CMF200 – Rote Karte für Störenfriede!

Common mode interference effectively suppressed: Ready-to-install filter protects controls and industrial PCs!
Ready to mount on a top hat rail or open frame for direct installation in devices: Not much bigger than a matchbox is the 200 W common mode filter CMF200 from Elec‑Con, a development house for customer-specific power electronics up to 1 kVA. The heart of the filter is a current-compensated choke, which reliably keeps annoying common mode interference from switching power supplies away from sensitive electronics such as panel and box PCs. In the sensitive frequency range 20…50 MHz, the attenuation is up to 20 dB.
The common mode filter CMF200 is designed for operating voltages up to 50 VDC and continuous currents up to 4 A (peak current 6 A). Customer-specific filter characteristics are possible, as is an adapted current carrying capacity. Conveniently integrated is a reverse polarity protection that responds within 25 ns to effectively prevent damage to the downstream application.
