Mornsun LMF75-23B48 Power Supply
The Mornsun LMF75-23B48 is an enclosed AC-DC switching power supply providing a regulated 48V DC output at up to 1.6A, with a rated output power of 76.8W. It accepts the AC or DC input ranges listed below and is designed for integration into finished equipment.
This model is rated at 76.8W, slightly above the 75W series name. 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.
Key Features
- 4000VAC input-to-output isolation test rating.
- Protection against short-circuit, over-current and over-voltage faults.
- Enclosed metal chassis with screw-terminal connections.
- Free air convection. 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.
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.
