LS05-13B05R3
Mornsun LS05-13B05R3 AC-DC power module, 5 W, universal 85-305 VAC input, 5 V output, 3600 VAC isolation in SIP.
The LS05-13B05R3 is a Mornsun LS series AC-DC power module rated at 5 W with a universal 85-305 VAC input (or 100-430 VDC on the same terminal) and a regulated 5 V output at 1 A, in a compact SIP package. The universal AC input accepts either AC or DC voltage, which simplifies the design and the sourcing, and the module provides reinforced isolation of 3600 VAC between the primary and secondary, which suits industrial and household equipment. The LS series is a highly efficient green-power range with low no-load power consumption and output short-circuit and over-current protection, and the operating ambient temperature range is -40 °C to +85 °C. The compact SIP package mounts directly on the printed circuit board, and the module meets the IEC/EN/UL 62368 safety standard and the IEC/EN 61558 and IEC/EN 60335 standards. Typical applications include industrial control, electric power, instrumentation and smart home devices that have a high requirement for dimension. Every module BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the module, size the front-end protection and filter and plan the thermal design.
FAE Professional Review
The LS05-13B05R3 is the compact on-board AC-DC module we recommend when a small isolated 5 V rail is needed directly from the mains, and the board space is tight. The SIP package and the 3600 VAC reinforced isolation make it easy to use, but keep the input fuse and MOV close and follow the recommended input filter for EMC. It is a very common fit for smart home and instrumentation designs.

Frequently Asked Questions
What projects suit the LS05-13B05R3?
It suits compact designs that need a small isolated 5 V rail directly from the mains, such as smart home devices, instrumentation and industrial control boards. The SIP package and universal AC input make it easy to design in.
Add a suitable input fuse and MOV for protection.
Does it accept DC input too?
Yes. The same terminal accepts 85-305 VAC or 100-430 VDC, so the module works from an AC mains or a high-voltage DC rail with no change. This dual-use simplifies the design and the sourcing.
Confirm the range against your worst-case input.
Is the module genuine and documented?
BeiLuo supplies factory-traceable LS05-13B05R3 modules with an import declaration, certificate of origin and RoHS file on every order. Stock is normally available and the datasheet downloads from this page.
