TMR 1-4823SM TRACO Power

DC/DC Converters TMR 1 & TMR 1SM Series, 1 Watt CB Scheme Features Wide 2:1 input voltage range Compact SIP-6 or SMD package Fully regulated outputs Cost optimised design No minimum load required Continuous short circuit protection Temperature range 40C to +85C I/O isolation 1500 VDC Remote On/Off control (SMD) The TMR-1 and TMR 1SM series are families of isolated 1 W dc-dc converter mod- ules with regulated output, featuring wide 2:1 input voltage ranges. These products 3-year product warranty come in a compact SIP-6 or SMD package with small footprint occupying only 1.2 2 cm (0.2 square inch) of board space. An excellent efcfi iency allows 40C to +85C operation temperature. Further fea - tures include remote On/Off control (SMD-Version) and continuous short circuit protection. The compact dimensions and cost optimised design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial electronics.
