Original Press Release:

2W and 4W Board Mount Power Supplies Operate from a 90 to 305Vac Input

TDK Corporation announces the introduction of the KAS series AC-DC power supplies, rated at 2W and 4W. Accepting a very wide 90 to 305Vac, 47-440Hz input, these board mounted converters will operate from 115V, 230V and 277V nominal inputs. Target applications include security systems, building automation, professional household appliances, portable equipment and products requiring a separate standby voltage.

The series has a double insulated Class II construction, requiring no earth ground connection and has a 3,000Vac primary to secondary isolation. Available output voltages are 3.3, 5, 8, 9, 12, 14, 15 and 24V and have a no-load power consumption of less than 300mW. The KAS units are encapsulated in a plastic resin fiberglass case, providing additional protection against shock and vibration. The 2W KAS2 measures 28.5 x 25.8 x 17.0 mm and the 4W KAS4 37.0 x 27.5 x 17.5 mm.

The KAS2 will operate in ambient temperatures of -40 to +80°C, derating linearly to 40% load above 60°C. The KAS4 has a temperature range of up to -40 to +70°C, with model dependent derating. All the power supplies are certified to IEC/EN/UL/CSA 60950-1 and are designed to meet IEC/EN 60335-1 with CE marking for the Low Voltage and RoHS2 Directives. The series is compliant to EN 55032-B (radiated and conducted) and will meet EN 55024 immunity standards with an external varistor.
