DC Output Current Specifications
The combined output power of all outputs will not exceed 450W. Each output has a maximum and minimum
current rating, as shown in Table 3-4. 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.
