TDK-Lambda iEH series isolated DC-DC converters

The 300 W TDK-Lambda iEH series of isolated DC-DC converters, featuring digital nonlinear adaptive control, provide good dynamic performance and system stability with a reduced component count.

Operating from a 48 VDC nominal input, the series can provide output voltages of 9.6 to 12 V with currents up to 33 A. The series is designed to meet a wide range of applications, including ICT equipment, semiconductor manufacturing equipment, measuring equipment and general industrial equipment.

The converters are in the industry-standard eight-brick package and include a baseplate with mounting holes for use with an external heatsink. Optimisation of components using digital control enables up to 192 W of output power with only 200 LFM airflow at 85°C.

Input to output isolation is 2250 VDC and input to baseplate is 1500 VDC. All models feature remote on/off as well as overcurrent, undervoltage, overvoltage and overtemperature protection.
