R911171464
The R911171464 (PST625E.133-W) is a sophisticated Bosch Rexroth Indramat weld controller honoring variant 133 specification. Built for resistance welding, it handles power ratings of 155 kVA and incorporates an advanced temperature monitoring unit. The controller, weighing nearly 8 kgs, incorporates a thyristor power unit for heat generation, and a weld timer for exceptional process supervision. It offers a nominal rated current value of 230 Amps with a maximum duty cycle rating of 50%. This model includes a voltage-dependent resistor (metal-oxide varistors) to shield sensitive components in overvoltage situations.
This unit provides flexibility in installation as it fits a switchgear cabinet or an enclosure and can be mounted vertically or on its rear side. It uses water-cooling with a minimum flow rate of 4L/min and maintains a maximum pressure drop of 0.2 bar. It also features an optional programming interface. The R911171464 (PST625E.133-W) design meets the IP 20 material protection category while its electrical connections and mains supply are facilitated via a box terminal, capable of handling up to a 95mm2 core cross-sectional area. The operational air pressure aligns with installations situated between 0 – 2000 meters a.s.l, and the maximum surrounding air temperature should not exceed 55 °C. It can deliver a primary output reaching 400 Amps at a 30% duty cycle. Storage and transport temperatures should ideally be -25 to 70 °C.
