Rackmount Telecom
DC-AC Inverters
These rackmount telecom DC-AC power inverters provide seamless back-up power for AC powered communications equipment from the site’s 48V or 24V DC 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, CE marked, and RoHS Compliant
