TMR 2-0523WISM TRACO Power

DC/DC Converter TMR 2WISM Series, 2 Watt Ultra wide 4:1 Input: 4.512, 936 and 1875 VDC I/O-isolation 1500 VDC Fully regulated outputs Operating temperature range 40C to +80C UL 62368-1 IEC 62368-1 Protection against short circuit and overload 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 Remote On/Off derating. With UL 60950-1 certification, 1500 VDC I/O-isolation voltage,exter- nal On/Off and short current protection they cover a wide range of application 3-year product warranty when space is limited. The input of the converters is designed for a wide volt- age range (4:1) and minimum load is not required. Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
