EM.6 CHOKE FOR AN "XPS" POWER SUPPLY
When returning power to Mains, the impedance of Mains for the outgoing current is very low.
Thus, the up ramps of this current must be limited with a choke.
This choke is installed in the circuit in series with the returning line from the power bus to
mains. To do this, it must be connected to the bottom power terminals of the XPS.
The internal switching mechanism of the XPS generates a regenerative current to Mains
which is filtered by this choke.
Fagor supplies the chokes that the XPS power supplies necessarily come with.
The following table shows the characteristics of these chokes.
The last section of this chapter describes the mechanical dimensions.
The use of these Chokes IS A MUST for the proper operation of the XPS
regenerative power supplies.
The length of the cable joining the choke with the power supply must
never exceed 2 meters.
