The 51195066-100 is the newer power supply for Honeywell's 5-slot chassis (non-CE) using the original 8-pin connector (as shown), and comes from WPC with NEW electrolytic capacitors. This power supply can replace the original 51400712-100

All our power supplies, including the 51195066-100, 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, and is not marked (EXT) or (INT). For internal line frequency clock (INT), the jumper must connect E20 and E21. For external clock source (EXT), the jumper must connect E21 and E23.

WPC refurbishes LCN power supplies by replacing electrolytic capacitors and verifying output voltage specs.

Like all parts from WPC, this power supply is tested following WPC's 5-step test program.
