Dedicated Exclusively to High-Reliability Switching Power Supplies
Founded in Wenzhou, China, MZMW was established with a clear engineering mission: to deliver industrial-grade power supplies that operate consistently in the most demanding 24/7 environments.
Unlike trading companies, our facility encompasses the complete manufacturing chain. We oversee every stage in-house — from automated SMT surface mounting and high-frequency transformer assembly to rigorous 48-slot burn-in aging and oscilloscope parameter verification.
Today, our products power factory automation lines, CNC machinery, LED signage, telecommunication cabinets, and security systems across Europe, the Middle East, Southeast Asia, and the Americas.
