Input / Output Specs & Power Derating

Because this PSU is engineered for global enterprise grids, its output wattage depends heavily on the input voltage ($V_{AC}$ or $V_{DC}$) of the datacenter rack:

1. Input Ratings

• AC Input Voltage: 100–240 $V_{AC}$ (Auto-Sensing)

• AC Input Current: 12A (at lower range) / 10A (at higher range)

• Frequency: 50 / 60 Hz

• DC Input Voltage: 200 $V_{DC}$

• DC Input Current: 10A

2. Output & Wattage Matrix

Depending on the electrical environment, the power output scales as follows:

• At 200–240 $V_{AC}$ Grid (High-Line AC):

  • Max Output Power: $1925\text{ W}$

  • Main Rails: $+12.3\text{ V}$ @ $150.7\text{ A}$ Max

  • Standby Rail: $+12.0\text{ Vcs}$ @ $6.0\text{ A}$ Max

• At 200 $V_{DC}$ Grid (DC High-Line):

  • Max Output Power: $1400\text{ W}$

  • Main Rails: $+12.3\text{ V}$ @ $107.82\text{ A}$ Max

  • Standby Rail: $+12.0\text{ Vcs}$ @ $6.0\text{ A}$ Max

• At 100–127 $V_{AC}$ Grid (Low-Line AC):

  • Max Output Power: $1025\text{ W}$ (De-rated)

  • Main Rails: $+12.3\text{ V}$ @ $77.48\text{ A}$ Max

  • Standby Rail: $+12.0\text{ Vcs}$ @ $6.0\text{ A}$ Max
