4.2 Chokes
The chokes (inductances or coils) are used with regenerative power supplies
(XPS-25 and XPS-65) and regenerative regulated power supplies
(RPS-80, RPS-75, RPS-45 and RPS-20).
When returning power to mains, the impedance of mains for the outgoing
currents is very low. Hence, the up ramps of this current must be limited
with a choke.
These three-phase chokes for XPS and RPS power supplies must be
connected to the power line input.
On the XPS power supplies, the choke must be connected to power terminals
CH1 and CH2 located at the bottom of the module.
RPS power supplies do not have connection terminals at the bottom of
the module like at XPS power supplies; therefore, it must be connected to
the power line between the MAINS FILTER A and the RPS power
supply itself. See diagrams in the corresponding chapter of this manual.
The internal switching mechanism of these power supplies generates a
regenerative current to mains already filtered by this choke.
FAGOR provides the XPS-25 and XPS-65-A chokes that must necessarily
go with the corresponding XPS power supplies and the RPS-75-3, RPS-45
and RPS-20 chokes that must go with RPS power supplies.
