The TDN 3WISM Series comprises 3 Watt fully regulated, high performance DC/
DC converters. They come in a compact cubical package of only 1.23 cm3. Full
load operation is reliable up tp 70°C environment temperature. With 1’600 VDC
I/O-isolation voltage, external On/Off, 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 (4:1) 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.
