Product Description:
The PSI6100.420-W1 belongs to the PSI Frequency Inverters series manufactured by Bosch Rexroth Indramat. Classified as a medium-frequency inverter, it converts fixed three-phase mains power into a controllable output that drives induction heating or other high-frequency loads used in automated production lines. Its integrated auxiliary supply supports the control electronics, allowing the unit to be installed as a single package in cabinets that coordinate power conversion with PLC-based process control.
The inverter expels heat through a water-cooled circuit that lowers noise and reduces enclosure airflow requirements. All live parts are enclosed in an IP20 housing, so the inverter must be mounted inside a cabinet while remaining protected against accidental finger contact. An onboard switch-mode power section delivers 24 VDC at up to 2 A, providing power for sensors or gate-drive logic without an external supply. The main input accepts three-phase 400–480 VAC, allowing the device to connect directly to common industrial power systems without a transformer. During operation, the water jacket dissipates 420 W of cooling losses, which must be considered when sizing the heat exchanger or chiller circuit.
Electrical excitation can be synchronized with either 50 or 60 Hz plant power, allowing the same model to operate with either standard frequency. Continuous operation is permitted from +10 to +55 °C, matching the 3K3 climatic category under EN 60721-3-3. Storage or transportation is permitted from -25 to +70 °C when the inverter is not operating. The unit has a mass of approximately 25 kg, so the cabinet structure and mounting hardware must be suitable for its weight. Adequate support also helps keep the inverter securely positioned when the surrounding machinery produces vibration.
