Inductive Loads
To prevent damage to the power supply from inductive kickback, connect
a diode across the output. The diode must have a voltage rating at least
20% greater than the power supply's output voltage and have a current
rating greater than or equal to the power supply's output rating. Connect
the cathode to the positive output and the anode to the return.
Where positive load transients such as back EMF from a motor may
occur, connect a Transient Voltage Suppressor (TVS) or a varistor across
the output to protect the power supply. The breakdown voltage rating for
the TVS or varistor must be approximately 10% higher than the rated
supply output.
Connecting Single Loads
Figure 2-2 shows the recommended load connections for a single load
which is sensing its voltage locally. Local sense lines shown are the
default connections at the rear panel APG J1 connector (see Figure 4-1 on
page 4–5). The load lines should use the largest gauge and shortest length
of wire possible to ensure optimal performance.
You do not need remote sensing for basic operation of your power supply.
However, if you wish to correct any small drops in your load lines, then
use the remote sensing feature. See “Step 7: Connecting Remote Sensing”
on page 2–13 for more information.
