Product Description:
The PSI6300.350-L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat in the PSI Frequency Inverters series. In automated manufacturing cells, it supplies controlled medium-frequency power to induction heaters, welders, and hardening transformers while synchronizing with higher-level control equipment through the INTERBUS timer. By converting the plant's three-phase mains into a regulated output, the unit bridges the grid and the process load and supports applications that need compact cabinet integration and fast current modulation. The regulated output helps maintain repeatable heating or welding cycles when process timing has to stay consistent from one cycle to the next. That operating role suits tightly integrated production systems that combine power conversion and process sequencing in the same control architecture.
The unit accepts a three-phase input range of 400–480 VAC and draws a nominal current of 110 A through terminals sized for 50 mm² conductors. A separate 24 V DC logic rail supplies 2 A for the control electronics and fieldbus interface. This arrangement keeps the control section powered independently from the main input stage for communication and monitoring tasks. The cabinet basic loss is 69 W when idle, and cabinet loss rises to 170 W at maximum modulation; the air-cooled design can release up to 360 W to the surrounding air stream. Protection is rated IP20, so the unit must be mounted inside an electrical enclosure. Width, height, and depth are 239 mm, 448 mm, and 280 mm, and the overall mass is 20 kg.
On the power stage, the converter can supply a primary current of up to 800 A, which the internal transformer steps to a secondary pulse of 36 kA for short welding or heating intervals. This stepped output is suitable for processes that need brief, high-energy pulses at the load. These currents are modulated at a carrier frequency of 1 kHz, which suits medium-frequency induction loads while reducing core losses. Fast modulation also helps the process transformer respond quickly to control changes. The compact enclosure leaves room for airflow across the heat sinks that dissipate operating losses.
