External Accessories (External to MX chassis)
Input / Output wiring junction box. Connects two to six three-phase MX45
cabinet outputs, neutral and ground to a common output terminal block
housed in a metal enclosure junction box. Can also be used to connect
multiple MX chassis to common AC input service. See section
3.13
Output noise filter, 3 phase + neutral. May be used to reduce output
noise of MX30 or MX45 when testing EUT’s for conducted emissions.
This is an external filter that attenuates the 250 KHz ripple frequency on
the MX output by > 20 dB. The filter is rated for 125A per phase and 800
Hz. Fo
r multi-box configurations, one filter is required per chassis.
Connects to MX30 or MX45 three
-phase output terminal only.
Output fuse box. Provides added protection for MX system
configurations consisting of more than 2 MX cabinets. (MX135, MX180,
MX225 and MX270).
