Megmeet successfully developed a continuous aerogel device for the preparation of "aerogel insu

Wavelane successfully developed a continuous aerogel device for the preparation of "aerogel insulation felt". Aerogel felt is a kind of flexible thermal insulation material which is made of silica aerogel as the main material and is compounded in reinforcing fibers, such as glass fiber and pre-oxidized fiber.

Megmeet Obtains the First 30kw DC charging module product certificate CE Certification in the World

TüV issued China's first DC charging module product certificate for Shenzhen Megmeet Electrical Co., Ltd., it is also the first CE certificate of 30kW charging module in the world.

Megmeet Medical Power supply fully meet the world's most stringent standards

Megmeet medical power supply, using the current leading energy-saving technical standards, fully meet the world's most stringent standards for energy efficiency VI, no-load standby power consumption is low, adapters are widely used in mobile b-ultrasound, monitoring, oxygen generator, ventilator, infusion pump and other medical equipment: All series of products have passed the test of IEC60601 standard process, and have obtained relevant safety regulations and EMC certification;Gained the global well-known customer's comprehensive recognition, especially in the north American market, has the good brand effect; The production factory has passed ISO13485 certified by SGS, and the development process is strictly based on EVT/DVT/MVT product development and verification, and the product has a low production defect rate.Long shelf life and low failure rate;Low leakage current, large redundancy and high reliability 1、MEDICAL SURGICAL BED REQUIREMENT
