2.4.3 SERIES OPERATION
HSF power supplies may be connected in series to obtain higher output voltages. Series config-
urations can only be accomplished by external wiring of the I/O mating connector. Blocking
diodes are incorporated in the HSF power supplies. V+ of one supply must be connected to V–
of the next supply at the DC OUTPUT terminal block.
DIP switches (positions 1 through 5) between series-connected supplies and at both ends of the
series-connected group must be set to OFF (open). Sensing can be either local or remote
(PAR. 2.4.1.3). Local sensing requires external wiring (PAR.2.4.1.2). Figure 2-11 illustrates
PS5, PS6, and PS7 connected in series.
