[MPDU]
Our Main Power Distribution Units (MPDU) are engineered for high-precision semiconductor environments, providing stable power delivery, real-time monitoring, and enhanced safety protection.
Each unit is equipped with Emergency Off (EMO), smoke detectors, door interlocks, and communication functions that transmit real-time status updates to both Process Module (PM) and Power Controller (PC) systems, ensuring maximum equipment uptime and operator safety. We can also supply the power box for semiconductor devices.
[UL67 & UL891]
Our UL67 Panelboards and UL891 Switchboards deliver reliable and flexible power management solutions for residential, commercial, and industrial installations.
They are designed and manufactured under strict UL and ISO-certified quality control systems (ISO 9001, 14001, 45001, 22301, 37301), ensuring long-term durability and compliance with global standards.
Beyond product supply, EMI is committed to providing customized engineering, enclosure design, and integration services that reflect each customer’s operational environment.
We take pride in supporting customers throughout every stage—from initial concept and design to on-site commissioning and after-sales service—establishing long-term partnerships built on reliability and trust.
Certified for global export, EMI’s UL-approved products are widely applied in semiconductor, data center, energy, and automation industries, contributing to a safer and more sustainable technological infrastructure.
