TMR 2-4812WIN TRACO Power

DC/DC Converter TMR 2WIN Series, 2 Watt Ultra-wide 4:1 input range Compact SIP-8 package Temperature range 40 to +90C (up to +75C at full load) High efficiency of 82% Excellent load and line regulation UL 62368-1 IEC 62368-1 Continuouse short-circuit protection The TMR 2WIN series is a family of isolated 2 W DC/DC converter modules with accurately regulated output voltages and ultra-wide 4:1 input voltage Overload protection ranges. They require no minimum load and are protected against overload and I/O isolation 1500 VDC short circuit. An excellent efficiency along with the use of high grade components allows a Remote On/Off control compact construction in SIP-8 package even the converters can reliably oper- 3-year product warranty ate in an ambient temperature of 40C to +75C at full load and up to 90C with 50% power derating. Typical applications for these converters are distrib- uted power architectures in communication, instrumentation and industrial electronics, everywhere where space on the PCB is critical.
