TRN 3-1222SM TRACO Power

DC/DC Converter TRN 3SM Series, 3 Watt Compact SMD package 11,9 x 11,3 x 8,0 mm Fully regulated outputs Input Voltage range 4.5-13.2, 9-18, 18-36, 36-75 VDC I/O-isolation 1600 VDC The TRN 3SM Series comprises 3 Watt fully regulated, high performance Operating temperature range DC/DC converters. They come in a compact cubical package of only 1.07 cm. 40C to +85C Full load operation is reliable up tp 65C environment temperature. With 1600 VDC I/O-isolation voltage, and short current protection they cover a wide range Short circuit protection of application when space is limited. The input of the converters is designed for Designed to meet UL 62368-1 (UL a wide voltage range (2:1) and minimum load is not required. The functional 60950-1) I/O-isolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC. 3-year product warranty Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
