AC filtering power electronics capacitors are used at the output of DC/AC inverters where extreme operating conditions are required with very high AC voltages, such as wind generators, solar inverters, UPS applications, harmonic filtering with unusual levels of harmonic distortions or those cases in which the current is not sinusoidal and with pulses.
RTR Energía’s EPC FT (three-phase AC filter capacitor) and EPC FS (single-phase AC filter capacitor) capacitors offer very low resistance and inductance, thus meeting the different needs of customers.
RTR Energía’s manufacturing experience allows it to offer a wide variety of filter capacitors at different voltages and capacities made with the best quality materials. These capacitors also have a safety system by disconnection due to overpressure and V0 self-extinguishing polyurethane resin, with certification. UL94 and manufactured by RTR Energía with certification number: 20141031-E470994.
