Local Power Source<br />
When a centralized power source is not available or makes no economic sense, a suitable<br />
24 or 48-volt power supply can be locally installed in your Customer Interface Box and<br />
powered from a suitable AC source, as illustrated in Figure 5, to power your <strong>SONAbeam</strong><br />
terminal.<br />
WARNING!<br />
The local power source you select must be able to provide the required power<br />
over the entire temperature range of its operating environment!<br />
NOTE…<br />
A power supply that employs AC Power Factor Correction is recommended…<br />
