In the AC-DC linear multi output power supplies there is the DP series.
DP Linear Power Supplies series are built in single or double output version. Two of the main features are low output ripple and slew rate. Thanks to its performance, the DP series Power Supplies can be used in laboratory both as a power source and as an amplifier.
In “dual version”, with the Master / Slave command you get two
outputs isolated from each other with the possibility of varying the
ratio between the two sections. In fact, a special trimmer allows
you to adjust the output voltage of the Slave section between 50%
and 100% of Master voltage.
