TDK-Lambda KAS2 / KAS4 2 and 4W Board Mount Power Supplies Accept a 90 – 305Vac Input

TDK-Lambda announces the introduction of the KAS series of wide input range, 2W and 4W encapsulated AC-DC power supplies.The KAS series can operate continuously from 90 to 305Vac, 47-440Hz, making them ideal for use with 115V,  230V and 277Vac nominal inputs.  Additionally, having a Class II construction, no earth ground connection is required. Input to output isolation is 3,000Vac; this makes the series ideally suited as a low power source for a large number of applications, including building automation, security, professional household equipment and systems requiring an additional standby voltage.TDK-Lambda KAS Series Power Supplies
The KAS is available in 8 output voltages; 3.3, 5, 8, 9, 12, 14, 15 and 24V. Off-load power consumption is <0.3W.  The encapsulated board mount power supplies are enclosed in a UL 94V-0 rated plastic resin fiberglass case for enhanced shock and vibration performance. The 2W and 4W models measure 28.5 x 25.8 x 17 mm and 37 x 27.5 x 17.5 mm respectively. The KAS2 models can operate convection cooled in ambient temperatures of -40 to 80°C, with de-rating above 60°C. The KAS4 operates from -40 to 70°C, with de-rating dependent upon output voltage.
The series has been certified to UL/CSA/IEC/EN 60950-1, is designed to meet IEC/EN 60335-1 and carries the CE mark for the Low Voltage, EMC and RoHS2 Directives.  All models comply with EN 55032-B (conducted and radiated) emissions and EN55024 immunity standards with minimal external components.
