Applications Without Using HiGain Doublers
General
This section addresses HLU-200 List 1D operation when used without doublers. For applications without
doublers, the HLU-200 is directly connected to the HRU-412 by the two cable pairs.

Power Parameters

Table 8 lists the non-doubler HLU-200 List 1D's current drain on the 4 CBA's power supplies, its power
consumption, and dissipation. The same parameters are shown for two other higher power CBA plugs, the
AT1U and REBS, for comparison.
The maximum power dissipation measures the power that is converted into heat build up within the unit. It
contributes to the total heat generated in the space around the unit.
The maximum power consumption is the total power that the HLU-200 List 1D consumes or draws from the
CBA's power buses. This parameter is needed when the Litespan-2000 is battery powered. It determines the
battery capacity required to maintain an 8-hour stand-by battery reserve for emergency situations.
