Active Line Modules including Active Interface Modules
Обзор
Active Line Modules can supply energy and return regenerative energy to the supply system.
In contrast to Basic Line Modules and Smart Line Modules, Active Line Modules generate a controlled DC voltage that is kept constant despite fluctuations in the line voltage (the line voltage must remain within the permissible tolerance range). Active Line Modules draw a virtually sinusoidal current from the supply system and therefore do not cause any harmful current harmonics.
Braking Modules and braking resistors are required only if the drives need to be decelerated in a controlled manner after a power failure – i.e. when energy cannot be regenerated into the line supply.
Active Line Modules are available for the following voltages and power ratings:
Line voltage | Rated power |
|---|---|
80 … 480 V 3 AC | 132 … 900 kW |
500 … 690 V 3 AC | 560 … 1400 kW |
