UPPLIES
Your 24VDC power distribution requirements will help you determine
which power supply (or supplies) and wiring harness to select. You can
integrate 1 or 2 supplies depending on your machine’s specific
requirements.
There are a few considerations to keep in mind when selecting the
24VDC supply/supplies to be used with the eF-785. The supply you
choose should, at a minimum have:
•
•
•
Internal protective fusing
A nominal voltage range of 12-41VDC
Output current not to exceed 20A Maximum

(J5)
The 24VDC supplies are connected to the 24VDC Supply connector J5
(see figure below), located on the rear panel of the eF-785. This
connector not only serves to provide two different control modes for AC
line voltage to power the supplies (described below), it also receives the
24VDC power back from the supplies for fusing and external distribution.
