5.2 Single Phase Operation
Series Circuit 1,2 (L-L)
Maximum output voltage: 20V
rms
Maximum power: 280VA at 15A
Current range: 1 0 … 50A
rms
If currents 1 and 2 of a CMA 56 are operated in phase opposition (180°), the
output power can be doubled.
In order to maintain a valid overload display in this case, the outputs must be
connected with low resistance.
