DESCRIPTION:

REMARKS:

  Power consumption under nominal load conditions (no ACD), 25 degC, 20MHz clock: Primary (Powered through JL-40) = 10.68W, see TD-06888 section 5.2.2

Redundant (powered through JL-41) = 10.80W, see TD-06888 section 5.2.18
 
  Power consumption under low, nominal, and high load conditions of GASU with simulated ACD load at
25 degC, 20 MHz clock (TD-06888, section 5.2.16):
 
Low
Primary = 22.24W
Redundant = 22.26W
Nominal
Primary = 28.17W
Redundant = 28.22W
High
