9.2.2 LA-POWER US mono-phase circuits
Connect LA-RAK US to AC mains only if the operating voltage indicated on the LA8 back panels
corresponds to the local AC mains rating.
Two LA8 versions are available (also refer to the
“LA8 – User Manual” ):
•
A universal 120/230 V (±10 %) version fitted with automatic switch mode power supply.
•
A specific 100 V (±10 %) version for Japan.
The LA-POWER US three-phase circuit described in the above section powers the three mono-phase circuits
corresponding to the three
L5-30 female outlets located on the rear face (L1, L2, and L3). These last allow connection
of the three LA8 amplified controllers mounted in the LA-RAK US (see Figure 34).
Each outlet is protected by a
30 A
circuit breaker located on the front face and three LED help monitor the presence
of each phase on the front end of the mains circuit.
The LA-POWER US also includes an
auxiliary circuit protected by the “Aux” 20 A circuit breaker. This circuit powers
six duplex outlets located on the front and rear faces to connect portable computer and the like as well as additional
Ethernet
®
switches.
