The KMS15A-12 is a 15W, PCB-mount AC-DC power supply with a 12V output, designed for medical and industrial applications requiring double insulation and no earth ground. It features 4kVac input-to-output isolation (2x MOPP), operates from -40 to +80°C with derating, and meets IEC/EN 60601-1 and IEC/EN 62368-1 safety standards. Ripple and noise are rated at 150mVpk-pk, with 84% efficiency at 230Vac. The unit measures 52.5 x 27.5 x 23.5 mm and weighs 60g, with an epoxy encapsulated plastic case (UL 94V-0). It has <0.1W no-load consumption, holds up for 15ms at 115Vac, and includes overcurrent and overvoltage protection with auto-recovery.
AC-DC converters have the functionality to extract a stable DC power supply by rectifying and controlling commercial power supplies. TDK offers an abundant lineup of TDK-Lambda brand AC-DC switching power supplies that adopt the "switching method" for the industrial equipment market. These power supplies are available in unit types, PC board types, power module types, on-board types, and DIN rail mount types, with a wide-ranging product lineup from models with a small capacity of several W to models with a large capacity exceeding 2 kW. TDK-Lambda offers "standard power supplies" that meet the various needs of its customers for keeping up with the changing times, including miniaturization and efficiency enhancement, compliance with safety standards, support for wide input, compliance with EMI (electromagnetic interference) standards and higher harmonic current regulation, compliance with the RoHS directive, and the adoption of digital control technologies.
Designed for medical and industrial applications that require robust, encapsulated, lightweight and compact power supplies, these sealed KMSA supplies resist dust, and humidity. The series is available in 15W, 30W and 60W power levels, with single output models covering the most common voltage combinations. The Class II double insulated construction allows the product to be operated without an earth ground connection
