Compact and All-round AC/DC Converter LS-R3 Series

The flyback converter in the switching power supply is the most common AC/DC power supply. With the development of integrated circuit technology, most of the circuits in the flyback converter are integrated into the IC, and there are few peripheral components. That makes it possible to build a power supply that has general functions with just adding a suitable transformer. It’s simple but not optimized for personalized and differentiated needs, engineers are always puzzled to balance the design cycle, cost, reliability, ease of use, dimensions, performance, and personalization of power supply. And now, MORNSUN's newest AC/DC Converter "LS-R3" series can resolve this puzzlement.

Save Cost from Multi-dimension

The cost of the power supply section 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.

MORNUSN LS-R3 series save your cost from Multi-dimension

Design cost: MORNSUN integrates circuit into its self-designed IC which further simplifies the peripheral circuits of the AC/DC Converter LS-R3 series. thereby the number of peripheral components is maximally reduced to save cost.

Manufacturing cost: LS-R3 series is full automation manufacturing. It not only reduces the labor costs but also improves product consistency and pass rate, which makes LS-R3 series provide the most competitive price to customers with low-quality cost and manufacturing cost.

Time cost: We have countless power supply applications and one-to-one support services from FAE to help customers design peripheral circuits according to their own applications, which can shorten product design cycles, save customer’s design costs and time.

Flexible Peripheral Design for a Wide Range of Application

Engineers expect to make a personalized product to meet different electronic devices in the shortest design circle. However, shortening the design time often results in rough product design, and pursuing personalization may make the design complicated with poor compatibility and low economical efficiency.

MORNSUN LS-R3 series shoot customer's troubles with the all-matching core design with a flexible peripheral circuit.

By adopting different peripheral circuits, 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.

Compact Size for Miniaturization Trend

In order to conform to the trend of miniaturization and meet the application requirement of customer in smaller dimensions, the LS-R3 series removes all redundant designs, compacts the circuit layout, replaces the terminals, and design the transformer according to the power section. So the dimensions (26.4x14.73x11mm) are decreased by about 43%.

High Reliability Controlled by Reliable Platform

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 its potential reliability risk. But according to statistical data, it states that most of the cause of failure in electronic devices is the damage of the power supply. Therefore, the power supply is the "key" of the entire system's reliability.

As the below picture showed, the high reliability of MORNSUN LS-R3 series is guaranteed by our reliability platforms. At the same time, massive customer application cases have provided us with countless references input to further optimize our reliability platform, and to ensure our product reliability.

Outstanding Performance to Improve Product Competitiveness

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 requirements; it can work with a full load at -40℃ ultra-low temperature environment, and 50% load at +85℃ high temperature. And it can be compatible with various applications.
