The HWS300-3 is a 300W single-output AC-DC industrial power supply offering a 3.3V output with an input range of 85 to 265Vac and 47 to 63Hz. It features a limited lifetime warranty, Class B conducted and radiated EMI compliance without external filtering, and meets IEC 62368-1 and UL 508 safety standards for 5V, 12V, 24V, and 48V models. The unit operates from -10°C to +70°C with forced air cooling, has a size of 61 x 82 x 165 mm, and uses screw terminals. Efficiency is 74% at 115Vac and 77% at 230Vac, with an input current of 3.8A at 100Vac and 1.9A at 200Vac. The output ripple and noise is 120mV peak-to-peak, and it includes remote on/off, remote sensing, and parallel operation capability. Overvoltage protection is latch-type, and overcurrent protection exceeds 105% of rated current. Weight is 1,000g, and MTBF is 2,145,809 hours under specified conditions.
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.
The HWS comes with a limited lifetime warranty and was a first in the industry when announced in 2008. The highly reliable 300, 600, 1000 and 1500W fan cooled models form part of a very broad HWS product offering ranging from 3.3V to 60V outputs. A 1-6V program input (on select models) can adjust the output from 20-120% of nominal for applications requiring non-standard voltages. Certifications include IEC/EN/UL 62368-1 and UL 508 (most HWS300, 600 models)
