Operation 39
25A Switch Mode Rectifier  NT5C06B / C Installation and User Manual
Output current: one rectifier 25 A
two rectifiers 50 A
three rectifiers 75 A
Note that when three phase 208 / 240 V AC lines are used to power more
than one shelf, it is preferable to distribute the shelves equally among the
phases.
Use a 20 A breaker or FRN type fuse for individual AC.
Use a 40 A breaker or FRN type fuse for two rectifiers, common AC.
Use a 60 A breaker or FRN type fuse for three rectifiers, common AC.
When using the MPR15 rectifier powered from 120 V AC, the power shelf
equipped with one, two, or three rectifiers has the following specifications:
Condition: Typical input current value for 54 V dc, full load
output.( ) = maximum input current at Output 54 V dc, current limit
minimum line
