Fully regulated outputs
Operating temperature range
-40°C to +70°C without derating
Remote On/Off
Designed to meet IEC/EN/UL 62368-1
(not certified)
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/UL 62368-1
(not certified) with a test voltage (60 s) of 1'600 VDC.
