Product Description:
The PSI6200.350-W1 belongs to the PSI Frequency Inverters series produced by Bosch Rexroth Indramat. As a medium-frequency inverter, it supplies adjustable electrical energy to induction heaters, spindle drives, and other automation loads that operate above standard line frequencies. The unit integrates with cell controllers through an INTERBUS timer interface, enabling coordinated start, stop, and power-level commands within distributed manufacturing lines. This communication link allows the controller to synchronize the inverter with other equipment during automated production sequences.
The power section accepts three-phase input from 400 to 480 VAC networks and processes 50 or 60 Hz utility service without additional transformers. Thermal regulation is handled by a water-cooled jacket that directs coolant across the heat sink base. This cooling system transfers the inverter’s maximum cooling losses of 420 W to an external chiller instead of releasing that heat into the control cabinet. A built-in supply delivers 24 VDC for logic circuits, and its auxiliary output can provide up to 2 A to field I/O, gate drivers, or small relays. These electrical and cooling characteristics support climatic category 3K3 under EN 60721-3-3, which is suitable for machine halls where moderate humidity and dust may be present but condensation must be prevented.
The enclosure carries an IP20 degree of protection, making live parts finger-safe when the inverter is mounted inside a filtered cabinet. The coolant loop keeps semiconductor junctions within their operating limits across a temperature range of +10 to +55 °C. For storage or transportation, internal components tolerate temperatures from -25 to +70 °C without performance degradation. The chassis has an approximate mass of 25 kg, which supports stable panel mounting and helps reduce vibration during operation. Adequate cabinet clearance, secure mounting hardware, and an uninterrupted coolant supply are necessary to maintain proper airflow around adjacent components and effective heat transfer through the inverter’s cooling jacket.
