Product Description:
The PSI64C0.630-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. The unit converts three-phase mains power into controlled output current to drive induction heating coils, welding transformers, or similar loads in automated production cells. By tracking programmed command values, it supplies repeatable energy bursts that allow precise thermal or metallurgical processes to be synchronized with motion sequences on the factory floor.
Input power can come from any three-phase source from 400 – 480 VAC, while internal logic and contactors are fed by a separate 24 V DC control circuit. Current setpoints are digitized with a 10 A resolution, so the inverter can modulate its output up to the maximum command current of 250 kA for short-duty pulses. Heat generated by the IGBT stack is removed through a water-cooled plate, allowing full-rated operation without derating. The device delivers a 20 mA pressure-proportional signal for external regulators, and its X1 9-pin D-Sub connector carries DeviceNet timer lines that coordinate firing sequences. A lithium AA backup battery maintains parameter memory when input power is absent.
Configuration resources include a program capacity of 256 steps, a spot capacity of 1,048,576 counts, and an electrode capacity of 5, while the impulse counter halts operation after 9 commanded shots for inspection cycles. Operating altitude is permitted up to 2000 m under the 3K3 climatic category, and continuous output is allowed until the heat sink reaches 55 °C. The enclosure rating is IP20, so the inverter must be mounted inside a cabinet with forced airflow. Parameter retention relies on the 3.6 V cell mounted on the control board. The inverter must be installed within the stated temperature and voltage limits to protect internal semiconductors and maintain insulation clearances.
