Product Description:
Bosch Rexroth Indramat supplies the PSI62C0.752-W1 as part of its PSI Frequency Inverters series. Classified as a medium-frequency inverter, it reshapes three-phase utility power for induction heating heads, welding transformers, and other high-current loads found in automated production cells. A TriCore CPU executes control loops, while an Ethernet I/O port and an Ethernet-based timer channel synchronize the unit with PLC sequences. The internal auxiliary rail supplies 24 VDC at 2 A, simplifying field wiring by powering relays and sensors directly from the inverter cabinet.
The input section accepts a line voltage range of 400 to 480 VAC at industrial frequencies of 50 or 60 Hz. It draws a continuous 220 A when operating at rated output. After rectification, the inverter modulates its H-bridge at a primary drive frequency of 1 kHz, producing a medium-frequency waveform for downstream converters. An IP20 enclosure protects the electronics against contact with fingers and solid objects larger than 12 mm. Power terminations accommodate copper conductors with cross-sectional areas of up to 95 mm². The processor manages fault monitoring, load sharing, and parameter storage, while the Ethernet service port provides access to the unit’s controls.
Thermal energy is removed by a water-cooled heat sink. The circuit dissipates up to 700 W under full load, while auxiliary sections add 420 W during extreme duty cycles. Proper operation requires a coolant flow of 4 L/min, which produces a pressure drop of 0.6 bar at that rate. Peak primary current can reach 1200 A, and the associated medium-frequency transformer can carry up to 54 kA on its secondary side. The inverter operates within an ambient temperature range of +10 to +55 °C and belongs to climatic category 3K3. Storage temperatures can range from -25 to +70 °C. The steel frame measures 653 mm high, 288 mm wide, and 280 mm deep, and the unit weighs 25 kg.
