The external PSU must supply a voltage in range 14VDC~24VDC. The output rating
current of this external PSU must be higher than actual work load.
To ensurecompliance with UL 62638-1 standard, the evternal PSU must be UL
62368-1 or UL 60950-1 listed and its maximum operating temperature must be
equal to higher than 45℃.
The increased voltages allow cable lengths with low diameter wire cores to increase
for the reader cable or allow matching the reader specific voltage / power require-
ments.
Note: If more than one OSDP reader is connected to the RJ45 connector, the voltage drop
between panel and reader is doubled. In that case the external power supply unit
allows the readers to be powered correctly. Always check the reader input voltage
range (12V + or – x%, or Min / Max Voltage) before connecting the reader to other
voltages than the default.
