R911170878
The R911170878 (PST610-EW), crafted by Bosch Rexroth Indramat, is an AC power source designed for use with welding transformers. Utilizing a thyristor-controlled rectifier bridge, it converts secondary voltage to a square wave arc voltage, the result of which delivers superb strike characteristics and high-quality welding properties. This power unit overcomes the limitations of previous welding machines by offering enhanced semiconductor design with automatic control and monitoring capability. It incorporates a two-phase full wave bridge rectifier driven by a pair of silicon controlled rectifiers, offering exact triggering at precise firing angles for an accurate and sharp weld arc.
This Thyristor Power Unit, boasting an integrated weld timer, can operate with welding transformers up to 76KVA. Its BOS-5000 interface offers an easy-to-navigate terminal for programming, operation, and fault diagnostics. Enclosed within a sturdy metal casing, the power unit features embedded system modules, minimizing cabling requirements. Despite high current capabilities, this unit maintains smooth operation, thanks to its air-cooling design and adequate surface heat sink. A ready LED indicator not only signals readiness but also cuts output drive current in instances of malfunction, protecting the system from potential damage. Compliant with IP65 protection standards, this product is well-prepared to meet industrial environmental requirements.
