30 A.07.370e - Edition 2.0
Description
Input filter, 15 kVA small cabinet and big cabinet
The input filter is a 12.5 kHz filter that blocks the noise the
equipment produces from the line input at a different frequency
than the line filter.
3.5.3 IGBT power bridge
The IGBT power bridge has the components that follow:
„
Diode sensing PCB
„
IGBT PCB
„
IGBT
Diode sensing PCB (EPS476 / EPS507), stackable cabinet and small cabinet
The diode bridge converts the AC line input to a rectified current
and voltage.
The sensing PCB measures the AC input line.
Diode bridge, big cabinet
The diode bridge converts the AC line input to a rectified current
and voltage.
WARNING
If one of these three components breaks, you must replace the entire IGBT power bridge.
Note
In the stackable cabinet and the small cabinet, the
sensing PCB and the diode bridge are combined
into one part.
Note
In the big cabinet, the sensing PCB and the diode
bridge are separate parts.
