Overview
- The APC NetShelter AP4423A is a fifth-generation automatic transfer switch designed to provide redundant power distribution across IT racks. It automatically switches between two independent 230V/16A power sources, eliminating single points of failure for equipment connected via single power cords. With a 3700VA capacity and nine output sockets, it supports mixed equipment types from standard servers to high-power devices requiring 16A circuits.
Integrated APC NMC3 network management enables remote monitoring, control, and alerting without requiring additional hardware. The switch supports connection to environmental sensors such as the AP9335T and AP9335TH, allowing comprehensive rack-level monitoring of both power and environmental conditions. This makes it ideal for organisations seeking to combine power redundancy with intelligent infrastructure management.
The compact 1U form factor fits seamlessly into standard server racks, and dual-frequency operation (50/60Hz) ensures compatibility with global power environments. Rated for operating temperatures from -5°C to 45°C and featuring robust IEC connectors, the AP4423A is built for reliable operation in demanding data centre and server room environments.

FAQs
What is an automatic transfer switch and why do I need one?
An automatic transfer switch (ATS) provides redundant power distribution by switching between two independent power sources. It's essential for organisations running single-corded IT equipment that cannot tolerate downtime. If one power source fails, the ATS automatically switches to the secondary source without interrupting power to connected devices.
How many devices can the APC AP4423A support?
The AP4423A has nine output sockets: eight IEC C13 outlets (10A each) and one IEC C19 outlet (16A). The total load capacity is 3700VA, so the number of devices depends on their power consumption. C13 outlets are suitable for standard servers, whilst the C19 outlet accommodates higher-power equipment.
Does the AP4423A require a separate management interface?
No. The AP4423A includes an integrated APC NMC3 (Network Management Card), which provides built-in remote monitoring, control, and alerting capabilities via your network. This eliminates the need for additional management hardware.
Can I monitor temperature and humidity with this switch?
Yes. The AP4423A is compatible with APC environmental sensors such as the AP9335T and AP9335TH. These sensors connect to the management interface and provide real-time temperature and humidity monitoring for your rack.
What input voltages and frequencies does the AP4423A support?
The AP4423A is rated for 230V AC, single phase, with a permissible input voltage range of 207–253V. It supports both 50Hz and 60Hz frequencies, making it suitable for deployment in different regions worldwide.
Is the AP4423A easy to install in a standard server rack?
Yes. The AP4423A is a 1U rack-mounted device and comes with mounting hardware and brackets. It fits into any standard 19-inch server rack. Installation is straightforward and typically requires no specialist tools.
What is the warranty period for the AP4423A?
The APC NetShelter AP4423A comes with a 24-month manufacturer warranty, covering defects in materials and workmanship.
