NES Energy Stations

General Description

The Nicotra NES150 family Energy Stations are designed to satisfy the typical requirements for 48 Vdc powered equipments for:

• Telecom Access Nodes
• Base Stations
• Networking Equipment

When AC supply is present, the system ensures a stabilized and filtered DC supply to the loads as well as the full efficiency of the back-up batteries. In case of AC mains fault the system ensures the loads supply from batteries, without interruptions. NES 150 stations are based on the concept of modularity to meet upgradeability and flexibility requirements.

General characteristics

The System is entirely managed by a microprocessor System Control Unit (SCU), which concurrently monitors all the operating steps of the paralleled rectifiers, signals the failures and manages all the parameters and the operating thresholds of the system. The whole configuration is software upgradeable.

• High frequency Switching technology
• Single or three phase input
• Electronic stabilization
• Input EMI protection filter
• LVD (Load Voltage Disconnection) device for the total user load disconnection to prevent the deep discharge of the batteries.
• TCP/IP with SNMP remote management
• Auxiliary 230 Vac plug
• Comply with CE - Standard
• Compact size
• Possibility of internal sealed lead batteries
