5.14 SERIES OPERATION

Power supplies of the SAME MODEL can be connected in series to obtain increased output voltage.

Split connection of the power supplies gives positive and negative output voltage.

5.14.1 Series connection for increased outp

ut voltage

In this mode, two units are connected so that their outputs are summed. Set the Current of each

power supply to the maximum that the load can handle without damage. It is recommended that d

i-

odes be connected in parallel with each unit output to

prevent reverse voltage during start up s

e-

quence or in case one unit shuts down. Each diode should be rated to at least the power supply rated

Output Voltage and Output Current. Refer to Fig.5

-

1 and 5

-

2 for series operation with local and r

e-

mote sensing.

Remote programming in series operation for increased output voltage:

1. Programming by external voltage:

The analog programming circuits of this power supply

are referenced to the negative output potential. Ther

e-

fore, the circuits used to contro

l each series connected

unit must be separated and floated from each other.

2. Using the SO function and PS_OK signal: The Shut

-

Off and PS_OK circuits are referenced to the

isolated interface common, IF_COM (J1

-

2,3). The

IF_COM terminals of different units

can be connected to

obtain a single control circuit for the power supplies co

n-

nected in series.

CAUTION

Do not connected power supplies from diffe

r

ent

ma

nufacturers in series or in parallel.

WARNING

When power supplies are connected in series, and the load or one of the output

terminals is grounded, no point may be at a greater potential of +/

-

60VDC from

ground for mod

els up to 60VDC Rated Output and +/

-

600VDC from ground for

models >60VDC Rated Output. When u

s

ing RS232/RS485 or IEEE, refer to the

OUTPUT TERMINALS GROUNDING warning in Section 3.9.11.
