The TMR 3WIR and the TMR 6WIR series are a set of 3/6 Watt DC/DC converters in a SIP-8 metal case. The design purpose of these series was to miniaturized low power DC/DC converters for railway application to the maximum without sacrificing highest efficiency. They operate up to 78°C environment temperature at full load and up to 90°C with a 50% load derating.
With EN 50155 and UL 60950-1 certification, 3'000 VDC I/O-isolation voltage, external On/Off, current limitation 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 a minimum load is not required
