The VS75E-48/A is a 75W AC-DC power supply with a 48V output, designed for industrial equipment and operating with input voltage from 85 to 132 VAC at 47-63 Hz. It features convection cooling, a typical efficiency of 87%, and supports series operation. The unit is mounted on a PCB with a cover and measures 50 mm × 29 mm × 150 mm. It operates from -10°C to +70°C with derating at higher temperatures, and meets UL62368-1, CSA62368-1, EN62368-1, EN50178(OV II), UL60950-1, CSA60950-1, and EN60950-1 safety standards, along with EMI compliance to EN55011/EN55032-B, FCC-B, and VCCI-B. It includes over-current and over-voltage protection, a hold-up time of 20 ms, and complies with the RoHS directive. The output voltage is adjustable from 43.2 to 52.8 VDC, with a maximum ripple and noise of 240 mVp-p below 0°C. The unit weighs approximately 200 g and meets IEC61000-4 immunity standards.
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.
