Power Supply

Choose a PSU that limits its output current by design, by setting the current limit on the supply
(if this feature exists) or use fuses. Remember to derate the fuse, if mounted in an enclosure, as
the temperature will be higher than ambient. The external power supply will need to be able to
supply at least 1A.
The use of a regulated power supply with 100% short circuit protection is recommended. If
however a non-regulated power supply is used, then the maximum ripple voltage of this power
supply must not exceed 10% of the actual DC value.
