The 6SN1146-1BB01-0BA1 from Siemens represents a regenerative infeed module with versatile capabilities. Designed for continuous power delivery, it maintains a standard rating of 16 kW, while briefly handling peaks up to 21 kW. In terms of maximum power provision, it can output up to 35 kW when supplied with a 400V input.

This device can operate effectively between 600/625 V when regulated and in unregulated mode from 490 to 680 V. Its working frequency lies in the range of 50 to 60 Hz, with an allowance for ±10%. For nominal current ratings at 400V, the sinewave configuration is rated at 27 A, and for squarewave operation, it reaches 30 A. It can handle up to 33 A when operating with an unregulated input.

The cooling mechanism relies on forced air via an external fan, necessitating a minimum airflow of 56 m³/h to ensure optimal thermal regulation. In configurations requiring this external cooling, the power dissipation is around 270 W, which is critical for maintaining efficiency. Notably, the regenerative module boasts an impressive energy conversion efficiency of 97%, indicating minimal energy loss during operation.

Physical dimensions include a width of 100 mm and a weight that approximates 10.5 kg, allowing for efficient installation in various setups. This module is particularly suited for applications that demand high efficiency in energy recovery and conversion.
