TET Electronics ARGOS-1200 - Parallel Operation

10. Parallel operation
If higher output currents are required it is possible to have the ARGOS power supplies operate in a
parallel manner.
10.1 Simple output load terminals connection
Please note the following :
In order to get an even load current distribution, both ARGOS power supplies have to be
adjusted to the same output voltage prior to connecting the output load terminals. The
connecting cables should be as short as possible and with corresponding cross section.
Because it is not possible to ensure a simultaneously switch off of the devices in case of an over
voltage, decoupling diodes should be used. In that case a sensing compensation is not possible
(see also point 8).
If an accurate regulation in necessary an Auto-Load-Share Parelling operation is to be
configured (point 10.2).
10.2 Auto-Load-Share Paralleling Operation
(only possible with supplies of same voltage and current range)
