THM Medical DC/DC Converters

TRACO Power THM Medical DC/DC Converters come in small, DIP plastic packages with a reinforced I/O isolation system that complies with the medical safety requirements for 2XMOPP (Means of Patient Protection). Available with a wide 2:1 or ultra-wide 4:1 input voltage (WI suffix) range and an internal EMI filter to meet EN55022 class A, the converters constitute a reliable solution for many demanding medical and industrial applications.
