DC/DC Converter TMR 2WISM Series, 2 Watt * Ultra wide 4:1 Input: 4.5-12, 9-36 and 18-75 VDC * * * I/O-isolation 1`500 VDC * Protection against short circuit and overload * * Fully regulated outputs Operating temperature range -40C to +80C Remote On/Off 3-year product warranty UL 62368-1 IEC 62368-1 The TMR 2WISM Series is a set of 2 Watt SMD DC/DC converters. They operate up to 70C environment temperature at full load or up to 80C with a 50% load derating. With UL 60950-1 certification, 1'500 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.
