High Isolation DIN-Rail Power Supplies from 30W to 120W

August 26, 2019 by Paul Shepard

Mornsun launched a series of high isolation compact size DIN-Rail ac-dc power supplies. The LI120-20BxxPR2 series 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, street lamp control, power grid, security, communications, smart home, and so on.

The LIxx-20BxxPR2 series covers output powers of 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.

LI120-20BxxR2 advantages in the display screen of numerical control tool:

  • Compact size with standard DIN-Rail package, limited space requirement, easy to install
