Product Description:
The PSI62C0.737-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase mains power into a high-frequency output for precise energy delivery in automated processes. Controlled primary and secondary current loops are supervised by its TriCore processor, while the EtherNet/IP interface coordinates operating sequences with plant controllers.
On the input side, the inverter accepts a line voltage range of 400–480 VAC and draws a nominal current of 220 A. During short duty peaks, its DC link can carry up to 1200 A of primary current without exceeding the design limits. The internal clock generates output sequences at 1000 Hz, and an Ethernet timer synchronizes this rate with the required weld pulses. Field wiring for the power terminals requires conductors with a cross-sectional area of 95 mm² to control temperature rise. An integrated 24 VDC rail supplies the control electronics, and the TriCore CPU manages command exchange over EtherNet/IP. Diagnostic monitoring includes a pressure-feedback timeout of 5 seconds and a weld-contactor check window of 250 milliseconds. The inverter stops operation if either monitored response exceeds its permitted time window, helping prevent an output sequence from continuing after a delayed system response.
Water cooling removes up to 700 W of heat, and the circuit requires a minimum coolant flow of 4 L/min to stabilize the semiconductor junctions. The cooling path carries heat away during repeated high-current pulses and reduces the thermal load transferred directly into the surrounding cabinet. Cabinet heat dissipation is 69 W under light load and rises to 210 W at maximum inverter output, allowing the enclosure heat exchanger to be sized for the expected operating load. On the secondary side, the transformer can deliver current as high as 54 kA, while the stop circuit is rated for 24 VDC at 3 A to hold the contactors during an emergency shutdown.
