Note: The
SM300-10D
needs an ex tra par al lel di ode on the
out put, with out this di ode the in ter nal di ode will still blow. For
this di ode 2 par al leled BYT261-PIV-400 from ST can be used.
The SM300-10D with op tion P023 has an ex tra di ode built-in.

RE MOTE SHUT DOWN / OVER CUR RENT TRIP
•
The Remote ShutDown can be op er ated with +5 V or a re lay
con tact (see fig. 4 - 10).
•
Using the Remote ShutDown in put, an
Over Cur rent Trip
could be made (see fig. 4 - 10).

MASTER / SLAVE SERIES OP ER A TION
•
For se ries op er a tion the
MAS TER / SLAVE SE RIES ADAP-
TER
(
δ
-prod uct)
must be used (see fig. 4 - 11).
•
First, con nect out put ter mi nals and test sys tem in
nor mal se -
ries
op er a tion. En sure that all (out put) power con nec tions are
re li able. An in ter rup tion of one of the power leads can cause a
fuse to blow in the unit, see ''trou ble shoot ing''.
•
The volt age drop in the con nect ing leads be tween the units
should be kept < 10 mV.
•
Sec ond, switch off all units. Con nect units as shown in fig. 4 -
12. Use stan dard 15 pole (1:1)
shielded ca bles
.
•
The max. num ber of slaves is only lim ited by the max. to tal volt -
age of 600 V.

MASTER / SLAVE PAR AL LEL OP ER A TION
•
Note: Mas ter / Slave par al lel is not rec om mended for more
than 4 units, con sult fac tory for us ing more than 4 power
sup plies in par al lel.
•
First con nect out put ter mi nals and test sys tem in
nor mal par al -
lel
op er a tion. En sure that all power con nec tions are re li able. An
in ter rup tion of one of the (out put) power leads can cause a fuse
to blow in the unit, see “trou ble shoot ing”.
•
Sec ond, switch off all units. Plug in prog. connectors with the
con nec tions ac cord ing to fig. 4 - 13 (buss bar to pol ogy). Al ways
use a
shielded ca ble
. The shield ing must be con nected to the
case of the supply.
Dis con nect the links be tween the S– and –
of the
slaves only
.
If not re moved the cur rent shar ing will not be pro por tional.
Both prog. switches of the slaves should be in the po si tion PRO -
GRAM.
•
The pur pose of the link be tween pin 9 and 11 is to set the volt -
age limit of the slaves at max i mum.
•
Keep the load close to the mas ter. Keep wir ing be tween mas ter
and slaves short. The volt age drop be tween a unit and the buss
bar should be kept < 10 mV.
•
Ac ci den tal in ter rup tion of a neg a tive load lead of a unit dur ing
op er a tion will cause fuse F600 to blow, see sec tion ‘trou ble
shoot ing’.
•
The S
−
and S+ could be con nected to the load if de sired, but this
is not rec om mended be cause of the com plex ity.
