APC NetShelter Rack ATS – Intelligent & cyber-secure for seamless power switching

The APC NetShelter Rack Automatic Transfer Switch (ATS) AP44xxA series is the Fifth-Generation range of high availability switches offering greater control of your IT equipment from Cloud to Edge. With Industry leading reliability, agility, and manageability the APC NetShelter Rack ATS provides redundant power to single-corded equipment loads in the IT rack.

The Rack ATS has been upgraded with the Network Management Card 3 (NMC3) and various other technical advancements for network port sharing, environmental monitoring, and enhanced security. The Rack ATS offers industry-leading transfer time and improved outlet connections to ensure seamless power switching without interrupting the critical loads. Users can access and configure Rack ATS through secure Web UI, SNMP, CLI and are fully compatible with EcoStruxure IT.

This includes a variety of input-output connections in 1 Phase 100/120V, 200/208V, or 230V to multiple outlets ranging from 1440VA to 7440VA allowing users to address the most common power distribution requirements.

Ride-through time & transfer time
• Ride through time is measured in miliseconds (ms) and it is the length of time in which IT equipment can continue to function during a complete loss of power.
• Driven by attempts to improve efficiency, ride-through could be as low as 10-20ms.
• For systems with dual power supplies, increases the ride-through time by as much as 50-100%.
• Since many datacenters have moved to double conversion UPS, shorter cycle time has become the need of the hour.
• This curve indicates that power supplies should be able to withstand 20ms of blackout without interruption in function. The power supply “rides through” this outage
without issue.
• With this in mind, our current Rack ATS specification of a maximum transfer time of 10ms would result in no interruption.

Robust out-of-phase switching
• To prevent relay welding, both hot and neutral lines are switched using a break-before-make system so there is no cross-connection of sources, regardless of the phase between sources.
• AC sources are isolated prior to switching outputs, eliminating the chances of relays welding at contacts
• Sources can be up to 180 degrees out-of-phase

Break before Make switching sequence
Firmware detects that source A is out of the user specified tolerance range. The input power from Source A is removed, then the output is disconnected. This allows for out-of-phase switching and significantly reduces the opportunity for relay welding. Crucial timing is controlled through the firmware (via firmware version 357 or greater)

Break before Make switching sequence

NOTE: Each relay block shown below represents two relays, each breaking individual lines (including neutral).

Source A is providing power to the outlets, while Source B is isolated from the system.

Firmware detects that source A is out of the user specified tolerance range. The input power from Source A is removed, then the output is disconnected. This allows for out-of-phase switching and significantly reduces the opportunity for relay welding. Crucial timing is controlled through the firmware (via firmware version 357 or greater).

Relays are engaged and power is transferred to source B. Total transfer time typically is 8-12 ms.

Key Features

A. Reliability
– Switching time <10ms
The transfer time from one source to the other is seamless to the connected equipment, as the switching occurs safely between the two input sources regardless of any phase differences.
– Field-replaceable NMC
Integrated Network Management Card(NMC)/Display Module can be replaced in the field to minimize downtime disruption in the unlikely event of a failure.
– Temperature and humidity sensor support
Enables you to monitor temperature and humidity in your Data Center or Network Closet.
– Dual input power cords
Supplies power to the connected load from primary and secondary power source i.e If among the two independent sources, the primary source becomes unavailable or out of configurable power range , the Rack ATS will seamlessly switch to draw power from the secondary source without interrupting critical loads.
– 2-years standard warranty and
– 5-years extended warranty
For peace of mind and use for years to come.

B. Agility
– 32 Rack ATS Network Port Sharing(NPS)
Connect and manage up to 32 Rack ATSs from one IP address via one network connection to simplify and speed deployment while saving the cost required in having a dedicated network connection for each Rack ATS.
– Flash Upgradeable
Quickly and easily upgrade firmware via network download for future product enhancements. Eliminates the need to replace products already installed in the field when new features are released.
– APC Wi-fi USB device support
Supports APC Wi-fi USB device for Cableless installation & Setup

Gigabit Ethernet Support
• Improved for today’s faster networks & future-proofed for networks to come.
• Supports faster Communication at 1 Gbps (Gigabit per second) over Network.
• Enhance and standardize network connectivity across all assets in the data center.
• Built-in network connectivity, which allows remote management via Web User Interface (Web UI) its command line interface (CLI) , Simple Network Management Protocol (SNMP), or EcoStruxure Data Center Expert

LCES1 Mini NMC3 Network Management Card
• Color LCD display
• Remote monitoring and control of an individual Rack ATS by connecting it directly to the network
• New Rack ATSs utilize APC embedded Network Management Card 3 (NMC3) with enhanced security features including secured interfaces and a modified password policy providing peace of mind.

EcoStruxure IT Ready
• Seamless integration of one or many ATSs including alerts and control with EcoStruxure IT
• Allows IT and data center professionals to monitor and manage all their critical IT infrastructure on-premise, in the cloud, and at the edge from anywhere alarm notification in the event of an issue.
