2.2.2 Output DC Current Ranges
All outputs are within the specified limits of regulation when each output is
subjected to the conditions listed below.
Table 3. DC Input Line Requirements
DC Nominal Voltage
Minimum
Current
Maximum
Current
+12 V DC 1.2 A 15A
+5 V DC 2.4 A 30A
+3.3 V DC 0.1 A 20A
- 12 V DC 0.0 A 0.8A
+5 V SB 0.1 A 2.0A
NOTE:
1)The combined power output of +5V and +3.3V shall not exceed 226W.
The combined power output of +5V,+3.3V and +12V shall not exceed 405W
2)When +12V,+5V loading max load ,total output power can be 420W whose
lasting time shall not exceed 15 seconds .The voltage regulation range of any
output loading surge load shall be +/-10%.
3)Input voltage is 220-240Vac ,When peak load.
2.2.3 Output Voltage Line Regulation
The following table specifies line regulation as measured from
minimum to maximum load including the transient response
requirements as detailed in this document.
Table 4. DC Output Tolerance Specifications
DC Nominal Output Output Voltage Tolerance
+12V DC ±1%
+5V DC ±1%
+3.3V DC ±1%
-12V DC ±2%
+5V SB ±1%
2.2.4 Cross Regulation
The power supply DC outputs perform within all line and load specifications
Regardless of the static or transient loads on any of the outputs.
2.2.5 Efficiency
68% minimum at 230VAC, 420W output.
