To order a 100 watt, 15 V out (single output), industrial grade power supply with pins out the side,
the model number would be: NB100SI/15-A. Military grade would be NB100SM/15-A. To order a
100 watt, dual output, 15 V and 15 V, industrial grade power supply with pins out the top, the model
number would be NB100DI/15/15-C. Dual output, 12 V and 15 V, military grade, would be
NB100DM/12/15-C. When ordering a dual output unit, the first output voltage in the model number
is located on channel 1, and the second output voltage in the model number is located on channel
2 (see case drawing for details).
