The Lambda / TDK EMI TCR80S34 is a regulated power supply with integrated EMI filtering designed to suppress conducted emissions and meet stringent RFI/EMI standards. It combines ferrite toroidal chokes with VDE-listed X and Y capacitors to deliver clean, regulated power across multiple output configurations. Load and line regulation remain tight across the operating envelope, with local or remote programming capability and master/slave operation for flexible system integration.
