CONTROL FUNCTIONS - PR PIN  
Parallel Operation  
sharing but is not fault tolerant. Minus In pins must be tied to  
the same electric potential. See Figure 9.  
The PR pin supports paralleling for increased power with N+1  
(N+M) redundancy and phased array capability. Modules of  
the same input voltage, output voltage, and power level will  
current share if all PR pins are suitably interfaced.  
AC coupled single-wire interface. All PR pins are connected to  
a single communication bus through 0.001µF (500V)  
capacitors. This interface supports current sharing and is fault  
tolerant except for the communication bus. See Figure 10.  
Compatible interface architectures include the following:  
DC coupled single-wire interface. All PR pins are directly  
connected to one another. This interface supports current
