MORNSUN is a well-known domestic manufacturer of modular power supplies and isolated communication components. Its product portfolio covers isolated DC-DC power modules, non-isolated voltage regulators, isolated RS485/CAN transceivers and more. Featuring high stability and excellent anti-interference performance, MORNSUN products are widely adopted in industrial automation, power meters, smart home, rail transit, medical equipment and other applications. It is a popular domestic brand of power and isolation components frequently selected in electronic hardware BOM design.
The B series is MORNSUN’s classic miniature isolated power supply with power rating from 1W to 2W. Compact in size, it provides on-board isolated power supply for signal isolation circuits. It includes variants such as B0505S, B0505XT and B0505LS. Different suffixes stand for package type, temperature grade and reliability version. F series, IB series and CF series also belong to low-power isolated modules with pin-compatible designs, optimized for different isolation specifications and reliability requirements. They are commonly used in sensors and small-signal isolation circuits.
The K78 series is high-efficiency non-isolated step-down regulators, which can directly replace traditional linear LDOs. They deliver high conversion efficiency without heat sinks and come with built-in short-circuit protection. Output current ranges from 0.5A to 2A. K7803 and K7805 are the most widely used models, offering prominent cost advantages for simple on-board power conversion.
URB, VRB, WRB and WRA series cover power range from 3W to 20W, supporting 24V wide input voltage. They integrate over-current, short-circuit and over-temperature protection with high isolation voltage. URB is the standard general version; VRB is high-reliability variant; WRB/WRA support dual output channels. They are widely used for power supply of industrial control boards and IoT terminals.
TD series integrates isolated power supply, bus transceiver and ESD protection in one single device. It is divided into isolated RS485 and isolated CAN types. TDA51S485HC and TD301D485H are isolated RS485 models; TDA51SCANHC and TD541SCANH are isolated CAN transceivers. A single component realizes dual isolation of power and signal, greatly simplifying PCB peripheral circuits and reducing EMC design challenges.
Devices such as SCM3725ASA are power management ICs for power system monitoring and protection. They are often matched with MORNSUN power modules in BOM design.
