29) SERIES OP ER A TION
Se ries op er a tion is al lowed up to 600 V to tal volt age. The power sup plies can
be con nected in se ries with out spe cial pre cau tions.
For eas ier con trol, Mas ter / Slave op er a tion is rec om mended (see fig. 3- 19).
By us ing the Mas ter / Slave ser ies fea ture a dual track ing power sup ply can
be made with one unit as mas ter and one as slave.
For se ries op er a tion in com bi na tion with Power Sink op tion, all units must
have a Power Sink built in side oth er wise no power can be ab sorbed.
30) PAR AL LEL OP ER A TION
Par al leling of the units has no lim i ta tions. The power sup plies can be con -
nected in par al lel with out spe cial pre cau tions. For eas ier con trol, Mas ter /
Slave op er a tion is rec om mended (see fig. 3- 19 and fig. 3 - 20).
Nor mal par al lel op er a tion of Fast Pro gram ming units can give prob lems,
each com bi na tion has to be tested first, in com bi na tion with the load !
For par al lel op er a tion in com bi na tion with Power Sink op tion, only one unit
can have a Power Sink. Re fer to Power Sink man ual for de tails and re stric -
tions.
31) MASTER / SLAVE OP ER A TION
The Mas ter / Slave fea ture makes it pos si ble to use the power sup plies as
build ing blocks to form one large unit (see fig. 3 - 20).
Mixed par al lel - se ries op er a tion is also pos si ble, to a max i mum of 600 V.
The re sult ing com bi na tion of units be haves like one power sup ply and can be
man u ally con trolled or pro grammed on the mas ter. Fig. 3 - 21 shows a com -
puter con trolled M/S par al lel com bi na tion.
Con nect the dif fer ent units with stan dard RJ45 ca bles (see fig 3 - 22), us ing
CON B and CON C on the rear side. With DIP switch 4 of switch SW1 the Par -
al lel or Se ries mode can be se lected.
The slaves will fol low the mas ter. The re sult is true cur rent or volt age shar -
ing in the par al lel or se ries mode re spec tively.
Note: Mas ter / Slave par al lel op er a tion is not rec om mended for more
than 3 units or in com bi na tion with Fast Pro gram ming op tion.
Con sult fac tory for a so lu tion.

The Mas ter / Slave com bi na tion can also
be pro grammed with the in ter faces
PSC-ETH, PSC-488 or the PSC-232

Use stan dard UTP ca bles
(RJ45) for Mas ter / Slave
op er a tion.
Mas ter unit:
Con nect CON B
to Slave1.
Slave unit:
Con nect CON C
to Mas ter.
Con nect CON B
to Slave2.
Warn ing:
Never con nect CON C
to CON C !
