Product Description:
The PSI6200.640-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In induction hardening, melting, or other processes that require variable medium-frequency power, it converts fixed factory mains power into a regulated output while keeping switching losses low. Within an automation cell, the unit functions as the power stage and supplies controlled current to resonant heating circuits under commands from supervisory motion or process controllers. This arrangement allows the process controller to regulate delivered energy according to the operating requirements of the connected equipment.
Operating power is drawn from 400–480 VAC three-phase lines at 50 or 60 Hz, and the input bus has a nominal system current of 220 A. Peak demands, such as rapid energy delivery, can be covered up to 1200 A before the drive returns to steady-state operation. The internal IGBT bridge uses pulse-width modulation at 1 kHz, balancing switching losses with output control. A 24 VDC control supply powers the logic boards, while the integrated auxiliary supply delivers 24 V at 2 A for sensors and relays. Cabinet heat dissipation is 69 W during standby and may rise to 210 W at rated load. A separate cooler removes 700 W, with another 420 W allocated to secondary heat paths. The terminals accept power cables with conductor cross sections up to 95 mm², and a DeviceNet timer supports network-based sequencing.
Thermal management relies on a water-cooled heat exchanger that requires a flow rate of 4 L/min through an M16 × 1.5 connection, with inlet water maintained below 30 °C. The enclosure has an IP20 rating, meets climatic class 3K3, and withstands humidity class F without condensation. The inverter operates at ambient temperatures from 10 °C to 55 °C and can be stored at temperatures from -25 °C to 70 °C. It maintains full output at elevations up to 2,000 m. The maximum ambient temperature and installation altitude should be considered when selecting the coolant flow and external chiller capacity. The inverter weighs 25 kg, allowing installation in standard frames without additional lifting fixtures.
