Model LKT-F -Power Electronics Capacitors
FRAKO Type LKT-F capacitors are power electronic capacitors which are designed specifically for use with non-sinusoidal voltage and current including Pulse Width Modulated (PWM) voltage. Type LKT-F capacitors may be used in various types of filters for use at the input or output side of inverters and drives. They may be applied in either DC (VN ratings) or AC (Vrms ratings) filter circuits.
The new FRAKO power electronics capacitors type LKT-F are manufactured using a unique dry technology. Up to three capacitor coils made of low-loss metallized polypropylene are connected inside the cylindrical aluminum housing with M12 mounting bolts to form the finished capacitor. In addition to a PCB-free, flame-retardant, mineral filling material, an adhesive stabilizer is used. The electrical connection is made via the finger-safe connecting terminal (AKD), which, through the proven spring clamp technology, establishes a maintenance-free connection to the connecting cables or via the screw connection. The use of strictly tested materials and careful processing guarantee quality and a long product lifespan.
FRAKO manufactures its power electronics capacitors according to in-house specifications that far exceed applicable standards. Quality inspections after each production stage ensure a high-quality end product. Due to the high quality standards and special manufacturing technology, FRAKO power electronics capacitors achieve an above-average lifespan. At the end of the production process, each capacitor undergoes a special test. The internal requirements for this test significantly exceed the standard specifications for routine tests. Capacitors developed and produced at the company`s location in Teningen, Germany, ensure consistently high quality, operational safety, and a long lifespan.
