5.6.1 Parallel connection of output channels
Note: For the PM2812 and PM2813 you can face a number of restrictions
when connectin
g
output channels in parallel to a load. Please read
Appendix D to
g
et more information of parallel connection of output
channels fore these instruments.
For the PM2831 and PM2832, parallel connection of output channels is
only possible in the source (non-sink) mode
Connectin
g
output channels in parallel provides a
g
reater current capability than
can be obtained from a sin
g
le output channel. In principle, you can put more than
two output channels in parallel.
Output channels in parallel confi
g
urations can operate in either Constant Volta
g
e
(CV) or in Constant Current (CC).
When channels are connected in parallel with the intention of increasin
g
the
current capability, it is advised that you set all channels to the same volta
g
e. When
the channels have the same power characteristics, set them to the same current
value.
In
g
eneral, you can handle the followin
g
procedure.
• Set the power supply to STANDBY before makin
g
any connections.
• Connect the channels in parallel.
If a constant volta
g
e is required accross the load, proceed as follows.
