Vision Trunk Power Hub for dSCR Systems (124412)

Not yet reviewed
Product Code: EV5-1855

The EV5-1855 IRS Trunk Power Hub is designed to used as power injector where the system requires additional current to supply additional switches in the system. The Trunk Power Hub provides a means of injecting 18VDC In two directions with DC isolation to prevent the two power supplies conflicting with each other.
