Product Description:
The PSI62C0.739-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat as part of the PSI Frequency Inverters series. Designed for integration into automated induction heating or surface-treatment lines, the unit changes three-phase mains power into a regulated, high-frequency output that can be synchronized with motion or temperature controllers. By supplying stable energy to work coils while responding to network commands, it serves as a core element in industrial automation cells that depend on precise thermal profiles. This operating role helps the process maintain repeatable heating behavior when production demand changes during a cycle.
Closed-loop regulation is anchored by a control cycle of 1 ms, executed on a TriCore processor that handles real-time tasks and floating-point power calculations. Command and diagnostic traffic passes through an Ethernet channel, and the same bus supports the EtherNet timer function that coordinates 256 selectable programs. The inverter modulates an output frequency up to 1 kHz from a mains range of 400–480 VAC at 50/60 Hz. Under nominal conditions it draws 220 A, while its input stage withstands peak primary currents up to 1200 A. A secondary crest current of 54 kA accelerates heating cycles, the 24 VDC auxiliary supply delivers 2 A for control devices, and a 95 mm² conductor cross-section is used for the high-current feed. This arrangement allows the unit to shift between stored process settings without interrupting surrounding machine control.
Thermal management relies on a water-cooled heat sink that must receive at least 4 l/min of flow and can tolerate pressures up to 10 bar. By extracting heat directly from the IGBT modules, the liquid circuit limits internal temperature rise and supports continuous medium-frequency operation while the cabinet retains the specified IP20 ingress rating. Stable coolant flow helps the power stage remain responsive during extended heating runs. The unit is therefore suited for installation in a protected enclosure where liquid cooling can remove heat from the power section without relying on forced air alone.
