How to Choose the Right MORNSUN AC/DC Power Supply

Selecting the right AC/DC power supply is a foundational step in any electronic system design. The choice impacts reliability, performance, and cost. MORNSUN offers a vast portfolio, and this guide will help you navigate it effectively.

1. Determine Your Power and Voltage Requirements

The most basic step is to define the required output voltage(s) (e.g., 24V, 12V, 5V) and the maximum output power (in Watts). Always add a derating margin of at least 20-30%. For a system requiring 60W, a 75W supply like the LM75-20B24 provides a safe operating margin.

2. Consider the Mechanical Form Factor

How will the power supply be mounted? MORNSUN offers several options:

• Enclosed/Chassis Mount: Ideal for standalone industrial equipment. (e.g., LM Series)
• DIN-Rail: For easy installation in control cabinets. (e.g., LI Series)
• Board Mount (PCB): Compact modules for integration directly onto the system board. (e.g., LS Series)
• Open-Frame: For applications where the supply is enclosed within the system chassis. (e.g., LOF Series)

3. Evaluate EMC and Safety Standards

For industrial applications, compliance with standards like EN55032 Class B for emissions is crucial. For medical equipment, you must look for modules compliant with EN60601-1 (2xMOPP). Choosing a pre-certified module saves significant development and testing time.
