Mornsun LM200-10B12 12V 17A Power Supply
The Mornsun LM200-10B12 is a single-output AC-DC switching power supply delivering a regulated 12V DC output at up to 17A, with a rated output power of 204W. It accepts the AC or DC input ranges listed below and is designed for integration into finished equipment.
Its AC input range is selected by a switch: 90-132VAC or 180-264VAC. For DC operation the manufacturer specifies the 230V switch position. Check the selector before applying input power.
Key Features
- Adjustable 12V DC output for compatible equipment and control circuits.
- 87.5% typical efficiency at 230VAC.
- 3000VAC input-to-output isolation test rating.
- Protection against short-circuit, over-current, over-voltage and over-temperature faults.
- 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. 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.
