EPEPRO EPM3 Series Dual Power Automatic Transfer Switch (ATS)
The EPEPRO EPM3 Series Dual Power Automatic Transfer Switch is a compact and intelligent power transfer device designed for residential, commercial, and light industrial applications. It continuously monitors the main power supply and automatically switches to the backup power source whenever the primary supply fails, ensuring uninterrupted power delivery to critical loads.
Featuring a fast transfer time of less than 50ms, the EPM3 Series provides reliable power continuity while protecting connected equipment from unexpected outages. The switch supports both utility power and photovoltaic (PV) systems, making it an ideal solution for solar energy installations, backup generators, distribution cabinets, and automatic power management systems.
Designed for DIN rail mounting, the compact structure saves installation space and simplifies wiring. The device supports both manual and automatic operation modes, offering flexibility for maintenance and emergency situations.
