Robust Core Technology

Maha holds a decisive advantage by having the ability to design its own microcontrollers. This core technology allows Maha to quickly respond to market demands with never-before-seen features.

Market and Technology Driven R&D

Maha undertakes two distinct routes in product research and development: market and technology driven. As an active player in the market, Maha's product management teams constantly listen to customer's feedback and design products to address their needs. On the other hand, Maha also invests strongly to improve fundamental technology in order to enhance performance and reduce cost.

Above-and-Beyond Safety

Maha meets and exceeds safety requirements regulated by agencies such as UL, CE, GS, C-Tick, PSE, etc. In many of the products, customers can expect multiple-redundant safety protections. 


Design robustness is verfied through accelerated life testing such as 25G HALT with thermoshock from -40 to 80 deg C.

Production & Testing

Every Maha product is tested individually by various automated testing systems eliminating the human factor in quality control. All products also undergo a rigorous burn-in/cycling sequence. Random sampling of in-production goods are subject to additional stringent reliability and aging tests.
