Connecting Outputs in Parallel
WARNING
Only connect output modules in parallel that have identical model
numbers and options
Output channels can be paralleled to obtain increased output current.
There are two ways to implement this: direct-parallel and auto-parallel.
Parallel Method Description Connections
Direct-Parallel
Recommended for SAS
and Table modes. Provides
simple, direct connections
Up to four output channels (modules)
connected in parallel. Each output
channel must be programmed
individually to source or query its share
of output current.
Parallel output terminals
together. Parallel sense terminals
together when remote sensing.
Auto-Parallel
Recommended for Fixed
mode operation. Ensures
that the output current of
the paralleled modules is
accurately matched
Up to four output channels (modules)
connected in parallel. The programmed
current value is directed only to the
output referred to as the “master”
output. This output must be channel 1
in one of the mainframes. All other
paralleled outputs, referred to as
“follower” outputs, track the output
current of the master output.
Parallel output terminals
together. Parallel sense terminals
together when remote sensing.
Connect the current
programming analog connector
pins for auto parallel operation.
Direct-Parallel Connections
NOTE
For the firmware to correctly control the paralleled output channels,
you must specify that the output channels are connected in direct-
parallel.
Refer to chapter 4 under “Configuring Paralleled Outputs”.
Direct-Parallel in SAS and Table mode
This is the simplest way to implement parallel connections. In most
cases, outputs can be connected in direct-parallel mode as shown in the
following figures without any master/follower distinction, and without
any wiring to the analog connectors. This is possible because of the
relatively high output impedance of each output channel when operating
in SAS and Table modes. This method also provides better current
programming accuracy with paralleled outputs.
In SAS and Table mode, each output must be programmed with identical
I-V curve or table data. With Lists, each output must receive the same
list. The trigger signals used to change list steps must be received at the
same time. Remote sensing may be employed on all outputs if desired,
but in many cases will have only a minimal effect on performance due to
the high output impedance of each output.
The following figure shows four outputs connected directly to the load.
