New Yorker Electronics is now distributing the newly enhanced Cornell Dubilier PC series of AC harmonic filter capacitors. Cornell Dubilier has extended the capabilities of the series, including a new 85 ampere RMS rating and numerous other enhancements.
Type PC capacitors are designed to meet the demands of filter applications rich in system total harmonic distortion (THD). This series has a dual protection system utilizing self healing metallized polypropylene and a mechanical pressure interrupter to ensure a safe open circuit mode in the event of overload or end of life.
Series improvements include its UL recognized construction and internal pressure interrupter system. This internal system has passed rigorous UL testing to ensure fail-open performance under high current fault Source: New Yorker Electronicsconditions. The higher current ratings improve the capacitor’s ability to handle the high levels of harmonic content encountered in inverter AC input and output filtering applications.
The PC series is offered with capacitance ratings ranging from 20 µF to 125 µF at voltage ratings from 300 V AC to 700 V AC. Case diameters vary from 63.5 to up to 116 mm. Custom capacitance and voltage ratings, sizes and performance characteristics are also available. Specific application conditions, especially harmonic content profiles, are needed to properly size the capacitors for peak performance.
The PC series enhancements add capabilities to the broad range of AC harmonic filtering solutions offered by New Yorker Electronics. These include three-phase cylindrical and welded rectangular cases used in large inverter systems. In addition, Cornell Dubilier manufactures rack-mount systems, designed and fabricated in-house, to allow for easy integration of capacitor banks into the mechanical design of a filter system.
