Product Description:
The Bosch Rexroth Indramat PSI6100.421-L1 is a medium-frequency inverter in the PSI Frequency Inverters series. Designed for industrial automation, it converts three-phase utility power into regulated medium-frequency energy used to run induction heaters, high-frequency transformers, or specialized servo drives. By modulating voltage and current internally, the unit supports precise process control where rapid thermal or electromagnetic response is required. Its compact design allows it to be mounted in a cabinet within machine tools, forming machinery, or materials-processing equipment.
Electrically, the inverter accepts a supply range of 400–480 VAC and draws up to 110 A during nominal operation. The core electronics dissipate 69 W when the output stage is idle, and total enclosure heat rises to 170 W at maximum line current. The air-cooled architecture removes this heat through forced ventilation. The housing has an IP20 touch-safe rating, so the final installation must place the drive behind a protective panel. Discrete control terminals are absent; instead, an RS-232 interface board manages configuration and status. Internal logic is powered by a 24 VDC rail that can deliver 2 A to sensors, relays, and the built-in sequencing circuit.
High-current events are accommodated by an output limit of 400 A, with the cooling system sized for peak thermal rejection of 360 W during sustained high-load cycles. The controller can store 256 individual programs, and its command engine updates at a sequence frequency of 1000 Hz. This update rate enables precise timing for complex motion or heating profiles. The safety chain uses a stop circuit rated at 24 VDC / 3 A, and the automatic fault reset returns the inverter to service after the fault condition clears. Digital pressure feedback and an analog pressure output allow the unit to integrate into hydraulic or pneumatic closed-loop systems without additional signal converters.
