The VS50E-3/A is a 50W single-output AC-DC power supply with a 3.3V DC output, conforming to UL62368-1, CSA62368-1, EN62368-1, EN50178(OV II), UL60950-1, CSA60950-1, and EN60950-1 safety standards, and designed to meet EN55011/EN55032-B, FCC-B, and VCCI-B EMI requirements. It operates from 85-132VAC input at 47-63Hz, with typical efficiency of 80% at 100VAC and 25°C. The unit features convection cooling, a -10°C to +70°C operating temperature range with derating above +50°C, and measures 50 x 23 x 132 mm. It includes over-current and over-voltage protection, adjustable output voltage from 2.97V to 3.63V, and is offered in a PCB mount configuration with a cover. Hold-up time is 20ms, and leakage current is less than 0.5mA. The /A suffix indicates an enclosed version.
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.
