MORNSUN Guangzhou Science & Technology Co., Ltd.
Company Overview
MORNSUN (ιει³) is an industrial power supply manufacturer founded in 1998 and headquartered in the Science City area of Huangpu District, Guangzhou. The company describes itself as a one-stop power supply solutions manufacturer, and its 28-year history in power supply design and manufacturing makes it one of the more established domestic players in the power module segment.
Its product line is broad and standardised rather than bespoke, which is typical of the module business: a large catalogue of off-the-shelf DC/DC and AC/DC converters that designers drop into their own equipment. The company states it has introduced more than 6,000 industrial power supply products and serves customers across industrial, medical, telecom and emerging energy applications.
Main Products
- DC/DC converters β the company's founding product line, covering a wide range of input and output configurations.
- AC/DC converters and enclosed switching power supplies β for equipment power.
- Transceivers and signal conditioning modules β isolation and industrial signal products.
- Current sensors and IGBT drivers β power electronics building blocks.
- LED drivers β for lighting applications.
- Products built on newer semiconductor technologies, including SiC and GaN based designs.
Certifications and Quality Systems
The company states it holds ISO 9001:2015 for quality management, IATF 16949 for the automotive supply chain, and ISO 14001 for environmental management. Buyers in medical, automotive or export applications should always request the specific product-level approvals that apply to their market β UL, CE, IEC 60601 for medical β and confirm them against the certificate rather than the catalogue.

What a Buyer Should Know
MORNSUN is the kind of supplier a hardware company uses when it needs a power module that is documented, certifiable and consistently available, rather than the cheapest possible board. The catalogue breadth is the attraction β you can usually find a standard module that fits a design instead of paying for a custom build.
Two practical notes. First, power modules are sold heavily through distributors, and buying through an authorised distributor often gets you better technical support and traceability than buying grey-market stock, which is a real problem in this category. Second, if your end product lands in a regulated market β medical devices, automotive, aviation β verify the specific product approvals yourself against the certificate, and be aware that MORNSUN appeared on the U.S. Treasury Department's Specially Designated Nationals list in May 2024, which is a supply-chain compliance consideration for some buyers.
