Product Description:
Bosch Rexroth Indramat manufactures the PSI6300.105-L2 medium frequency inverter within the PSI Frequency Inverters series. Engineered for induction heating and hardening equipment, the unit converts plant mains into a controlled medium-frequency output that can be modulated for temperature-critical processes. Acting as the interface between the facility supply and the work coil, it provides precise energy delivery for automated metallurgical lines. This arrangement helps the power stage respond quickly to process changes while keeping output consistent during repeated heating cycles.
The inverter accepts a three-phase input range of 480 – 690 VAC, matching common high-voltage industrial networks. Internal circuitry is powered from a separate 24 V DC control supply that isolates the logic section from the power stage. It can deliver a peak output of 800 A, while continuous duty is limited to 110 A. The higher peak current supports brief heavy-demand periods, while the continuous rating suits longer heating runs. Up to 360 W of thermal loss is removed through an air-cooled heat sink and fan assembly. Main bus and load terminals accommodate lugs up to 50 mm², and auxiliary wiring accepts conductors up to 35 mm². Overvoltage transients are clamped by MOV devices, and the assembly weighs 21 kg, which is suitable for panel installation.
The transistor bridge is driven at a carrier frequency of 1 kHz, producing the medium-frequency waveform required by induction coils and minimizing stray heating in adjacent conductors. Operation is permitted at ambient temperatures up to 55 °C, so enclosure airflow must keep the unit within that limit. In fault conditions, the secondary circuit can withstand 36 kA when paired with a PSG 3100 transformer, which supports selective trip coordination. The housing has an IP 20 rating that guards against finger contact and requires installation in a clean cabinet. Program capacity extends to 256 steps, and a 24 V timer interface allows simple sequence control when only basic timed operation is needed.
