The ZMS100-48 is a 100W single-output AC-DC power supply designed for industrial, medical, and broadcast applications, featuring a 2 x 4 inch (50.8 x 101.6 mm) footprint with a height of 31.9 mm. It operates from 85 to 264 VAC and provides a 48 V output with up to 2.1 A under forced-air cooling. The unit achieves up to 90% efficiency, complies with IEC/EN/UL/CSA 62368-1, 60950-1, and 60601-1 standards, and offers 2 x MoPP isolation suitable for BF-type medical equipment. It supports convection cooling at 80W and forced-air cooling at 100W, operates from -20°C to +70°C with derating above 50°C, and meets EN55011/EN55032 Class B conducted and Class A radiated EMI limits. The unit includes hiccup mode overcurrent protection, latching overvoltage protection, and holds up for 84 ms at 100W load under 230VAC input.
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.
With an 80W convection cooled rating and 100W with forced air, this 2' x 4' power supply has been carefully designed to maximise electrolytic capacitor life. The ZMS100 is suitable for both Class I and Class II (no ground) applications and is available with 12V to 48V outputs. Both IEC 62368-1 and medical 60601-1 certifications have been granted. Typical efficiencies are 90%, and with an average efficiency rating of 87%, the ZMS100 meets ErP guidelines. Off load power consumption <0.5W
