The Lambda/TDK EMI TCR80T60-1 is a power supply component engineered to reduce electromagnetic and radio frequency interference in demanding industrial applications. It delivers stable, filtered DC power by suppressing conducted RFI on the AC input line by a factor of 1000 compared to previous SCR models. The internal filter architecture uses ferrite toroidal chokes and VDE-listed X and Y capacitors to achieve 25 mV output ripple at full load without electronic ripple elimination circuitry.
