Wake Industrial LLC is not an authorized distributor of this product.
The Bosch Rexroth Indramat PSI6100.114-W1 is part of the PSI Frequency Inverters series and weighs approximately 25 kilograms. This medium frequency inverter features water cooling, an integrated power supply unit with a maximum output current of 2 A at 24 VDC, and supports mains voltages from 400 to 480 VAC at 50 or 60 Hz. It offers IP20 protection and operates in temperatures ranging from 10 to 55 degrees Celsius.
Internal Product Review
The PSI6100.114-W1 is a Bosch Rexroth Indramat medium frequency inverter with water-cooled thermal management and IP20 protection. Operation on 400 to 480 VAC at 50 or 60 Hz supports clean integration into standard industrial power systems. An integrated 24 VDC power supply rated to 2 A adds practical control-side utility and rounds out a very capable inverter package.

Product Description:
The PSI6100.114-W1 medium-frequency inverter is manufactured by Bosch Rexroth Indramat as part of the PSI Frequency Inverters series. It is intended for installation in industrial control cabinets, where it converts three-phase utility power into a regulated medium-frequency supply for automation loads such as induction generators, heating coils, or specialized drive systems. The unit integrates its own low-voltage supply and monitoring logic, allowing machine builders to connect it directly to the plant mains and cooling network without additional subassemblies.
The inverter accepts a three-phase input of 400–480 VAC at 50/60 Hz, making it compatible with common European and North American distribution grids. Internal semiconductor heat is removed through a water-cooled base plate, and the process coolant must carry away up to 420 W of thermal losses to maintain safe junction temperatures. All power and control electronics are housed behind an IP20 cover that prevents accidental contact but requires placement inside a sealed electrical enclosure for protection from dust and moisture. The unit operates as a medium-frequency inverter, and its design keeps switching stresses within the limits for this power class. This arrangement also helps minimize conducted emissions on the mains.
A dedicated 24 VDC rail, rated at 2 A, powers the internal logic and the 24 V timer circuit, removing the need for an external supply module. Continuous operation is permitted from +10 °C to +55 °C, while the storage and transportation range extends from -25 °C to +70 °C. Compliance with climatic category 3K3 under EN 60721-3-3 confirms suitability for rooms with moderate humidity and limited dust. Despite the integrated coolant channel, the assembly weighs 25 kg, so the cabinet mounting points must support the static load without deformation. Adequate structural support is required to keep the inverter secure during normal machine operation and vibration.
