MX2020 High-Voltage Universal Power Supply Module LEDs
Each high-voltage second-generation universal (HVAC/HVDC) PSM faceplate contains four LEDs. These LEDs are shown in Figure 1 and Table 1. Eighteen bicolor LEDs labeled 0 through 8 for the bottom nine PSMs, and 9 through 17 for the top nine PSMs, are located in the center of the craft interface.
The primary input of the PSM is a dual redundant feed, INP0 and INP1. Both feeds are active during operation, and both feeds share load current when present. In addition, a PSM failure triggers the alarm LED on the craft interface.

INP0 (V) AC or DC within range | INP1 (V) AC or DC within range | Dip 0 | Dip 1 | PSM Switch | INP0 LED | INP1 LED | PWR OK LED | FAULT LED | PWR OK | 52V out | 5V out |
