Product Description:
The PSI63C0.132-W2 belongs to the PSI Frequency Inverters series manufactured by Bosch Rexroth Indramat. As a medium-frequency inverter, it converts three-phase supply power into a controlled output for induction generators, resonant converters, and other automation loads that operate at elevated switching rates. A 24 V DC logic feed supports its integration into control racks, while an MOV-based overvoltage arrestor protects connected equipment from switching transients. The inverter is intended for installations that require controlled high-frequency power within an industrial control system.
The power stage accepts a line voltage of 480–690 VAC at either 50 or 60 Hz and supports a nominal system current of 110 A. During fast load changes, the current can peak at 800 A. A secondary circuit rated for 36 kA supplies high-frequency current to the work coil and is synchronized by a control oscillator operating at 1 kHz. Cabinet heat dissipation is limited to 100 W, while an external heat exchanger removes another 500 W from the system. The internal design accommodates up to 420 W of cooling losses before derating is required. The inverter has an IP20 enclosure and meets climatic class 3K3 under EN 60721-3-3, making it suitable for lightly conditioned switchgear rooms. An auxiliary 24 V DC supply on the logic board provides 2 A for contactors and the timer circuit, allowing the inverter to power its interlocks without a separate supply.
A water-cooled baseplate transfers process heat into a closed cooling loop. The loop must provide a flow rate of 4 l/min through an M16 × 1.5 threaded connection, and the inlet temperature must not exceed 30 °C to keep semiconductor junction temperatures within operating limits. The inverter operates in ambient temperatures from +10 °C to +55 °C and may be stored between -25 °C and +70 °C without performance loss. Its dry mass is 25 kg, which must be considered when selecting mounting hardware and cabinet supports. Incoming power wiring connects to terminals that accept conductors with a maximum cross-sectional area of 50 mm². The water connection and power terminals should remain accessible so that cooling and electrical connections can be routed without placing unnecessary strain on the assembly.
