1-5W Non-isolated AC/DC Converter in "305RAC”Family——LSxx-K3BxxSS

Introduction

Aiming at miniaturization, the lightweight, non-isolation trend of IoT and smart home applications, MORNSUN launched ultra-light and compact non-isolated AC/DC power supplies with 1~5W in the "305RAC (reliable under all conditions)" family——LSxx-K3BxxSS. The series with 5W is only 16.13 * 15.10 * 9.50mm, and it also features low consumption of 0.1W and high efficiency of 77%.

Advantages

1）Miniaturization and lightweight

The dimensions are only 16.13 * 15.10 * 9.50mm, and the weight is only 4.5g, which greatly improves the space utilization for customers.

2）Wide input voltage：85 - 305VAC/70-430VDC

This series meets global voltage requirements such as 110/220/277VAC standard voltages;

3）All-round periphery

The series shoots customer's troubles with the all-matching core design with a flexible peripheral circuit. By adopting different peripheral circuits, the series can be used in almost all applications including low-cost consumer products and even high-end power for extremely harsh outdoor environments.

4）Low consumption and high-efficiency

a. No-load consumption as low as 0.1W;

b. The efficiency by up to 77%.
