51400712-200 is one of the original power supplies for the 10-slot chassis, used in LCN nodes. WPC refurbishes LCN power supplies replacing electrolytic capacitors and verify output voltage specs.

All our power supplies are shipped pinned for internal line frequency clock. If Sequence of Events (SOE) functionality is required on a NIM, the clock master, the clock slave, and the NIMs with SOE requirements must be pinned for use with external clocks. All other nodes are pinned for internal (line frequency) clock. The jumper is located on the printed circuit board (daughter board), and is clearly marked (INT) and (EXT).

Note:This power supply does not provide sufficient power to operate the 51401952-100 and 51201952-200 keyboard interfaces.
