Inductive Loads
To prevent damage to the power supply from inductive kickback, connect
a diode across the output. The diode must be rated at greater than or equal
to the supply’s output voltage and have a current surge rating greater than
or equal to the supply’s output rating. Connect the cathode to the positive
output and the anode to the negative output/return.
Where positive load transients such as back EMF from a motor may
occur, connect a transorb or a varistor across the output to protect the
power supply. The breakdown voltage rating for the transorb or varistor
must be approximately 10% higher than the rated supply output.
Connecting Single Loads
Figure 2-7 and Figure 2-8 show recommended load and sensing
connections for single loads. Local sense lines shown are default
connections at the rear panel J10 sense connector as identified on Figure
1-2 on page 1–5.
You do not need remote sensing for basic operation of your supply.
However, if you wish to correct any small drops in your load lines, then
use the remote sensing feature. See “Local and Remote Sensing” on
page 2–21 for more information.
