You can create your own NV350 or NV700 confi guration online at www.nv-power.com. This method checks your confi guration and
offers the optimum solution. Alternatively, you can do this manually by using the guide below. Calculate total output power to ensure
power requirements within 350W or 1150W, then select required Cooling, Connection and Controls/Signals from the following tables:
1. Confi guration Guide
Select Output Modules from the Module Tables below ensuring that
no more that 6 slots (NV-350) or 8 slots (NV-700) in total are used.
Example - if you require 5.2V 40A :-
a) Select B as closest match for voltage & current and prefi x with
voltage eg 5.2B
b) Repeat for other outputs.
This will create a complete product description eg NV3SSSES5V
5.2B 12/15DB which represents a three output NV350 with
Forward air cooling, Screw input terminals, 300μA Leakage,
ac good, PSU enable and 5V/2A aux supply
Output 1 = 5.2V / 40A
Output 2 = 12V / 13A with screw terminals
Output 3 = 15V / 4A with screw terminals
Max 350W continuous output power
Contact Lambda to validate confi guration or visit the NV
webpage to validate part number. (www.nv-power.com)
