What the UR1HH does
Converts 100-240 VAC (50/60 Hz) or 125-250 VDC into the internal 24 V DC bus that feeds every I/O and CPU card in a GE Multilin UR chassis.
35 W continuous output, cold-swap compatible, overload/short-circuit protected.
One UR1HH is mandatory in every rack; larger racks simply add a second unit for redundancy.
