Appendix B: Chassis Specifications
1
This specification applies to Keysight M 9018A chassis serial num bers TW 52460101 and later.
Chassis w ith prior serial num bers lim ited low -line pow er to 900W nom , 667.5 W DC Output Pow er.
1
The maximum current from each supply is the same for both low-line and
high-line inputs. However, the total power
supplied for all rails (except 5 Vaux) must not exceed 710 W on low-line
(100-120 Vac input)
2
The total power supplied for all rails (except 5 Vaux) must not exceed 860 W.
3
The total power supplied for 3.3 V, 12 V, and -12 V rails must not exceed 616 W.
4 For Keysight M9018A chassis with serial numbers before TW52460101, the
maximum current allowed on the +12 V rail was 47.2 A.
