The DC power supply modules will operate from a wide variety of AC and DC
input power sources, as distributed through the Mainframe. Although the
Mainframe could be connected to either single-phase or three-phase AC power,
the modules have single-phase inputs. They are connected to the source,
through the Mainframe, either phase to neutral, or line to line, depending on the
available source voltage. The power source voltage must be within the range of
85–264VAC or 210-300VDC. The input voltage ranges are continuous, and do
not require any manual setup.
CAUTION
Exceeding the maximum rated AC/DC input voltage could result in damage to the
module.
The modules could produce full rated power down to 103.5VAC input. At lower
voltages, output power is derated to 85% at 90VAC and 75% at 85VAC. Total
aggregate output power of the Mainframe is limited to 6,000W with 200VAC or
greater input, and 3,600W at less than 200VAC input. Each module has power
factor correction (PFC) that provides linear AC input current and high power
factor, minimizing the required input apparent power.
The Mainframe distributes the input power through backplane connectors to
three groups of four slots connected in parallel. The groups are connected to
separate pair of pins in the Mainframe rear panel AC/DC input connector (one
