20W Ultra-thin Plastic DIN Rail Power Supply LI20-20BxxPU Series.jpg

MORNSUN's new ultra-thin plastic DIN rail power supply series, LI20-20BxxPU, offers a wide range of output voltages, including 05/12/15/24 V.

This series features constant current limitation, a universal full-range AC input, 4000VAC high isolation voltage, and a 3-year warranty, providing a stable and safe power supply for customers’ applications.


1. Wide input voltage range

85 - 264VAC/120 - 370VDC, AC or DC input at the same terminal

It can take power directly from the system DC bus, simplifying the layout of the system wiring

2. High performance

  • Efficiency up to 86%

  • Operating temperature range: -30℃ to +70℃

  • Output short circuit, over-current, over-voltage protections

  • Constant current limiting function, solves the problem of capacitive loads and inductive loads such as motors

3. Ultra-thin design

The dimension of (WxHxD) 22.50 × 95.00 × 85.00mm, which is 10% smaller and 83% lighter than the similar product, can meet the compact chassis requirements. The standard DIN rail mounting can be directly replaced in the existing design and increase space utilization in the new design.

4. High reliability

  • Isolated voltage of 4000VAC for high withstand voltage requirements

  • EMI: CE & RE meets CLASS B

  • Design refers to EN/IEC/UL62368, UL61010, and UL508 standards


The products can be widely used in the fields of industrial control equipment, machinery, rail transit, and other industrial equipment in a variety of harsh environments.

The products should be used in a natural air cooling environment, if used in a closed environment, please contact our FAE team.
