MORNSUN launched a high isolated compact size DIN-Rail power supply LI120-20BxxPR2 series, which is designed to supply low-voltage bus power supply for control cabinet systems with internal rails for industrial control, new energy, petrochemical metallurgy, railway, DC charging piles, etc. Till now, the LIxx-20BxxPR2 series covers output power 30W, 60W, 100W, 120W and offers output voltages of 5V, 12V, 24V and 48V.

LI120-20BxxPR2 series features 4000VAC isolation test voltage and withstand 300VAC surge input for 5s. EMC meets the requirements of IEC61000 Class 4 and EMI(without peripheral components) meets the standards of CISPR32 Class A. It also meets IEC/EN/UL62368, IEC/EN/UL60335, GB4943 and UL508 safety standards. In addition, it can be installed in 5000m altitude environment. Protections of output short circuit, over-current, over-voltage, over-temperature are included.


Widely used in applications of industrial control, LED, street lamp control, power grid, security, communication, smart home, etc.
