Description

Active Interface Modules Chassis-2 are used in conjunction with the Active Line Modules
Chassis-2. The Active Interface Modules Chassis-2 contain a Clean Power Filter with basic
RI suppression, line voltage sensing circuit and monitoring sensors.
The pre-charging input circuit that is necessary for operation, comprised of resistors, a pre-
charge contactor and a main contactor, must be provided separately. The pre-charge
contactor is activated from the Active Line Module Chassis-2.
The vast majority of line harmonics are suppressed by the Clean Power Filter.
The Active Interface Module contains:
● Clean Power Filter
● Line reactor
● Voltage Sensing Module VSM10
● Fan
