Product Description:
Bosch Rexroth Indramat manufactured the PSI64C0.733-W1. This 3 phase inverter is designed to optimize industrial metal welding processes. It has a max output current of 400A and a continuous thermal current of 110A to deliver high power while maintaining thermal stability. Its robust construction allows it to operate in an ambient temperature range of -20°C to +70°C making it perfect for harsh industrial environments. It also has an Ethernet/IP communication interface for easy data exchange and remote system integration. One of the key features of the PSI64C0.733-W1 is its advanced thermal management system, which uses water cooling to dissipate heat.
The unit needs 4 liters per minute of water at a max temperature of 30°C to remove excess thermal energy and maintain stability. This is important because excessive thermal buildup in power electronics can reduce efficiency and cause component failure. The inverter’s basic switchgear cabinet loss is 69W, and the max cooling loss is 420W. Under full load, the switchgear cabinet loss is 110W, so the system needs to dissipate heat efficiently to prevent thermal overload and maintain performance. The PSI64C0.733-W1 is designed to be installed in modular enclosures or switchgear cabinets and meet IP 54 protection standards. It can be mounted vertically or backplate mounted and can accommodate a wire size of 35 mm² for secure electrical connections with minimal resistive losses.
The inverter’s nominal system current is rated at 110A to sustain long operation without overheating. For added system safety and longevity it has integrated temperature monitoring and overvoltage protection to mitigate the risks of power fluctuations. The electrical specs of the PSI64C0.733-W1 are all about efficiency and reliability. It runs on a 24 VDC power supply and consumes 300 mA so it’s low power consumption compared to its output. It operates at a clock frequency of 1 kHz which is important for power modulation in welding applications. It weighs around 25 kg so it’s robust and compact design balances mechanical stability with ease of integration in automation. It can withstand ambient temperatures up to 55°C so it’s heat resistant and still operating.
