DC power supply modules Device features 6 6.1 6.1 Device features The most important device features at a glance: ƒ DC power supply modules supply the DC buses of several controllers of a drive system with energy. ƒ DC power supply modules are the central AC mains connection in a DC-bus operation. ƒ DC power supply modules have an internal brake chopper and a terminal for a brake resistor. ƒ DC power supply modules of the 9400 series have a busbar port for the easy connection and side-by-side mounting of the 9400 controllers up to 100 A. Ports for higher currents or compatible device series are available. ƒ DC power supply modules generally supply controllers of the ”Multi Drive” version.
However, also controllers of the ”Single Drive” version can be implemented in a DC-bus operation if the data and notes in the ”DC-bus operation” chapter are observed. ƒ DC power supply modules are designed as multi-range voltage units (230/400/480/500 V). ƒ Four types of DC power supply modules are available: – E94APNE0104 , Rated current: 10 A, Device size: 1, Version: compact standard device with installation backplane – E94APNE0364 , Rated current: 36 A, Device size: 3, Version: compact standard device with installation backplane – E94APNE1004 , Rated current: 100 A, Device size: 4, Version: compact total device – E94APNE2454 , Rated current: 245 A, Device size: 5, Version:
compact total device ƒ DC power supply modules are assigned to specially designed mains filters and RFI filters. ƒ DC power supply modules and filters can be mounted in the mounting grid of the 9400 series. When drive systems are used in a DC-bus connection, the connected controllers can exchange energy on the DC voltage level (DC bus). 6.1-1 EDS94SPP101 EN 3.1-04/2007
