FAQ
What is the purpose of an automatic transfer switch in a rack environment?
An automatic transfer switch provides power redundancy by automatically switching between two independent power sources when the primary source fails. This ensures continuous operation of critical IT equipment like servers, storage, and networking gear during power disruptions, minimizing downtime in data center and server room environments.
What power specifications does the AP4434A ATS support?
The AP4434A operates at 208 volts AC with a 20-amp current rating. It accepts dual input power through C20 connectors and distributes power through eight C13 and one C19 output receptacles. The unit is designed for 50/60Hz power systems commonly found in North American commercial and data center environments.
How quickly does this ATS switch between power sources?
This automatic transfer switch achieves seamless power transfer within 10 milliseconds. This rapid switching time minimizes disruption to connected equipment, ensuring servers and network devices maintain operation without rebooting or experiencing significant power interruptions during source transitions.
What management capabilities does the integrated NMC3 provide?
The APC Network Management Card 3 (NMC3) offers comprehensive monitoring and control through web interface, SNMP, command-line interface, and EcoStruxure IT Expert software. It enables remote management of power status, temperature, humidity, and transfer events, while supporting enhanced cybersecurity features for secure network integration.
How many rack units does this transfer switch occupy?
The AP4434A has a 1U form factor, occupying one rack unit of vertical space in standard 19-inch racks. With dimensions of 1.73 inches high, 17.01 inches wide, and 9.29 inches deep, it provides power redundancy without consuming excessive rack space, making it ideal for high-density server environments.
