The D1SE Series from TDK Corporation are Single-Phase AC-DC Power Supplies that convert AC input voltages of 100-240 V to nominal DC output voltages of 12 V. These power supplies require input DC voltages of 93-300 V and have a power factor of 0.92. They deliver output power up to 120 W and achieve efficiencies of up to 93%. These power supplies include power boost capability and feature a sophisticated thermal design for minimal installation clearances. They have 130% boost-in-power capability, enhanced design flexibility and enable system retrofits. These AC-DC converters have peak inrush energy of less than 0.3A²s, preventing input circuit breakers from nuisance tripping. They are available in DIN rail-mount packages that measure 38 x 125 x 110 mm and weigh up to 460 g. These AC-DC power supplies are ideal for automation, semiconductor fabrication, test, communication, industrial, and renewable energy applications.
