General characteristics
The equipment consists of one or several racks
of capacitors installed in an enclosure. Each rack
represents a reactive power expressed in kVAR.
The racks are divided into steps which are connected
or disconnected automatically, according to the reactive
power required.
The COSYS automatic PFC PFC system are designed
to offset variable reactive energy. Reactive energy
consumption may come from a factory or a production
unit.
• Power from 17.5 to 900 kVar.
• Harmonics from 0 to 100% in 4 stages: PFC41,
PFC42, PFC43, PFC44.
• Cable input at the bottom (can be the top if required).
• Base plate optional
• Thermal regulation with fan (depending on equipment).
• 6 or 12 output power factor correction regulator
depending on the model, with alarm relay.
• Self-healing capacitors.
• Capacitor cut off from the automatic circuit in case of
removal.
• Steel panel enclosure colour RAL 7035.
• IP rating IP20, IP30 depending on model.
• Rated voltage: 400 V three-phase.
• Rated frequency: 50 Hz.
• Operating temperature: -5°C to 40°C.
• Tolerance on capacitor capacity value: -5, +5%.
• Discharge device on each bank: < 50 V after 1 minute.
• Capacitor internal connection: delta.
