EN 50155 railway approval
Ultra wide 4:1 Input: 9–36, 18–75 and
43–160 VDC
Fully regulated outputs
UL 62368-1 IEC 62368-1
Operating temperature range –40°C to
+80°C
3-year product warranty
The TMR 6WIR series is a set of 6 Watt DC/DC converters in a SIP-8 metal case. They operate up to 60°C environment temperature at full load and up to
80°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
circuit 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.
