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 least 20% greater than the supply’s

 

output voltage and have a current 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.

 

Connecting

Proper connection of distributed loads is an important aspect of power supply use.

Multiple

Two common methods of connection are the parallel power distribution method and

Loads

the radial power distribution method.

 

 

Radial Power Distribution Method

To connect distributed loads, we

 

recommend that you use this method. With this method, you connect power to each

 

load individually from a single pair of terminals designated as the positive and

 

negative distribution terminals. This pair of terminals may be the power supply

 

output terminals, the load terminals, or a distinct set of terminals specially

 

established for distribution. In this scheme, there are no ground loops and the effect

 

of one load upon another is minimized.

 

 

Connect the remote sense leads to these terminals to compensate for losses and

 

minimize the effect of one load upon another. See “Remote Sensing” below for more

 

information about using remote sensing.

 

 

Parallel Power Distribution Method

This distribution method involves

 

connecting leads from the power supply to one load, from that load to the next load,

 

and so on for each load in the system. The voltage at each load depends on the current

 

drawn by the other loads and DC ground loops are developed. Except for low-current

 

applications, we recommend that you do not use this method.
