SYSTEM OVERVIEW
LA16/B POWER SUPPLY
The general output specifieations 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 impulsive repetitive load with maximum 1/5
duty cycle and behavior is allowed on the 4-12 V. An
impulsive load is allowed on the -1-12 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
-1-15 V are as follows:
I (+12 V) 0.9 A (min) — I (+5) 14.3 A (max)
I(+5 V) 6.2 A (min) ^ I (+12) 4.5 A (max).
