Mornsun LO65-10B12 Power Supply
The Mornsun LO65-10B12 is an open-frame AC-DC switching power supply providing a regulated 12V DC output at up to 5.42A, with a rated output power of 65W. It accepts the AC or DC input ranges listed below and is designed for integration into finished equipment.
An open-frame board-level supply: it is designed to be built into a finished product with its own protective enclosure, not used as a standalone adapter. Output voltage is fixed (no adjustment potentiometer).
Key Features
- 85% typical efficiency at 230VAC.
- 3000VAC input-to-output isolation test rating.
- Protection against short-circuit, over-current and over-voltage faults.
- Open-frame PCB-mount construction for integration into finished equipment.
- Free air convection. Allow suitable airflow and installation clearance.

Selection and Installation
Match the output voltage 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.
