Inductive Loads and Batteries
CAUTION
The XG/XTR power supply requires freewheeling and blocking diodes
across the output while driving inductive loads or batteries to protect the
power supply from damage caused by power being fed back into the
supply and from high voltage transients.
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.
