TMR 2-4821WI TRACO Power

DC/DC Converter TMR 2WI Series, 2 Watt Ultra-wide 4:1 input range SIP-9 package Temperature range 40 to +85C High efficiency Excellent load and line regulation The TMR 2WI series is a new family of isolated 2W DC/DC converter modules Indefinite short-circuit protection with regulated output, featuring ultra-wide 4:1 input voltage ranges of 9-36 I/O isolation 1500 VDC VDC or 18-75 VDC. The product comes in a ultra-compact SIP-9 plastic pack- age. Remote On/Off control An excellent efficiency up to 84% allows 40C to +85C operation tempera- Fully RoHS compliant tures at full load. Further features include remote On/Off control and continu- ous short circuit protection. Typical applications for these ultra-compact con- 3-year product warrenty verters are battery operated equipment and distributed power architectures in communication, instrumentation and industrial electronics, everywhere where space on the PCB is critical.
