The TMR 3WIR series is a set of 3 Watt DC/DC converters in a SIP-8 metal case.

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 minimum

load is not required.
