SECONDARY CONTROL - SC PIN
PARALLEL BUS - PR PIN
Output Voltage Programming
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
300 V Input
Parallel Operation
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy. 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:
to a single communication bus through 0 . 001 μ F (500 V)

AC coupled single-wire interface. All PR pins are connected
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. Up to three
converters may be paralleled by this method. See Figure 9.
Transformer coupled interface. For paralleling four or more
converters a transformer coupled interface is required. See
Figure 10.

reduced by the same percentage that output voltage is
trimmed down. Do not exceed maximum rated output current.
2. The trim down resistor must be connected between the SC
and -S pins. Do not bypass the SC pin directly with a
capacitor.
