Dewar Electronics offers Unipower Telecom’s INV1048 & INV1548 Series 1kVA & 1.5kVA sine-wave inverter modules. They are available with two-unit shelves.
These rack-mount inverters are suitable for a number of applications, including utility substations, battery backup systems, data centre power, wireless base stations, central office power, ac appliances, and other telecom equipment.
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.
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
