Mornsun LMF320-23B05 Power Supply
The Mornsun LMF320-23B05 is an enclosed AC-DC switching power supply providing a regulated 5V DC output at up to 60A, with a rated output power of 300W. It accepts the AC or DC input ranges listed below and is designed for integration into finished equipment.
A 5V model rated at 300W with a very high 60A output current, suited to LED displays and large 5V logic loads. The wide 85-305VAC input range suits equipment fed from unstable mains. Built-in active PFC keeps the power factor high and reduces harmonic load on the mains supply. A built-in DC fan provides forced-air cooling; keep the vents unobstructed and expect audible fan noise in quiet environments.
Key Features
- Adjustable DC output (4.5-5.5V) for compatible equipment and control circuits.
- 84% typical efficiency at 230VAC.
- 4000VAC input-to-output isolation test rating.
- Protection against short-circuit, over-current and over-voltage faults.
- Enclosed metal chassis with screw-terminal connections.
- Built-in DC fan (forced air cooling). Allow suitable airflow and installation clearance.

Selection and Installation
Match the output rails to your load, and allow for its continuous current and start-up demand. Follow the manufacturer's derating curves: the maximum output is not available at every input voltage or ambient temperature. Adjusting the output voltage does not increase the permitted output power or current.
This is a component power supply, not a consumer plug-in adapter. Mains wiring should be carried out by a qualified person in a suitable protective enclosure. Disconnect input power before connecting wires, follow the marked terminal assignments and protective-earth requirements, and keep ventilation paths clear. The isolation figure is a test rating, not a continuous operating voltage.
