Active Interface Modules Chassis-2

Description

Active Interface Modules Chassis-2 contain a Clean Power Filter. The filter structure permits
operation with higher pulse frequencies, which in turn allows line harmonics to be reduced
even further; additional information on this topic is available on request.
Basic RI suppression, line voltage sensing and temperature monitoring sensors are also
included.
The precharging input circuit that is necessary for operation, comprised of resistors, a
precharging contactor and a main contactor, must be provided separately. The precharging
contactor is controlled 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
