Product Description:
The PSI63C0.783-W2 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It conditions three-phase utility power so machine controllers can drive induction heaters, resonant converters, or similar loads that require adjustable medium-frequency energy. An integrated power supply produces 24 V logic power, allowing the same unit to feed control electronics without an external supply.
The inverter accepts line voltages from 480–690 VAC at a mains frequency of 50 or 60 Hz, giving it direct compatibility with common industrial power grids. Its internal auxiliary supply delivers 24 VDC with up to 2 A of current for sensors, relays, or communication gateways. A water-cooled plate removes up to 420 W of heat from the power stage, helping maintain semiconductor junction temperatures under rated operating conditions. Power sequencing is coordinated by an Ethernet timer, which provides network-synchronized start and stop events for systems that use multiple inverters. The climatic category is 3K3 under EN 60721-3-3, indicating that the unit is intended for control rooms or enclosed machinery with moderate humidity and limited dust.
Ingress protection is rated at IP20, so the enclosure blocks accidental contact with live parts but must be installed in a suitable cabinet where dust or liquid exposure is possible. The operating temperature range of +10 to +55 °C covers many production environments, while storage and transportation are permitted between -25 °C and +70 °C. At 25 kg, the chassis requires a mounting surface and hardware capable of supporting its weight securely. Adequate clearance should be maintained for electrical connections and access to the water-cooling circuit, while the surrounding enclosure should provide the protection required for the installation area.
