2.5.1 PW 21x, PW 110(B), PW 120 Braking Resistors

April 2007
The PW braking resistors convert
the energy fed back into the dc-link
during braking into heat.
The PW 110(B) and PW 120 have a
cooling fan, the PW 21x cools only
through heat radiation.
Either one PW x10(B) or two
PW 120 switched in series can be
connected to the UE 2xx compact
inverters.
Either one PW 21x, one PW 1x0(B),
two PW 210 in parallel or two PW
110 B in parallel can be connected to
the UE 2xx B compact inverters and
UV 130 power supply unit.
