is 200 A, and its maximum duty cycle is permitted up to 50 %. This device has a clock frequency of 50/60 Hz, and its overvoltage protection mechanism is facilitated by non-linear metal-oxide varistors (MOVs). This unit can be shipped globally with a one-year warranty period from Wake Industrial.
