The TRN 3 Series comprises 3 Watt fully regulated, high performance DC/DC
converters. They come in a compact cubical package of only 1.00 cm3. Full load
operation is reliable up tp 65°C environment temperature. With 1’600 VDC I/O-
isolation voltage, and short current protection they cover a wide range of ap-
plication 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.
