Product Specifications
- Operating environment: standard industrial low‑voltage switchgear cabinet
- Contains control unit, PCB connecting terminals and two mounting fasteners
- Provides manual / automatic operation mode selection
- Alarm output function for power‑source fault conditions
- Designed for assembling automatic transfer switch (ATS) solutions
Function
Continuously monitors voltage status of two independent incoming power sources. When the preferred source fails, the unit triggers automatic transfer to the standby power source. It supports manual local operation, status display and fault alarm output, realizing reliable power switching for critical loads.
Purpose
Used to realize automatic power source switching when matched with motorized change‑over switches, preventing power interruption for important electrical equipment.
Application Fields
Data center power distribution, industrial manufacturing plants, commercial building power systems, hospital power supply systems, water treatment facilities, infrastructure low‑voltage switch‑gear cabinets, backup power ATS systems.Image search keyword: ABB OMD300E480C‑A1 control unit
