The PH75A280-12/T is a 75W isolated DC-DC converter in the PH-A series, designed for 200 to 425VDC input and delivering a 12V output adjustable from 9.6 to 13.2V. It features remote sense, remote on/off control, and conduction cooling capability. The unit has a baseplate cooling design, operates with a -40°C to +100°C baseplate temperature range, and meets IEC/EN62368-1 safety standards. Its dimensions are 37.2 x 12.7 x 58.3 mm, and it weighs 55 g. The /T suffix indicates non-threaded 3.3mm mounting inserts. Efficiency at 280V input and full load is 89%, with ripple and noise of 150mV. Overvoltage protection is active, and parallel operation is not permitted.
The DC-DC converter is a type of switching power supply that converts direct currents of buslines into direct currents that are needed for devices. TDK has a lineup of DC-DC converters under the TDK-Lambda brand for the industrial equipment market boasting high-reliability and long service life made possible with advanced circuit designing technology and high-density mounting technology. The lineup of DC-DC converters by TDK-Lambda also includes isolated and non-isolated types to meet various applications along with onboard, power module and unit types and a wide range of industry-standard sizes from brick-shaped to inch-sized.
