Load Connection
Inductive To prevent damage to the power supply from inductive kickback, connect a diode Loads 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 Figure 2.7 and Figure 2.8 show recommended load and sensing connections for Single Loads single loads. Local sense lines shown are default connections at the rear panel J10
sense connector as identified on Figure 1.2, on page 19.
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 53 for more information.
