The SL Power Electronics GNT428ABTG is an enclosed AC/DC converter designed for ITE (Commercial) and Medical applications. It delivers 400W of continuous output power with a universal input voltage range of 90-270 VAC.
Key electrical specifications include a typical efficiency of 91% at 230VAC and 88% at 120VAC, with active Power Factor Correction (PFC). The unit offers adjustable output voltage with ±5% minimum adjustability and features like remote sense, standby output, and overvoltage protection.
Mechanically, the GNT428ABTG is designed for chassis mounting with dimensions of 177.8mm x 100.0mm x 40.0mm. It operates within a temperature range of 0°C to 70°C with derating. Safety certifications include CE, cURus, and DEMKO, making it suitable for demanding applications.
Normal input voltage is 100-240 VAC, with a maximum range of 90-270 VAC.
Continuous output is 400W at 10.7A, with a peak output of 450W for 1 minute (10% duty cycle).
Typical efficiency is 91% at 230 VAC and 88% at 120 VAC.
The converter operates from 0°C to 70°C with derating.
Enclosed chassis mount package.
Overload protection triggers typically at 470W.
The output recovers to within 1% in 500 µs for a 50% load step.
