212 Technical specifications Manual Power Quality Filter PQFS
Network current ratings 3 times the current ratings limited to 300A for PQFS 120 A
Modularity Up to 8 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.
Harmonics that can be filtered 15 harmonics individually selectable in the range 2
– 50
harmonic order if the neutral is connected.
20 harmonics individually selectable in the range 2
nd
– 50
th
harmonic order if the neutral is not connected.
Programmable per harmonic in absolute terms
Better than 97% of filter rating typically
Response time 40 ms typically (10% - 90% filtering)
Reactive power Static/dynamic
Power factor programmable from 0.6 (inductive) to 0.6
(capacitive)
Load balancing Off
Phase to phase, phase to neutral (if neutral present), both
(if neutral present)
Setting possibilities Main and auxiliary settings functionality.
Three possible filter modes that allow to set different
priorities
Start and stop settings Local/remote control functionality.
Filter standby functionality.
Auto restart after power outage functionality.
2 multipurpose digital inputs on PQF-Manager.
Vlow: 0 Vdc, Vhigh: 15-24 Vdc, driving current: 13 mA@
24Vdc (Rint = 1.88 kΩ).
Can be used to implement remote control functionality,
start/stop buttons and switching between main and
auxiliary settings.
6 multipurpose (NO) digital outputs on PQF-Manager.
Maximum continuous ac rating: 440 Vac/1.5 A
Maximum continuous dc rating: 110 Vdc/0.3 A
Common rating: 9A/terminal, totaling 18 A
