The Bosch Rexroth Indramat PSI62C0.757-W1 is a medium frequency inverter from the PSI Frequency Inverters series. It is water cooled, has an IP20 degree of protection, and operates with a mains voltage range of 400 to 480 VAC at 50 or 60 Hz. The integrated power supply unit delivers a maximum output current of 2 A at 24 VDC, and the inverter weighs approximately 25 kg.
Internal Product Review
The PSI62C0.757-W1 is a medium frequency inverter with water-cooled thermal management that gives the platform a refined heat-handling profile. An integrated 24 VDC power supply with 2 A output simplifies support circuitry and adds practical value in panel applications. A 3K3 climatic category and a +10 to +55 °C operating range make the inverter a strong fit for controlled industrial environments.

Product Description:
The PSI62C0.757-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It converts fixed utility power into a regulated high-frequency output that drives induction coils, transformers, or other resonant loads used in automated production lines. By adjusting frequency and voltage, the unit allows the electrical energy to be matched to the operating characteristics of heating stations, test rigs, or specialized machinery without mechanical gear changes. This electronic regulation supports process adjustments without requiring changes to the connected mechanical equipment.
The power section accepts a three-phase supply of 400–480 VAC at 50 or 60 Hz, so it connects directly to common plant mains. Internal circuits are water-cooled, and the enclosure is rated at IP20, providing finger-safe protection when the unit is installed inside a control cabinet. An integrated auxiliary supply delivers 24 VDC with a peak current of 2 A. This auxiliary rail can power relays, sensors, or a fieldbus node without requiring a separate 24-volt supply. Cooling water removes heat from the semiconductors instead of releasing hot air into the cabinet, which reduces internal temperature rise and permits closer spacing between drives. A built-in Ethernet timer function synchronizes frequency ramps or dwell periods with commands received over the control network, supporting coordinated startup sequences.
Maximum cooling losses are 420 W, so the connected heat exchanger must be able to remove that amount of heat under full load. Continuous operation is permitted from +10 to +55 °C, while storage or transportation is permitted from -25 to +70 °C. The inverter meets climatic category 3K3 under EN 60721-3-3, covering the humidity and condensation conditions commonly found in switch rooms. At approximately 25 kg, the unit has a manageable cabinet-mounted form but still requires secure panel attachment to withstand vibration from connected equipment. Adequate water flow and cabinet clearance are necessary to maintain heat transfer around the inverter during sustained operation.
