Description

APC by Schneider Electric E3SUPS40KFBS Concise Descriptor

Overview

The APC by Schneider Electric Easy UPS 3S 40 KVA 208V 3:3 UPS, model E3SUPS40KFBS, is designed to deliver clean, reliable, and continuous power to critical IT infrastructure in commercial and enterprise environments. This 40 kVA unit ensures that sensitive electronic equipment, such as servers, network switches, and storage arrays, remains operational during power disturbances, preventing data loss and system downtime. Its 3:3 power factor and 208V input/output make it suitable for standard US data center rack deployments. This UPS is specifically configured for internal batteries, simplifying installation and reducing the physical footprint compared to external battery cabinets.

Compatibility

This Easy UPS 3S model is designed to integrate with standard IT racks and power distribution units. It is compatible with a wide range of IT equipment requiring stable 208V power, including servers from major manufacturers like Dell PowerEdge, HPE ProLiant, and Cisco UCS, as well as network core switches and storage systems. While not tied to a specific camera or NVR brand, it serves as the foundational power protection for the entire surveillance system's IT backbone, ensuring uninterrupted operation of network video recorders (NVRs), servers running VMS software, and network switches feeding camera data.

Installation Notes

Installation requires a qualified electrician to ensure proper connection to the 208V 3-phase power source and the load distribution panel. Ensure the installation environment meets the UPS's operating temperature and humidity specifications. Proper ventilation is critical to prevent overheating. The unit's internal battery configuration simplifies setup, but ensure adequate clearance for airflow. Torque specifications for electrical connections must be adhered to per local electrical codes and manufacturer guidelines to ensure safety and reliability.
