Product Description:
The PSI62C0.738-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It conditions three-phase power so automation controllers can drive induction heaters, high-speed spindles, and other loads that require adjustable medium-frequency energy. By converting plant voltage to a controlled output, the unit gives production machines precise power modulation without bulky mechanical transformers. This capability supports stable and repeatable industrial processes that depend on controlled power delivery.
Electrical compatibility begins with a three-phase input range of 400 to 480 VAC, allowing the inverter to connect directly to standard factory supplies. Internally, it synchronizes with 50 or 60 Hz mains power without additional line conditioning. Heat generated by the switching devices is removed through a water-cooled circuit, and the heat exchanger accommodates up to 420 W of cooling losses. Because the housing carries an IP20 rating, it must be installed in an enclosed panel that provides appropriate protection against contact. The built-in EtherNet timer coordinates firing sequences with external controllers, maintaining accurate phase relationships under dynamic load changes.
Support electronics can be powered from the inverter because an integrated supply delivers 24 VDC at up to 2 A for sensors, contactors, or fieldbus nodes. The unit complies with the 3K3 class of EN 60721-3-3, making it suitable for switch cabinets exposed to moderate dust and controlled humidity. Its operating temperature range extends from +10 °C to +55 °C, while storage is permitted from -25 °C to +70 °C. These storage limits allow an inactive unit to remain in an unconditioned warehouse within the stated temperature range. The inverter weighs 25 kg, so its mounting surface and fasteners must provide adequate support during installation and operation.
