FranMar International

What FranMar International does

FranMar International Inc. is a Taiwan-based private manufacturer of switching power supplies, founded in 1997 and headquartered in Xizhi District, New Taipei City. The company designs, produces and sells a broad portfolio that spans medical and standard AC/DC adapters, AC/DC open-frame and enclosed power supplies, DC/DC converters (including harsh-environment, railway and brick-type variants), battery chargers, LED drivers, DC/AC inverters, and newer categories such as AC/DC bidirectional inverters and MPPT solar controllers. Core technology is built around switching power conversion, including GaN-based fast chargers, fully digital bidirectional power architectures with energy recycle (BIC-2200: 2.2KW, 93% efficiency, 1ms AC/DC–DC/AC switchover), and active current-sharing modules supporting up to 11kW in 4+1 parallel configurations.

The business sells primarily B2B to OEMs in medical equipment, industrial automation, railway, battery manufacturing/test, and renewable/green energy applications, supported by global safety certifications (UL, TUV, CB, CE, CCC, PSE) and a 13-language multilingual website. Revenue is generated through two streams: catalog hardware sales of standard products and customized/ODM modification services billed on an inquiry basis with multi-year contracts and minimized NRE charges. Go-to-market is direct, sales-led and inquiry-driven with no disclosed public pricing. The company operates worldwide and positions itself on technical depth, certification coverage and a 'small number of diverse' customization model rather than commodity volume.
