How To Order
Series: NB
Total Output Power: 30
Dual Output: D
Product Grade: M ("I" for Industrial)
Output Voltage: see Selection Chart
Options: see below
 

 

 

Options
A Option: Pins out side of unit.
B Option: Pins out bottom of unit.
C Option: Pins out top of unit.
D Option: Through hole inserts (STD threaded) 0.115 01A
I Option: M2.5 inserts
Model Numbering Example:
To order a 30 watt, dual output, 5 Vdc and 15 Vdc, industrial grade power supply with pins out the top, the model number would be: NB30DI/5/15-C. Dual output, 12 V and 15 V, military grade, would be NB30DM/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 in PDF File).
