Mornsun AC/DC Switching Power Supplies

Open frame power supplies are PCB assemblies without enclosure, offering lower cost and smaller size for integration into equipment. Enclosed power supplies have metal or plastic housings providing touch-safe design and environmental protection. Choose open frame for internal integration, enclosed for standalone applications.

Choose open frame for equipment integration. Choose enclosed for standalone or user-accessible applications.

Mornsun power supplies include comprehensive protection: Overvoltage Protection (OVP) prevents output voltage from exceeding safe limits. Overcurrent Protection (OCP) limits output current during overload. Overtemperature Protection (OTP) shuts down the supply if internal temperature exceeds safe limits. Short Circuit Protection (SCP) protects against output short circuits. These features ensure safe operation and protect connected equipment.

All Mornsun supplies include standard protections. Contact us for applications requiring special protection features.

Mornsun power supplies offer high efficiency ranging from 88% to 95% depending on the model and load conditions. Higher efficiency means less heat generation, lower operating costs, and reduced cooling requirements. Efficiency is typically specified at nominal input voltage and full load. Actual efficiency varies with input voltage and load conditions.

Choose higher efficiency models for applications where heat dissipation is critical or for energy-saving requirements.

Mornsun power supplies offer wide operating temperature ranges, typically from -30°C to +70°C or -40°C to +85°C depending on the model. Some products may require derating at high temperatures. The wide temperature range makes them suitable for industrial environments, outdoor applications, and harsh conditions.

Select models with appropriate temperature range for your application environment. Consider derating requirements at high temperatures.

Mounting options vary by product type: Chassis mount supplies use screws to attach to equipment chassis or panels. DIN rail supplies snap onto standard 35mm DIN rails for control panel installation. PCB mount converters solder directly to printed circuit boards. Open frame supplies are designed for integration into equipment with custom mounting.

Choose mounting type based on your equipment design. DIN rail for control panels, chassis mount for equipment integration, PCB mount for on-board power.
