  • Power shelf for battery back-up
  • Up to 4000W output power
  • Fits in a 300mm deep cabinet
  • Battery backup connections and management
  • Very easy integration in TNM systems
  • Full open interface, ETSI ES 202 336 compliant
  • Ethernet and USB interface


With more than 3000W redundant power on a 19" 1U shelf that fits in a 300mm (11.8'') deep cabinet, this system is the perfect answer to the growing number of applications where space is a constraint. This performance is the result of years of experience shared by the engineering teams with their colleagues from field service and operations to design superior power density without any compromise on reliability.
This power rack of Alpha Innovations is the perfect answer to all power requirements in the 850W to 4000W range. The system encompasses locations for four hot-pluggable rectifiers. The system can be equipped with an embedded monitoring unit offering all essential functions and can be upgraded at any moment with battery management functions and even a communication card for remote control through TCP/IP. The communication offers unrivalled functions supporting XML, SNMP, webserver, FTP, all in compliancy with international standards.
The MCU (Monitoring and Control Unit) supports all the necessary telecom energy monitoring and control functions at the lowest initial investment. It can be upgraded at any time of the life cycle by the features-rich Comp@s card, supporting XML, SNMP, FTP and web based services enabling a virtually infinite opportunity to put sites and networks under perfect control.
Delivered with a temperature sensor, the system features voltage compensation in regard to the battery temperature, protection against deep discharge, battery charge current limitation and regular capacity testing. The system features protection against reverse polarity connection and a user-controlled battery charge current limitation.
This solution can be configured to support NiMh batteries from ARTS Energy.
