These inverters provide seamless back-up power for AC powered communications equipment from the site’s 48 or 24 VDC battery system. A fast-acting transfer switch ensures voice and data transmissions remain uninterrupted in the event of a power grid failure or if the site utility power is disconnected for maintenance and upgrade purposes. Built in a 2RU case adaptable for 19” and 23” rack installations.


Features

  • Pure sine wave AC output powers telecom equipment without performance degradation
  • Continuous duty rated – full output wattage maintained even during extended power outages
  • 1000 VA and 2000 VA models available – easily cascaded for N+1 redundancy, providing maximum reliability
    required by data centers
  • Low EMI and RFI interference characteristics
  • User-friendly Status and Diagnostic LCD/LED displays
  • Utility bypass function with fast load transfer switch
  • Remote Power Management optional via RS-232 port
  • Optional SNMP card
  • Numerous circuit and load protections – over-current, over- temp, overload, reverse polarity, high/low battery
    voltage
  • Form C alarm contacts for monitoring AC “Fault” and “DC Abnormal” conditions
  • Adapts for 19” or 23” racks; occupies only 2 RU (3.5”)
  • UL and cUL listed
