TRN 1SM Series, 1 Watt
Input Voltage range
4.5-13.2, 9-18, 18-36, 36-75 VDC
Operating temperature range
–40°C to +90°C without derating
Designed to meet UL 62368-1 (UL
60950-1)
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.
