QUICK START PROCEDURE
Figure 2. Proper Equipment Setup for DC2331A-A and DC2331A-B
• Connect the input power supply with power off,
load and meters. See the next section, Power
Connections Between Assemblies and Optional
Heatsinks, for tips on how to connect input and
output power.
16. After all connections are made, turn on the input
power and verify that the input voltage is between
14V and 56V.
17. Remove the clip-on lead that connects all the
SHDN
terminals to GND. Verify that the output voltage is 12V.
NOTE: If the output voltage is low, try startup again
using SHDN with the load disconnected. The load
may cause low output if some of the DC2331A power
sections are inadvertently disconnected and not able
to deliver power. It is possible the input supply may
current limit and cause DC2331A to have low output.
In more extreme cases it is possible that the load may
be set too high for DC2331A.
