LS R3 Series – Wide-Input, Compact & High-Density Power

Relec Electronics are proud to announce the new LS R3 Series from Mornsun Power. The new generation of compact, wide-input AC/DC Converters, with an emphasis on a miniature and flexible layout design, capable of delivering 3 – 10 watts of high-density power.

Compact Size

Design engineers face many challenges in all stages of a project. Constantly reviewing the cost, reliability, ease of use, dimensions, performance, and personalization of any design. In a growing trend of miniaturization, it’s hugely important to have a reliable, wide-input power converter that can deliver effectively in a smaller environment.

Recognizing this growing trend, Mornsun Power have produced a cost-effective AC-DC Converter solution for design engineers, with an emphasis to be smaller, lighter, and flexible – but without sacrificing efficiency in such compact designs.

Wide AC/DC Input Power

The LS R3 Series has achieved a wide input voltage range of 85 – 305Vac, which can meet the global universal voltage requirements. The static power consumption is as low as 0.1W, which meets the six-level energy efficiency and is suitable for many industries with high power consumption.

All the products from the R3 range are fully functional with a full load at -40°C in ultra-low temperature environments, and 50% load at +85°C high temperatures. Mornsun Power are also very proud to offer custom solutions depending on your type of application needs.

All-In-One Design

The flyback converter in the switching power supply, is the most commonly used in any AC-DC Converter. With the development of integrated circuit technology, most of the circuits in the flyback converter are integrated into IC. This makes it possible to build a power supply that has general functions, whilst additionally adding a suitable transformer. It’s simple but not optimized for personalized builds and designs. Mornsun Power’s newest LS R2 AC-DC Converter Series can now resolve this issue as an all-in-one, flexible design converter.

Extremely Reliable

By adopting different peripheral circuits, the LS R3 can be used in almost all applications including low-cost consumer products, and even high-end power for the extremely harsh outdoor environments.

The circuit of the flyback converter in the power supply product is simple and easy to be designed and produced, engineers maybe generally not taken seriously to i. potential reliability risk. But according to statistical data, it states that most of the causes of failure, is the damage of the power supply. Therefore, the power supply is the key of the entire systems reliability.

The high reliability of the LS R3 Series is guaranteed by Mornsun’s reliability platforms. At the same time, massive customer application cases have provided Mornsun with countless references and input, to further optimize and ensure product reliability.

Saving Costs

The cost of any power supply accounts for a large proportion of the cost of electronic devices, forcing many customers to use discrete solutions to reduce costs. But discrete solutions can only reduce raw material cost there’re still multiple types of cost included such as design cost, manufacturing cost time cost, management cost, quality cost, and invisible risk cost, etc.

The LS R3 Series not only reduces the Labor costs but also improves product consistency and pass rate, which makes LS-RS Series provide the most competitive price to customers with low-quality cost and manufacturing cost.

All products in the LS R3 Series are IEC/EN/UL62368 Approved
