The EFE400-12-CCMDS is a 400 W AC-DC power supply with a cover and chassis, no fan, and a 12 V output. It accepts an input voltage range of 90-264 VAC at 45-63 Hz, and meets EN61000-3-2 and EN61000-6-3 for harmonic emissions and conducted noise, Class B. It features reinforced isolation (3 kVAC input to output), overcurrent, overvoltage, and overtemperature protection, and achieves up to 90 % efficiency. It operates from 0 °C to 50 °C with derating above 50 °C, and complies with IEC/EN 62368-1, UL62368-1, and CSA 22.2 No. 62368-1 safety standards. The unit measures 152.4 mm × 127 mm × 42 mm and uses a J1 input connector and J2 output connector. A 12 V / 0.25 A fan supply is included but not accessible in this variant.
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.
