Description

Air-cooled Active Interface Modules are used in conjunction with liquid-cooled Active Line
Modules in chassis format. The air-cooled Active Interface Modules contain a Clean Power
Filter with basic RI suppression, the pre-charging circuit for the Active Line Module, the line
voltage sensing circuit and monitoring sensors.
Frame size GI is equipped as standard with a bypass contactor which ensures a highly
compact design. The bypass contactor must be provided separately for frame size HI.
The vast majority of line harmonics are suppressed by the Clean Power Filter.
The Active Interface Module contains:
● Clean Power Filter
● Line reactor
● Pre-charging circuit
● Bypass contactor (for frame size GI)
● Line voltage sensing module VSM10
● Fan
