Increasing the Output Power, Operating Modes

7.5 Operation with External Amplifiers
The connections "LL out 1-6" offer a large variety of extension possibilities.
They enable the connection of external amplifiers in order to increase the
number of independent voltage or current channels and thus provide the
possibility to realize additional applications the CMC 356 alone cannot
cover.
Each LL output socket ("LL out 1-6" and the optional "LL out 7-12") can
connect up to four external amplifiers with six independent channels.
The following configurations are possible:
•9×25A
rms
/ 70 VA for differential relays in three galvanically separated
current triples with CMC 356 + CMA 156.
• 6 × 250 V / 75 VA for the synchronization in two galvanically separated
voltage triples with CMC 356 + CMS 156.
For a complete overview of the supported configurations of the CMC 356
and CMA/S amplifiers see the OMICRON Test Universe Help, topic
Hardware Configuration.
