Three-Phase Filter Cleans Up Wind Power

For applications in renewable energy equipment, UPS, inverters, and power inverters with a maximum operating voltage up to 720 Vac, HCWMGF-series filters clean up the radio frequency noise unintentionally injected into the network that typically ranges from 10 kHz to 30 MHz. The components provide three stages of filtering. Features include an insertion loss above 40 dB in the whole range reaching 80 dB between 200 kHz and 1 MHz, a dielectric strength above 3 kVdc, and a UL94 V2 rating. The HCWMGF series is available in a three-phase version L1, L2, L3 (without neutral) from 150A to 2,500A with power losses less than 0.02%. PREMO GROUP, Barcelona, Spain, +34 934 098 980.
