Mornsun LI75-20B24R2S 24V 3.2A Power Supply
The Mornsun LI75-20B24R2S is a single-output AC-DC switching power supply delivering a regulated 24V DC output at up to 3.2A, 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.
Its narrow 32mm body is designed for rail-mounted control cabinets where space is limited.
Key Features
- Adjustable 24V DC output for compatible equipment and control circuits.
- 89% typical efficiency at 230VAC.
- 4000VAC 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.
