B1205LS-1WR3 Description

Short technical summary and product information.

The MORNSUN B1205LS-1WR3 is a 1W isolated DC DC converter module designed for commercial ITE (Information Technology Equipment) applications. It provides a regulated 5V output at 200mA from an input voltage as low as 10.8V.

 

The module features 80% typical efficiency and is housed in a compact 7-SIP (4-lead) through-hole package measuring 19.7mm x 10.2mm x 6.0mm. It operates over a -40°C to +105°C temperature range (with derating), making it suitable for a wide range of industrial environments.

 

The B1205LS-1WR3 carries safety approvals from CB, CE, cURus, and UL (standard 62368-1). Its isolated design provides galvanic isolation between input and output circuits for reliable power delivery.
