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.
