3 times the current ratings limited to 270A
Up to 4 power units/filter (power units must have same rating).
One power unit per enclosure.
Power units can be master or slave type
For full redundancy combine master units of same rating.
If any unit in a master-master filter system fails, the other units can
keep running.
For limited redundancy combine master with slave units of the same
rating.
If any slave unit in a master-slave filter system fails, the other units
can keep running.
If the master in a master-slave filter system fails, the complete system
stops running.
15 harmonics individually selectable in the range 2
order if the neutral is connected.
20 harmonics individually selectable in the range 2
order if the neutral is not connected.
Programmable per harmonic in absolute terms
