TMR 3-1210WIE TRACO Power

DC/DC Converter TMR 3WIE Series, 3 Watt Wide 4:1 input voltage range Compact SIP-8 package Cost optimized design Temperature range 40C to +85C I/O isolation 1600 VDC UL 62368-1 IEC 62368-1 Remote On/Off control The TMR 3WIE series is a family of isolated 3 W DC/DC converter modules with 3-year product warranty regulated output, featuring wide 4:1 input voltage ranges. The product comes in a compact SIP-8 plastic package with small footprint occupying only 2.0 cm (0.3 square inch) of board space. An excellent efficiency allows 40C to +85C operation temperature. Further features include remote On/Off control and continuous short circuit protection. The compact dimensions and cost optimized design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial electronics.
