Product Description:
The PSI6100.321-L1 frequency inverter is from Bosch Rexroth Indramat. This is a rugged unit for resistance welding in harsh industrial environments. It’s a 3-phase medium-frequency inverter with built-in control. Rated voltage 400 to 480 volts, rated current 110 amps. This will handle the power of most industrial environments. A key spec is the max output current of 400 amps, which is the current the inverter can deliver for welding. When paired with the PSG 3100 welding transformer, it can do 20 kA secondary current, which is for high-power welding. It’s air-cooled, which is a good way to manage heat in industrial environments. The max cooling losses is 360 watts, which is how much heat the cooling system can dissipate.
The PSI6100.321-L1 can be installed in a modular enclosure or in switchgear cabinets with IP54 protection when installed properly. This will protect the unit from dust and water splashes, which is important for industrial applications. It also has a slot for parallel, serial or fieldbus I/O interface for communication and integration with other automation devices. It also has a slot for a quality module for future upgrades. The inverter has a clock frequency of 1 kHz, which is the speed the inverter can perform its control function. It has a metal oxide varistor for overvoltage protection, which is a must-have for the inverter. The wire range is 35 mm², which is the recommended cable size for safe and efficient current transfer.
The inverter’s internal power consumption is basic switchgear cabinet loss 100 watts and switchgear cabinet loss at max power 200 watts and the core is powered by Intel Atom E3815 1.4 GHz with 2GB DDR3 SDRAM. The PSI6100.321-L1 can be mounted either vertically or with its back against a mounting plate. A key operating parameter is the ambient temperature, which should not exceed 55°C for optimal performance and longevity of the inverter. The dimensions are 130 mm x 100 mm x 100 mm. The inverter software is based on Windows 10 IoT and has I/O interfaces of 4x USB 2.0, 2x CAN, 1x Ethernet. The protection class of the unit itself is IP20.
