Product Description:
The PSI6100.334-L2 is an inverter module manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. Designed for medium-frequency power conversion in industrial automation, it supplies regulated energy to induction heaters, melting equipment, and other processes that require variable output from a high-voltage, three-phase network. The module integrates control electronics with a fieldbus-ready timing section, reducing the number of separate components required in the cabinet. It also supports coordinated operation with drives and PLCs on the plant floor.
The inverter accepts a supply ranging from 480 to 690 VAC at 50 or 60 Hz, allowing connection to common industrial power networks without an external transformer. An internal auxiliary source delivers 24 VDC at a maximum current of 2 A for contactors, sensors, or gateway electronics. Heat generated by semiconductor switching is removed through air circulation, and power loss is limited to 360 W for cabinet ventilation planning. The climatic classification is 3K3 under EN 60721-3-3, allowing operation under the moderate humidity and vibration conditions commonly found in machine halls. A dedicated INTERBUS timer synchronizes firing patterns and status messages with the higher-level controller, eliminating the need for additional timing relays.
The enclosure has an IP20 protection rating, which guards against accidental finger contact with live components, but the module must be installed inside a closed electrical cabinet. The air-cooled power section requires filtered airflow across the heat sink and does not need liquid cooling lines. Continuous operation is permitted at ambient temperatures from +10 to +55 °C, while the permitted storage range extends from -25 to +70 °C to protect components when the unit is not operating. With a mass of 21 kg, the mounting surface and cabinet supports must be suitable for the module’s weight. Adequate clearance around the air passages helps prevent recirculation of heated exhaust air and supports consistent cooling during sustained operation.
