Product Description:
The PSI63C0.780-W2 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase mains power into a controllable medium-frequency output for specialized loads in automated production lines. Designed for cabinet installation, the unit combines power conversion and an auxiliary supply in one housing, reducing space requirements and wiring effort in industrial automation systems.
The inverter accepts a three-phase input of 480 to 690 VAC and operates on utility grids running at 50 or 60 Hz. This wide input range permits operation on 480 V U.S. supplies and higher-voltage European feeds without transformer tap changes. Heat generated by the power electronics is removed through a sealed water circuit, and the external chiller must dissipate a maximum power loss of 420 W. Direct liquid contact with the baseplate provides greater thermal conductivity than air cooling and helps control the temperature of internal components during operation. A built-in auxiliary supply delivers 24 VDC at up to 2 A for contactors, sensors, and control relays, eliminating the need for a separate power module. Timing data and diagnostic information are exchanged through an Ethernet interface, enabling coordinated process triggers and communication with the control system.
The enclosure has an IP20 degree of protection, so the inverter must be installed inside a closed electrical panel that prevents unintended contact with internal components. The electronic components meet the 3K3 climatic category under EN 60721-3-3 and can operate from +10 °C to +55 °C in noncondensing conditions. Storage is permitted from −25 °C to +70 °C when the inverter is not operating. The unit weighs 25 kg, which limits the load placed on panel mounting hardware and should be considered when selecting supports and fasteners. Adequate clearance around the housing allows access to the electrical connections and supports proper routing of coolant lines within the cabinet.
