Description
The NetSure™ 731 A41 series showcases the new platform's higher power densities, designed to deliver reliable and uninterruptible DC power for the telecom access applications. Up to four 3000W/3500WeSure rectifiers can be accommodated that deliver a system ef iciency of greater than 97.5% and even enable significant energy savings at low loads in the ECO mode. The system's unmatched environmental tolerance and streamlined architecture, combined with intelligent monitoring and controls, make the industry's most reliable DC power systems even more robust.
The NetSure™ 731 A41 series has an integrated standard control unit; alternatively, an advanced unit with enhanced load management capabilities is also readily available. Remote Monitoring and software
updates are available through web browsers with access via multiple gateways, resulting in rapid deployment, upgrades, and efficient service.
