* Pin style designator follows the “B” after the output power and precedes the baseplate designator.
CONTROL FUNCTIONS - PR PIN
Parallel Operation
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.
Compatible interface architectures include the following:
DC coupled single-wire interface. All PR pins are directly
connected to one another. This interface supports current

the same electric potential. See Figure 9.
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.
• This module is designed for point of load regulation, where remote sensing
is not required. Active voltage drop compensator, as shown here, may be
used in applications with significant distribution losses. Details of this circuit
are available in the design guide.
