Product Description

The PSI65C0.637-W1 is an advanced frequency inverter built by the reputable Bosch Rexroth Indramat company specifically for the control of industrial welding transformers. The inverter is a three-phase device designed for recessed mounting. It has a compact housing unit that is classified under the IP20 protection category. The inverter is intended for modular enclosure or installation in a switch gear cabinet that can provide protection that meets the IP54 classification. The housing of the PSI65C0.637-W1 frequency inverter features a slot for parallel, serial or fieldbus interface; there is another slot prepared on the product for retrofitting. There is a temperature monitoring unit integrated into the housing of this product, the inverter also has a water cooling system that helps to maintain its operation temperature below 30 degrees Celsius.

The PSI65C0.637-W1 frequency inverter can be connected in parallel and operate with a maximum of three additional units; the line voltage connection it requires for operation is between 400 to about 480 volts. The voltage frequency should also be about 50/60 hertz. Also, the nominal system current of this product is about 660 amperes>, while the maximum output current is measured to be about <<2400 amperes. The PSI65C0.637-W1 operates with a maximum secondary current of about 120 kiloamperes.

The weld timer and the Input/output interface of the PSI65C0.637-W1 requires a voltage supply that falls between the range of 19 to about 30 volts according to EN 61131-2, alternatively power supply from the weld current system can be used. The clock frequency of the PSI65C0.637-W1 is 1 kilohertz, the product is also equipped with a Metal Oxide Varistor for Over voltage protection. The maximum power loss in the switchgear cabinet of this product is about 100 watts.
