Power Assemblies and Controllers

Energy Storage Capacitors

API Capacitors manufacture standard and customised Energy Storage Capacitors with varying current, voltage, size, mass and terminations. Elements are wound on the latest precision edge controlled automatic winding machines. High conductivity copper is used for low resistance internal connections.

API Capacitors are finished in powder coated corrosion free metal or insulated cases and filled with an environmentally safe oil or dry leak free resin.

Energy Storage Capacitors are used predominantly across the Military, Medical and Industrial markets.
