PM2831/32
The followin
g
characteristic shows the work area of the output parameters. The
linear system power supplies PM2831 and PM2832 can source as well as sink
currents. There is, however, only one settin
g
for current. When the power supply
is used as a load, the value of the sink current will always track the positive
settin
g
.
This characteristic shows that the power supply will output maximum power (only)
at V
max
@ I
max
and will absorb maximum power at V
max
@ -I
max
.
Overcurrent protection, if enabled, will also work for sink currents that exceed I
set
.
Overvolta
g
e protection will work also for volta
g
es applied from an external source,
if the volta
g
e from this source exceeds the overvolta
g
e protection level.
