Product Description:

The PSI6300.357-L2 Medium-Frequency Inverter Drive from the Bosch Rexroth Indramat manufacturer is a high-grade drive designed for medium-frequency welding applications. Rexroth stands as a symbol of precision and innovation which aids in delivering cutting-edge solutions that redefine industrial automation performance.

This PSI6300.357-L2 medium-frequency inverter drive operates with an input voltage range of 500-690 VAC and holds an integrated lithium battery inside which is rated at a voltage of 3.6 V. This ensures a discharge time of up to 5 minutes. This drive is optimized for 3-phase MF inverter systems which are specifically engineered for recessed mounting types. Designed for air-cooled operation mainly as an L2 type, the inverter drive maintains efficient thermal management with a heat sink positioned at the rear. The maximum allowable cooling losses occur at a power of 360 W while the power switch experiences a cabinet loss of 200 W. The PSI series drive’s tightening torque requirements meet a secure range between 6 and 8 Nm which is needed for motion control. It supports a maximum input current of 110 A and consists of electrical connections via box terminals with conductor cross-sections between 35 mm² (minimum) and 50 mm² (maximum).

This PSI6300.357-L2 frequency inverter drive has a current consumption of 800 A at the output side and meets high-demand welding transformer requirements for multiple power supply modes. The maximum permissible temperature for high-performance is found to be 45°C which helps in ensuring reliable functionality even in demanding conditions. Weighing just 20.9 kg approximately 21 Kg, this inverter drive is designed to withstand multiple setups with a 1-year replacement warranty from Wake Industrial in case of any issue.
