numbers for triple
output.
Maximum
current as stated in
chart.

Total Output Power
Single (S), Triple (T) Output
Industrial (I) or Military (M)
Model Numbering Example:
To order a 150 watt, 15 V out (single output), industrial grade power supply with pins out the bottom, the
model number would be: NB150SI/15-B. Military grade would be NB150SM/15-B. To order a 150 watt, triple
output, 15 Vdc, 15 Vdc and 5.2 Vdc, industrial grade power supply with pins out the top, the model number
would be NB150TI/15/15/5.2-C. Triple output, 5 V, 12 V and 15 V, military grade, would be
NB150TM/5/12/15-C. When ordering a triple output unit, the first output voltage in the model number is
located on channel 1, the second output voltage in the model number is located on channel 2, and the third
output voltage in the model number is located on channel 3 (see case drawing for details).
