Product Description:
The PSI63C0.132-W1 is produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. Classified as a medium-frequency inverter, it modulates three-phase factory power so that induction-heating, welding, or similar process equipment receives a regulated high-current supply. The device is designed for water-cooled cabinet installations and provides local control through a TriCore CPU. Discrete input and output signals connect it to the surrounding automation system.
The inverter produces a base cabinet heat loss of 69 W, while operation at maximum current increases total cabinet dissipation to 110 W. The housing has an IP20 rating, helping prevent accidental finger contact with live parts inside the enclosure. The electrical input range is 400–480 VAC at 50 or 60 Hz, with a nominal current draw of up to 110 A. A built-in 24 VDC supply delivers 2 A for sensors and also powers the internal timer circuitry. Logic signals are exchanged through discrete terminals operating at the same voltage, simplifying connections to a PLC. Under worst-case duty conditions, the liquid cooling circuit must remove up to 420 W of heat.
The power stage accepts copper conductors with a cross-sectional area of up to 50 mm², while auxiliary field wiring requires a minimum cross-sectional area of 35 mm². Primary current can reach 800 A, and the matching transformer secondary can withstand surges of 36 kA. The water-cooling circuit requires a minimum flow rate of 4 L/min to keep semiconductor junction temperatures within their operating limits. At this flow rate, the cooling channels produce a pressure drop of only 0.1 bar. The unit meets climatic category 3K3 and can operate in control rooms at temperatures from +10 °C to +55 °C. Storage is permitted from -25 °C to +70 °C, and the unit has an approximate weight of 25 kg.
