Product Description:
The PSI6200.100-W1 medium-frequency inverter is built by Bosch Rexroth Indramat as a member of the PSI Frequency Inverters series. Intended for induction heating, forging, or welding systems, it transforms line power into a controllable medium-frequency output. This output allows energy delivered to coils or transformer secondaries to be adjusted without mechanical switching equipment. Electronic power control supports repeatable heating and welding cycles in automated production cells while allowing the connected control system to regulate the process.
Operating from a three-phase input of 400–480 VAC, the inverter’s power section switches the waveform at 1 kHz and reconstructs the required medium-frequency signal. Internal electronics use a 24 V DC control supply, which also powers the 24 V timer circuit. Continuous output reaches a nominal 220 A, while transient demand can reach 1200 A at the output terminals. A water-cooled heat sink manages thermal loading with a flow rate of 4 liters per minute and an inlet temperature no higher than 30 °C. Cooling water passes through an M16 × 1.5 threaded manifold. The enclosure has an IP20 rating and can operate in rooms with ambient temperatures up to 55 °C. The power studs accommodate copper conductors with a cross-sectional area of up to 95 mm².
Total cabinet heat dissipation is 69 W while the inverter is idling and 210 W while it is operating at maximum power. The cooling loop can remove 700 W, helping internal components remain within their thermal limits during operation. Installation is permitted at elevations up to 2000 m above sea level without output derating. The water circuit tolerates pressure drops associated with the required flow rate, allowing coolant to pass through the heat sink and return to the external cooling system. The secondary side of a compatible transformer can draw up to 54 kA, supporting high-current industrial heating or welding loads. The specified supply range, coolant temperature, and ambient temperature must be maintained to support continuous operation within the inverter’s electrical and thermal limits.
