The ZPSA20-3R3 is a 20W AC-DC power supply in an industry-standard 88.9 mm x 50.8 mm x 20.32 mm footprint, designed for applications such as video/audio routers, point of sale, and LED lighting. It provides a 3.3V DC output with a maximum continuous output current of 4.4A and a peak output current of 6.6A, achieving up to 74% efficiency. The unit accepts an input range of 85 to 264VAC (47-63Hz certified) or 120-370VDC, with a leakage current of 0.6mA max at 264VAC, 60Hz. It features continuous short-circuit protection in hiccup mode, overvoltage protection typically between 110-130% of nominal output, and a 12ms hold-up time at 115VAC. The supply complies with IEC/UL/CSA/EN62368-1
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.
Featuring a lower profile and higher efficiency, the ZPSA series is TDK-Lambda's second generation of single output 20, 40 and 60W power supplies. Output voltages are available for the most popular voltages of 3.3 to 48V. The ZPSA20 has a 2" x 3.5" footprint, the ZPSA40/60 a 2" x 4".
