NV350/700 Series
1. Configuration Guide
You can create your own NV350 or NV700 configuration online at www.nv-power.com. This method checks your configuration 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:

3 - The Primary Option uses 1 slot
4 - Not with NV7
1 - Thermocoupled sample recommended to ensure adequate cooling - consult sales
2 - Not with customer air cooling
2. Output Section
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 prefix 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
