OUTPUT VOLTAGE CONFIGURATION
Although the output is described for negative rails, the input and output circuits are iternally isolated hence positive rails can also be generated, or a mixture of positive
and negative. The output +V
OUT rail reference can be taken from any of the output terminals to give the range of outputs as described in the Output Voltage Configura-
tions table below.

OUT2 -48V -24V OV +24V

OUT3 -72V -48V -24V OV
POWER SHARING
The 3W total power delivery can be taken from either a single channel, or from any combination of all three channels. This allows an enormous amount of flexibility,
especially when combined with the selectable output OV reference. For example, using the option 2 output configuration; -24V at 0.5W, +24V at 1W and +48V at 1.5W
power supplies are available from a single NMT device.
