Product Description

The PSI63C0.737-L1 medium-frequency inverter by Bosch Rexroth features reduced spatter and expulsion because of reduced welding current. The module helps in the integration of light and small transformers into the electric holders. Its wide range of control functions renders high process reliability. This product features a dedicated slot for a parallel, serial, or fieldbus interface. The device should be operated with gloves to avoid the risk of injury due to sharp-edged sheet metal. The unit may be prone to failure due to heat accumulation if the minimum clearance requirements at the top and bottom are not met. The inverter must be allowed to function only under forced-air cooling conditions. The cooling is implemented through a fan cowl from the manufacturer.

The product features an integrated temperature monitoring system. The device must be stored ina temperature range of -25°C and 70°C. Its maximum secondary current is based on the transformer used. The CPU of the weld timer has a voltage rating of 30VDC in compliance with EN 61131-2 specifications. The inverter is quite heavy and therefore, may require assistance for assembly and installation. The unit must be equipped with a safeguard to avoid unintentional reclosing. The module should have appropriate fusing on the side of the mains. The electric connections to this unit should be handled using properly insulated tools.

The protective grounding for the inverter must adhere to DIN VDE 0160 specifications. The unit must not be made to function in unbalanced networks with only one grounded network phase. The control and inverter cables must be routed separately from each other to avoid interference. The U1, V1, and W1 connections should be connected to L1, L2, and L3 system phases respectively. This product must not be modified or retrofitted as this can compromise the safety of the module. The medium frequency inverter can be dispatched to any address globally with a one-year Wake Industrial warranty.
