SYSTEM OVERVIEW
LAI6/B POWER SUPPLY
The general output specifications for the
LA16/B
power supply is
shown in the following table (Figure 2-18). It shows the minimum
and maximum values of current generated per the output voltages.
The power supply unit is able to provide a stationary power of
182 watts.

Figure 2-18. Power Supply Output Characteristics
Note: An inlpulsive repetitive load with maximum
1/5
duty cycle and behavior is allowed on the +12 V. An
impulsive load is allowed on the + 12 V to be added to the
static load in the power-on transition where a deviation
from the rated tolerances of the output voltages is allowed.
The worst load crossings allowed with no power take-off on
+
