Product Description:
The PSI64C0.780-W1 medium-frequency inverter is manufactured by Bosch Rexroth Indramat and is part of the PSI Frequency Inverters series. Installed inside a control cabinet, it converts three-phase utility power into a variable-frequency output for induction heating or similar automated processes that require tightly regulated energy delivery. A water-cooled structure is used so heat is removed directly at the power stage rather than into the surrounding air.
The inverter accepts a supply of 400 – 480 VAC and draws up to 220 A from the mains, so incoming conductors must match the specified connection cross-section of 95 mm². Dissipated heat inside the enclosure is minimized by cabinet losses of 210 W, while the liquid circuit can carry away as much as 700 W when water is circulated at the minimum rate of 4 l/min. A pressure drop of 0.6 bar at that flow shows the low hydraulic resistance of the cooling channel, allowing the unit to share a plant chilled-water manifold. To maintain airflow around auxiliary electronics, the maker recommends 100 mm of ventilation clearance at the top and bottom of the cabinet.
The unit has a primary current limit of 1600 A and a secondary peak of 54 kA when paired with the PSG 3100 transformer, giving ample headroom for short, energy-dense heating cycles. The housing carries a protection rating of IP20, so it must be mounted in a closed enclosure but does not require additional gasketing. An integrated power-supply unit delivers 24 VDC at 2 A for control relays and sensors, and timing of heating pulses is handled through an EtherNet-based timer interface. Water enters and leaves through an M16 × 1.5 threaded pair, switch-cabinet standby losses are limited to 69 W, and overall dimensions of 653 mm × 288 mm × 280 mm simplify placement alongside other drive components.
