Product Description:
The PSI61C0.100-L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. Designed for industrial automation tasks that require controlled medium-frequency power, the unit converts fixed three-phase mains power into a regulated output suitable for inductive heating generators, spindle drives, or similar loads that benefit from variable-frequency operation. By placing the inverter between the mains supply and the application, a facility can achieve precise energy delivery and reduce mechanical stress compared with traditional line-powered solutions.
The inverter accepts a three-phase input ranging from 400 to 480 VAC and can be synchronized with plant grids operating at 50 or 60 Hz. An internal auxiliary power stage delivers 24 VDC at up to 2 A, so external control electronics and the timer circuit receive a stable low-voltage supply without separate power supplies. The enclosure has a protection rating of IP20, meaning live parts are shielded from touch, but the unit must be installed inside a suitable cabinet. Forced air moves through the heat sink because the unit is air-cooled. Its 3K3 climatic classification under EN 60721-3-3 indicates that the device is suitable for clean, ventilated production areas.
Heat dissipation can reach 360 W, which must be considered when cabinet ventilation is selected. During operation, the electronics remain stable within an ambient temperature range of +10 to +55 °C. Storage and transportation are permitted at temperatures from -25 to +70 °C, allowing the inverter to be kept in unconditioned facilities within this range. The inverter weighs 20 kg, providing a substantial housing that supports secure cabinet mounting and continuous operation. Adequate mounting support should be used to carry this weight, and sufficient clearance around the cooling passages should be maintained to prevent restricted airflow. The cabinet layout should also allow heated air to leave the enclosure without recirculating through the inverter’s intake path.
