Dewar Electronics have available Unipower Telecom’s INV1048 & INV1548 Series 1kVA & 1.5kVA sine-wave inverter modules which are available with 2-unit shelves.

Features of the rack-mount inverters include:

  • The rack mount inverters operate off a 48VDC source and produce a 120 or 230VAC nominal output
  • The inverter system is scalable from 1kVA or 1.5kVA for one module to 18kVA for 12 modules which operate in parallel
  • The low distortion 50 or 60Hz sine wave is produced by DSP controlled power circuits using an advanced high frequency, pulse-width modulation technique which achieves 90% efficiency and 10.5VA per cubic inch power density
  • The shelves on the rack mount inverters are automatically paralleled for higher output power and N+1 redundancy. They are fully isolated from the battery and self-cooled by internal variable speed fans
  • Front panel LEDs indicate inverter status and relay alarm outputs are available on the back of the shelves
  • The Sabre Series rack mount inverters can be operated independently or integrated with a matching Controller and Static Transfer switch as well as a Power Distribution & Maintenance By-Pass unit
  • When the controller is employed a remote communications option provides connection to a PC via USB, RS232 or RS485 serial connections The controller also provides 5 relay alarm outputs that can be programmed for various system parameters
  • SNMP alarm traps (replacing the relay alarms) can also be provided over an Ethernet TPC/IP connection
Typical applications of the rack mount inverters include:
  • Wireless Base Stations
  • Central Office Power
  • AC Appliances
  • Utility Substations
  • Battery Backup Systems
  • Data Centre Power
  • Other Telecom Equipment
