The RTW12-4R3C is a 50W AC-DC power supply with a 12V output, adjustable from 9.6 to 13.2V, and a maximum current of 4.3A. It features a universal input range of 85-265VAC and 150-340VDC, high efficiency of 81-83%, and complies with EN61000-3-2 for power factor. The unit includes overcurrent and overvoltage protection, remote ON/OFF control, and a green LED indicator. Its package measures 22 × 82 × 124 mm and is designed for convection cooling. It meets UL60950-1, CSA60950-1, EN60950-1, and CE Mark safety standards, with a 5-year warranty. The 'C' suffix indicates a cover option for the 50W model.
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.
Having an ultra-low profile, the enclosed RTW series of 50 to 300W power supplies provide solutions where space is extremely limited. The height of the 300W RTW is just 40mm with the 50W model measuring 22mm. Output voltages of 3.3, 5, 12, 15, 24, 28 and 48V cover the most popular applications. All models are convection cooled.
