The TMA250 series of 250-W ac/dc power adapters provides dc-output voltages ranging from 12 to 48 V. The series features a 90 to 264-Vac input and 0.9 active power factor. The efficiency is 87% minimum and no-load power consumption is 0.5-W maximum.
The power adapters meet CEC and Energy Star Level V standards and come with a standard IEC320/C14 ac-inlet and a Molex Mini-Fit six-pin or APP PP45-1345 dc-output connector while withstanding 5,656 Vdc from input to output and 2,121 Vdc from input to ground. The power adapters also feature a leakage current of 228 µA at 264 Vac. The series includes overvoltage, overload, and short-circuit protections and is equipped with a thermally-controlled cooling fan. The adapters can be fully loaded at -20° to +40°C.
