The TRN 1SM Series comprises 1 Watt fully regulated, high performance DC/

DC converters. They come in a compact cubical package of only 1.07 cm3. Full

load operation is reliable up tp 90°C environment temperature. With 1’600 VDC

I/O-isolation voltage, and short current protection they cover a wide range of

application when space is limited. The input of the converters is designed for a

wide voltage range (2:1) and minimum load is not required. The functional I/O-

isolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s)

of 1600 VDC.
