Product Description:
Bosch Rexroth Indramat’s PSI63C0.720-W1 belongs to the PSI Frequency Inverters series and functions as a medium-frequency power converter for industrial automation. The unit accepts three-phase utility power and delivers an adjustable medium-frequency output for machine tools, induction heaters, and other loads that require precise energy control. Its integrated low-voltage supply can power auxiliary equipment without a separate supply module. Built-in diagnostics provide operating information that can help identify faults and interruptions in the connected system. These features support centralized cabinet layouts commonly used in automated machining and forming lines.
The inverter connects to plant power at 400 to 480 VAC and operates on 50 or 60 Hz grids, allowing use in multiple regions without changes to the unit. A water-cooled heat exchanger removes switching losses and limits thermal dissipation to 420 W. The enclosure has an IP20 rating, which provides protection against accidental contact but requires installation inside a closed control cabinet. An integrated auxiliary supply delivers 24 VDC at up to 2 A for sensors, relays, or fieldbus repeaters, reducing the need for external wiring. The assembly meets climatic category 3K3 under EN 60721-3-3 and is intended for clean production areas with moderate temperature control. Adequate cabinet clearance and cooling-water circulation are necessary to remove heat from the power electronics during operation.
The inverter remains functional within an operating temperature range of +10 to +55 °C. When not in service, it can be stored or transported at temperatures from -25 to +70 °C without component damage. The chassis weighs 25 kg, providing sufficient mass for stable installation with the water-cooling connections secured. The mounting surface must support the chassis and associated hoses without placing strain on the coolant fittings. Run-time sequencing and frequency profiles are managed through an Ethernet-based timer interface, allowing synchronized operation with upstream controllers. Proper temperature control helps prevent condensation, while secure mounting protects the water connections and internal components from unnecessary mechanical stress.
