Overview
The APC AP4433A NetShelter Rack Automatic Transfer Switch (ATS) is designed to provide redundant power to single-corded IT equipment. It uses two independent power inputs and automatically switches connected equipment to the alternate source when the preferred source becomes unavailable. Its compact 1U rack-mount design suits data centers, server racks, and network infrastructure environments.
Key Features
- Automatic transfer switching for improved power availability.
- 208V AC single-phase operation with a 12A current rating.
- 3300VA load capacity.
- Two IEC C14 power inlets and twelve IEC C13 outlets.
- 1U horizontal rack-mount form factor.
- Transfer time as fast as 10ms under high-sensitivity conditions.
- Network management, environmental monitoring, and remote administration features.
- Black finish with mounting hardware and serial configuration cable included.
