Product Description:
The PSI65C0.787-W1 Frequency inverter is designed for industrial automation applications requiring precise power conversion. It operates within a line voltage range of 400 to 480 V and supports heavy duty electrical systems. It is manufactured with high quality materials and provides a reliable power supply for industrial transformers and high current applications.
This PSI65C0.787-W1 frequency inverter supports a mains voltage tolerance of – 15 % at 400 V and + 10 % at 480 V. The maximum thermal continuous current of this model is 330 A without cabinet cooling and 660 A with cooling. The primary current output to the transformer reaches 2400 A while the secondary current peaks at 120 kA when using a PSG 3100 transformer. Electrical connections of this frequency inverter require 2 to 4 cables with a cross section of 120 mm² each to handle high power loads efficiently. The switch cabinet incurs basic losses of 100 W and operates at a maximum loss of 850 W. Maximum cooling losses of this model reach 4400 W that ensures system stability under high power loads. The minimum water cooling flow rate is 10 l/min with a typical pressure drop of 0.65 bar at this flow rate across both coolers. This PSI frequency inverter is specifically designed for industrial applications that demand high power and stable voltage conversion.
The Bosch Rexroth Indramat PSI65C0.787-W1 frequency inverter is built to be mechanically separated if needed with a weight of approximately 70 kg. Power for this model is connected via cable lugs using an M10 screw per connection. This ensures a secure and stable electrical link. The required tightening torque for connections is between 41 and 46 Nm. This frequency inverter’s cooling system ensures efficient thermal management and reduces the risk of overheating during extended operation.
