Mornsun LM35-20B24 24V 1.5A Enclosed Power Supply
The Mornsun LM35-20B24 is a single-output, enclosed AC-DC switching power supply in the LM35-20B series. It provides a nominal 24V DC output at up to 1.5A, giving this model a rated output of 36W. Its universal 85-264VAC input also accepts 120-370VDC through the same input terminals.
The ventilated metal enclosure and screw-terminal connections suit installation inside industrial control equipment, security systems, LED equipment and automation panels. Cooling is by natural air convection. This is a component power supply for integration into finished equipment, not a fully enclosed consumer plug-in adapter.
Key Features
- Single regulated 24V DC output, rated at 1.5A / 36W.
- Output voltage adjustment from 21.6V to 28.8V.
- Universal AC input, with AC and DC input sharing the same terminals.
- 88% typical efficiency at 230VAC and standby consumption up to 0.3W.
- 4000VAC input-to-output isolation test rating.
- Short-circuit, over-current and over-voltage protection.
- Metal case with free-air convection cooling and a power-on LED indicator.

Installation and Selection Notes
Allow ventilation around the supply and follow the manufacturer's load-derating curves at high temperature or low input voltage. Full rated output is not available under every input and ambient condition. The metal case must be connected to protective earth. Disconnect input power before wiring; this product is not intended for hot plugging. Mains wiring and installation should be carried out by a qualified person in a suitable protective enclosure.
Check the load's voltage, continuous current and start-up demand before selecting a supply. The 4000VAC figure is an isolation test rating, not a permitted continuous operating voltage. Final equipment must be assessed for its own safety and EMC requirements.
Certification Note
Mornsun's current LM35-20B series page states that its UL certification after May 1, 2024 is currently invalid. Do not select this item on the assumption that it has current UL certification; confirm the exact approvals needed for your project before purchase.
