LM75-10Dxx series of power converter design features two isolated output versions, which can independently supply two different loads in

the system that need to be isolated from each other. The products can be used in harsh working environments with an ambient temperature

range from -30℃to +70℃, without the need of a fan for further heat dissipation. In addition, the converters EMC immunity performance

meets the requirements of IEC61000 standard and meet emission standard CISPR32/EN55032, class B without any external components, thus

providing excellent EMC protection. The products also meet IEC/EN/UL62368, EN60335, GB4943 safety standards. The converters integrate a

variety of protection features and offer a high-performance to low-cost ratio providing the best power solution for a variety of industries such

as industrial control equipment, instrumentation and smart home and building equipment application.
