The output voltage of the 24-VDC output will vary with the current consumption
of the load as shown in the following table. Be sure to check the current con-
sumption and allowable voltage ranges of the devices connected before using
these terminals.

ating voltage of the connected device is 26.4 V (24 V +10%).
