|
Input Line Voltage Range | |
Line Frequency | |
Input Current, Maximum load @ 90 VAC | 2.4 A |
Output Voltage | 19.5 VDC |
Output Current, nominal load | 3.5 A |
Output Current, maximum load | 6.9 A |
Output Current, peak load (300 ms max) [1] | 9.0 A |
NOTES:
Total continuous power should not exceed 135 watts. Total surge power (<10 seconds w/duty cycle < 5 %) should not exceed 170 watts.
[1]Using 100 VAC input. The output voltage is allowed to drop to a minimum of 15 VDC during the transient period.
7.3SFF/CMT Power Distribution
The SFF and CMT form factors use a common power source power supply unit contained within the system chassis. Figure
