Product Description:

For use in industrial automation, Bosch Rexroth Indramat developed the PSI61C0.752-L1, a medium-frequency inverter. A member of the PSI 6000 series, the inverter combines a power supply with a welding timer for optimal performance. Seam, projection, spot, and repeat mode resistance welding are all possible with this frequency inverter.

The PSI61C0.752-L1 medium frequency inverter can handle three-phase power at 50/60 Hz and runs on a 400V system voltage. The inverter's normal operating voltage range for the DC connection is 550 V to 680 V. The precision needed for welding operations is provided by its 1000 Hz clock frequency. The inverter's two CAN ports make it easy to connect to and communicate with networks. Because of its air-cooled architecture, it effectively manages heat. Operational safety and dependability are both improved with integrated overvoltage protection. The need for a distinct TB712 terminal block streamlines installation and allows for safe and efficient mounting. To ensure its longevity and optimal performance, it is designed to work in an environment free of high concentrations of acids, metal vapors, and corrosive chemicals. Its versatility for demanding tasks is further enhanced by its ability to supply a maximum secondary current of 20 kA.

Designed for versatility in varied situations, the inverter has a storage temperature range of -25°C to +70°C and a maximum ambient operating temperature of 55°C. Optimal operating safety and easy integration with existing systems are guaranteed by the PSI61C0.752-L1 medium frequency inverter. The inverter is the best option for industrial purposes all over the world because of its reliability, that is further enhanced by its worldwide shipping services and one-year replacement warranty.
