10) MON I TORING OUT PUTS
The mon i tor out puts give a volt age 0 - 5 V pro por tional to the out put
cur rent or volt age. The out put cur rent can eas ily be mea sured
with out an ex ter nal shunt us ing the CC mon i tor (see fig. 3 - 6).
The mon i tor out puts are buf fered by op-amp’s and pro tected by
zeners in par al lel (see fig. 3 - 7). The ta ble 3 - 1 shows the
im ped ance of the mon i tor ing out puts. The mon i tor ing and the
ref er ence out puts are sta ble for ca pac i tive loads up to 2 µF, for larger
val ues a 22 Ohm re sis tor should be put in se ries.
Note: in case of a pul sat ing load, the I mon i tor volt age will not
ex actly match the out put cur rent. This is mainly caused by the
cur rent through the out put ca pac i tors. Re mote sens ing will
worsen this ef fect.

+12V ON PRO GRAMMING CON NEC TOR
The +12V on the pro gram ming con nec tor can be used for sup ply ing
ex ter nal cir cuits like the MASTER / SLAVE ADAPTER. The out put is
cur rent lim ited, but should not be over loaded.
12) CC STATUS OUT PUT
The CC sta tus out put has an open out put volt age of 5 V and a short
cir cuit cur rent of 10 mA. This makes it pos si ble to drive di rectly: an
opto-coupler, a TTL gate or a CMOS gate.
13) RE MOTE SHUT DOWN
A volt age of +5V on the Re mote Shut Down in put on the pro gram -
ming con nec tor will switch off the power cir cuit of the unit. In standby
mode the power sup ply con sumes very lit tle power.
It is also pos si ble to use a re lay con tact or a switch to shut down the
unit: con nect a switch be tween Vref and Rem. Shutd. (pin 9 and 5).
14) PRO GRAMMING RE SPONSE TIME
The re sponse time is mea sured with a step wave form at the CV
prog. in put. The load is re sis tive. Pro gramming from a low to a high
out put volt age is nearly load in de pend ent, but pro gram ming down to
a low volt age takes more time on lighter loads. This is caused by the
out put ca pac i tors, which can only be dis charged by the load be cause
the power sup ply can not sink cur rent.
