Product Description:
Bosch Rexroth Indramat supplies the PSI62C0.758-W1 as a member of the PSI Frequency Inverters series. This medium-frequency inverter converts three-phase utility power into a controlled output that allows machine controllers to regulate induction-heating or hardening coils without mechanical switching. Within an automation line, the unit delivers regulated current and frequency so that workpieces reach a precise thermal profile before moving to the next station.
The inverter is designed for a mains voltage range of 400–480 VAC and operates at either 50 or 60 Hz, enabling direct connection to common industrial power grids. Internal assemblies have an IP20 protection rating, so the unit must be installed in a suitable cabinet and is protected against accidental finger contact with hazardous internal parts. Heat generated by the power electronics is extracted through a water-cooled baseplate; this liquid circuit limits panel temperatures and keeps the semiconductors within their safe operating range. A built-in power supply provides auxiliary controls with a stabilized output of 24 VDC, removing the need for an external 24-volt source and simplifying wiring to sensors, contactors, or fieldbus interfaces.
The inverter meets climatic class 3K3 under EN 60721-3-3, allowing operation in industrial environments with moderate humidity. Cooling water removes up to 420 W of thermal loss from the power electronics. The integrated power supply can deliver up to 2 A to connected control peripherals. The permitted operating temperature ranges from +10 to +55 °C, while the electronics can withstand temperatures from -25 to +70 °C during storage or transportation. An Ethernet-based timer function coordinates dwell periods with supervisory controllers, supporting controlled process timing during heating or hardening cycles. The components are assembled in a chassis that weighs 25 kg and is intended for secure mounting inside a drive column or equipment rack.
