Alpistatic automatic capacitor banks

 
 

 

Alpistatic capacitor banks are automatic banks with switching via solid state contactors. They provide "soft, fast" reactive energy compensation suitable for receivers that are sensitive to voltage variations or that have ultra-fast cycles.


Principle

Alpistatic capacitor banks consist of :

- 1 three-pole solid state contactor by fan-cooled heat sink
- 1 set of 3 HRC fuses per step
- 1 system for controlling the solid state contactors
- Standard and H type: 3 single phase damping reactors protecting the solid state contactor
- SAH type: 1 three-phase detuned reactor protecting the solid state contactor and providing protection again harmonics


General characteristics

- IP 31 - IK 05 cabinet
- Protection of parts under power against direct contact: IP 2X
- Temperature class
Operation: -10 / +45°C (average over 24 hours: 40°C)
Storage: -30 / +60°C
- Ventilation: forced
- Color: grey cabinet (RAL 7035),black base
- Cables enter at the bottom (at the top on request)

Conform to EN 60439-1 and IEC 60439-1 standards
