DC/DC Railway Converter TMR 6WIR Series, 6 Watt Compact SIP-8 metal case EN 50155 railway approval Ultra wide 4:1 Input: 936, 1875 and 43160 VDC I/O-isolation 3000 VDC Fully regulated outputs UL 62368-1 IEC 62368-1 Operating temperature range 40C to The TMR 6WIR series is a set of 6 Watt DC/DC converters in a SIP-8 metal ca- +80C se. They operate up to 60C environment temperature at full load and up to 80C with a 50% load derating. With EN 50155 and UL 60950-1 certification, Short circuit protection and current 3000 VDC I/O-isolation voltage, external On/Off, current limitation and short limitation circuit protection they cover a wide range of application when space is limited. Remote On/Off The input of the converters is designed for a wide voltage range (4:1) and mini- mum load is not required. 3-year product warranty Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
