DC Input Voltage Specification
The power supply will operate within all specified limits over the input voltage range outlined in
Table 8. The power supply will power-off if the DC input is less than -34 VDC.

DC Output Current Specifications
The combined output power of all outputs will not exceed 450 W. Each output has a maximum and
minimum current rating, as shown in Table 9. The power supply meets both static and dynamic
voltage regulation requirements for the minimum dynamic loading conditions. The power supply
meets only the static load voltage regulation requirements for the minimum static load conditions.
