The KMS30A-12 is a 30W, PCB-mount AC-DC power supply providing a 12V output for medical and industrial use. It features 4kVac input-to-output isolation (2 x MoPP), meets IEC/EN 60601-1 and IEC/EN 62368-1, and complies with EN55011 Class B emissions. Operating from -40°C to +80°C, it delivers 89% efficiency at 230Vac with 150mVpk-pk ripple. Input range is 90-264Vac, with inrush current of 30A at 115Vac. No load power consumption is less than 0.15W. Dimensions are 64.1 x 45.6 x 23.5 mm, weight is 135g, and the case is UL 94V-0 plastic. Overcurrent protection is hiccup mode with auto-recovery; overvoltage protection uses a zener clamp. MTBF is 200,000 to 400,000 hours at 25°C, with a three-year warranty.
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
