Inductive

Loads

Use the following protection methods only when using local sensing.

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 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.
