Product Description:
The PSI65C0.632-W1 is produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It is a medium-frequency inverter that converts three-phase plant power into a controllable intermediate-frequency supply for induction heaters, bonding stations, and other automated assemblies that demand stable, rapidly adjustable energy. By performing this conversion electronically, the unit gives a machine controller direct control over process temperature and power density without relying on mechanical contactors. This electronic control also supports rapid power adjustments as operating conditions change during an automated production cycle.
The inverter connects to factory mains rated at 400 to 480 VAC and accepts network frequencies of 50/60 Hz, so it can be installed on many industrial grids without transformers. Heat produced by the switching elements is removed through a water-cooled plate, and the residual thermal load transferred to the cooling circuit is limited to 420 W. All electronics are housed in an enclosure rated at IP20. This degree of protection prevents accidental finger contact with live parts when the cabinet door is open, but the inverter still requires a separate enclosure in dusty or wet areas. A DeviceNet-based timer module coordinates internal gating with external control signals. The assembly weighs approximately 25 kg, which supports stable panel mounting without making the unit excessively difficult to position.
An integrated auxiliary supply delivers 24 VDC at a maximum current of 2 A, allowing drives, sensors, or safety relays in the same cabinet to share a regulated control voltage. The inverter has a 3K3 climatic class, indicating suitability for industrial rooms with moderate humidity and limited airborne contaminants. Continuous operation is permitted from +10 to +55 °C, while storage and transportation are allowed from −25 °C to +70 °C without performance loss. The regulated auxiliary output can reduce the need for a separate control-voltage source when connected devices remain within the available current limit.
