Introduction

Aiming at miniaturization, light weight, 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 light weight

The dimensions is 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-rounder periphery

The series shoot 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 the extremely harsh outdoor environments.

4) Low consumption and high efficiency

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

b. The efficiency up to 77%.
