Product Description:
The PSI62C0.660-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat and belongs to the PSI Frequency Inverters series. This cabinet-style unit converts three-phase line power into controlled medium-frequency current for induction coils or transformers used in automated heating, brazing, and hardening cells. By integrating a DeviceNet I/O bus, the inverter exchanges real-time setpoints and status with higher-level PLCs so that process parameters stay coordinated with line speed and material flow. Its enclosure format also suits fixed installation in production systems where power conversion and process control must operate together.
Electrically, the inverter accepts an input range of 400–480 VAC and uses an internal carrier frequency of 1 kHz to shape the switched output waveform. All logic circuits are powered by a separate 24 V DC control supply, which isolates command electronics from the high-energy power stage. During peak demand, the stack can deliver up to 1200 A of output current, and the enclosure has an IP20 rating for protection against accidental contact and small solid objects. Eight parallel inputs and eight parallel outputs, together with 9-byte DeviceNet input and 9-byte output data fields, give the drive both hardwired and networked interfacing for automation signals.
Thermal management uses a closed water circuit, and a flow of 4 L/min keeps the heat sink temperature stable as long as the inlet temperature stays at or below 30 °C. Under continuous operation, the liquid removes up to 700 W of cooling loss plus the basic cabinet loss of 69 W, which supports operation at the nominal system current of 220 A. The M16 × 1.5 threaded ports simplify connection to plant manifolds, and the inverter’s network-accessible timers support coordinated energy dosing during synchronized process sequences. Closed-loop liquid cooling also moves heat away from the power section without relying only on cabinet airflow.
