Liberty, SC — Cornell Dubilier Electronics (CDE) is now offering 85A rms ratings and numerous other enhancements for its PC series of AC harmonic filter capacitors. The series


CDE Adds to High-Current AC Harmonic Filter Series


to filter out unwanted frequencies. The presence of multiple har-


monics puts additional stress on capacitors in the form of self-healing. The PC series is designed with robust terminations and low equiva- lent series resistance (ESR) to mini- mize heating. The service life objec- tive of the PC series 60,000 hours when operated at full rated voltage and a case hot spot of 158°F (70°C). The PC series is offered with


capacitance ratings ranging from 20 to 125 µF at voltage ratings from 300


to 700 VAC. Case diameters vary from 2.5 to 4.6 in. (63.5 to 116 mm). Custom capacitance and voltage rat- ings, sizes and performance charac- teristics are also available. Specific application conditions, especially harmonic content profiles, are need- ed 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 the company. These include three-phase cylindrical and

welded rectangular cases used in large inverter systems. Cornell Dubilier also offers rack mount sys- tems, designed and fabricated in house, to allow for easy integration of capacitor banks into the mechanical


design of a filter system. Contact: Cornell Dubilier

improvements include UL-recog- nized construction and an internal pressure interrupter system that has passed the rigors of UL testing to ensure fail-open performance under high-current fault conditions. The higher current ratings improve the capacitor’s ability to handle the high levels of harmonic content encoun- tered in inverter AC input and out- put filtering applications. The series is typically net-


worked with inductors to filter out undesirable harmonics in both sin- gle- and three-phase AC power sys- tems. As a two-terminal capacitor device, multiple PC series capacitors can be connected in delta or Wye con- figurations to achieve the reactive power and harmonic turning needed


High-Density Desktop Power Supplies From TT Electronics


Perry, OH — TT Electronics has launched its new Protek Power N3 series desktop power supplies, further enhancing the company’s ability to deliver high-efficiency AC-DC power solutions to international standards. Optimized for products that


require a high-performance, yet com- pact power supply, the N3 series is designed to support OEMs with high power density in a slimline option. The N3 series offers eight options between 15 to 330W of continuous output power. Enclosed in a 94V-0 rated poly-


carbonate case, all N3 series models meet EN55032 and FCC Class B emission limits, are designed for ITE applications, and are certified to UL, CSA, IEC, and CE standards. In addition, the N3 series is approved to the latest EN62368-1 safety stan- dard, and the EU CoC EPS V5 Tier 2


efficiency standard. Contact: TT Electronics, 3700
