Calculating Total Current Draw
The Total Current Draw must not exceed 5 Amps, or the power supply may
overheat. The XP5 has built-in current limit/thermal overload protection
and the DC output will turn off if either occurs.A better design guidline (to
prevent early power problems and extend the life of power supplies and
batteries) is to limit the calculated draw to 50-75% of Max. (2.50-3.75A),
especially when charging batteries.Also, future system expansion should
be considered in your load calculations.
Cable Resistance
When powering devices over considerable distances, cabling resistance
may be so high that the voltage available at the device has dropped to an
unacceptable level. To prevent this from occuring, system cabling should
be designed with adequate sized conductors.
Heat Buildup
A by-product of all step-down power supplies/regulators/transformers is
heat. Continuously pushing power supplies to their limits will maximize
heat dissipation and buildup within power cabinets - which will thereby
work to reduce the life of these components. Consider their location or the
use of cabinet grills or fans to reduce heat buildup.
Power Distribution
Separately fusing output devices or groups of output devices greatly
reduces trouble-shooting efforts. The larger the power supply and number
of devices powered, the greater the need for power distribution. BASE has
a variety of power distribution products that help speed installations while
providing easier maintenance and a custom professional appearance.
