Figure 2.2 - Example of diagram of a 12 pulse configuration with one rectifier unit
The UR11 can be provided together with the complete panel (AFW-11M) or as a stand-alone product to be
assembled in a panel. For the complete panel, all the components are provided in the panel.
NOTE!
Several additional items are needed for the complete panel assembly, such as: output inverters, AC
fuses, DC link fuses for the output power units protection, circuit breaker or disconnect switch at the
input and in case of 12 pulse configuration is also necessary to provide a phase shifting transformer.
The UR11 has an interface board feed by a +24 Vcc external power supply. This board presents three output
relays for alarm and fault indication, five LEDs for fault visualization, as well as the rectifier bridges status. There
are also two DIP switches for the voltage settings of the UR11 power supply, according to the model (refer to
item 3.4.6.4 Control Connections on page 3-18
heatsink temperature monitoring.
Figure 2.3 on page 2-6
shows a simplified block diagram of the UR11.
