Active Line Connection Modules

Заказные данные
(5)

Active Line Connection Modules comprise a Line Connection Module, a liquid-cooled Active Interface Module and a liquid-cooled Active Line Module. They can supply motoring energy to the DC link and return regenerative energy to the line supply.

As standard, the Active Line Connection Module is positioned in the drive lineup so that the Motor Modules are arranged to the right. If Motor Modules are to be arranged to the left of the Active Line Connection Module, option M88 (DC bus system for line-side Cabinet Modules) must be ordered.

Line Connection Modules contain the line-side infeed via main breaker with fuse switch disconnector or circuit breaker and establish the connection between the plant power system and the Active Line Modules. It is equipped as standard with a radio interference suppression filter according to EN 61800‑3 Category C3.

Active Line Connection Modules produce a stabilized DC voltage that remains constant regardless of fluctuations in the line voltage (the line voltage must remain within the permissible tolerances).

In the factory setting, the DC voltage is regulated to 1.5 times the rms value of the rated line voltage.

Active Line Connection Modules draw a virtually sinusoidal current from the supply system and cause virtually no line harmonics.

Active Line Connection Modules are suitable for connection to supply systems grounded at the neutral point (TN, TT) and non-grounded (IT) supply systems. The following voltages and currents are available:

Line voltage	Rated infeed/regenerative feedback current	Rated power
380 ... 480 V 3 AC	985 ... 1405 A	630 ... 900 kW
500 ... 690 V 3 AC	1025 ... 1560 A	1100 ... 1700 kW

Active Line Modules always include an Active Interface Module, which contains the associated Clean Power Filter and pre-charging circuit. The line filter that is included ensures compliance with the EMC requirements for the “second environment”.

Depending on the input current, the following versions are available:

≤ 800 A: Main circuit breaker with fuse switch disconnector
> 800 A: Circuit breaker, type 3WL, with option L25 as withdrawable circuit breaker

The power rating can be increased by connecting Active Line Connection Modules in parallel. You must observe the following rules:

Up to four identical Active Line Connection Modules can be connected in parallel.
A common Control Unit is required whenever the modules are connected in parallel.
The parallel connection must be supplied from a common infeed point (i.e. the modules cannot be operated on different line supplies).
A derating factor of 5% must be taken into consideration, regardless of the number of modules connected in parallel.
The main contactors or circuit breakers of the respective Line Connection Modules must close together and simultaneously. Monitoring is performed via the -X50 terminals of the respective Line Connection Module.
Option M88 must be ordered.
