Product Description:

The PSI 6300 63C0.728L1 by Bosch Indramat is a 3-phase medium Frequency Inverter. The frequency inverter exists as a modular device that is engineered for mounting inside control cabinets. Time control functions come included with this frequency inverter as an integrated weld timer system.

The PSI 6300 63C0.728L1 Frequency Inverter provides an installation slot that connects to either parallel, serial or fieldbus I/O interface. An extra retrofit-ready quality module slot exists that users can install. The inverter operates with air cooling and contains built-in temperature control capabilities. The ambient temperature can reach up to 55°C but reduces to 45°C when using a Bosch fan cowl. Storage conditions allow between -25°C and +70°C. The component operates under 90% humidity at 20°C parallel to 50% at 40°C in line with DIN 40040 and VDE 0113 specifications. The frequency inverter requires no moisture condensation during its operational period. The PSI 6300 63C0.728L1 Frequency Inverter functions best in electrical voltage ranges between 400 V −20% to 480 V +10%. The equipment operates at 50/60 Hz frequency and allows connection to two different grounded systems: TN or TT. The inverter produces a nominal thermal current flow of 110 A and achieves maximum output currents that reach 800 A.

The PSI 6300 63C0.728L1 Frequency Inverter enables secondary current output to reach 36 kA through its combination with a PSG 3100 transformer. The frequency inverter runs a clock frequency of 1 kHz inside the system. The PSI 6300 63C0.728L1 implements metal oxide varistors as its overvoltage protection mechanism. The control voltage fulfills the EN 61131-2 requirements for standards. The weld current system has two sources of power either from within itself or through external inputs. The supported conductor cross-section reaches a maximum of 50 mm². The wire size standard for this frequency inverter is set at 35 mm².
