The VS75E-3/A is a 75W single-output AC-DC power supply with a 3.3V nominal output voltage and a maximum current of 15A. It features convection cooling, operates from 85-132V AC at 47-63Hz, and achieves 80% typical efficiency. The unit measures 50 × 29 × 150 mm and includes a protective cover, as indicated by the "/A" suffix. It supports over-current and over-voltage protection with automatic recovery or manual reset, respectively, and maintains output regulation within 0.02% per °C. The power supply meets UL62368-1, CSA62368-1, EN62368-1, and EN50178(OV II) safety standards, complies with EMI standards EN55011/EN55032-B, FCC-B, and VCCI-B, and is rated for operation from -10°C to +70°C with derating above +50°C. It offers a voltage adjustable range of 2.97-3.63V and has a hold-up time of 20ms at nominal input. The device is designed for industrial applications and is RoHS compliant.
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.
