OUTPUT VOLTAGE CONFIGURATION
Although the output is described for negative rails, the input and output circuits are internally
isolated hence positive rails can also be generated, or a mixture of positive and negative.
The output 0V rail reference can be taken from any of the output terminals to give the range
of outputs as described in Output Voltage Configurations table below.

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 0V 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.
