Unipower has launched the Scimitar series of rack-mount sine wave inverters that are designed for applications in telecoms systems.

The Scimitar series is made up of 1U high, 1kVA and 2kVA sine wave inverters designed for 19in rack systems and capable of producing a 115VAC or 230VAC output from a 12, 24 or 48VDC power source.

Each sine wave inverter provides a very low distortion 50Hz or 60Hz sine wave produced by a digital signal processor (DSP) controlled power circuit using an advanced high-frequency, pulse width modulation (PWM) technique, which achieves efficiency levels as high as 92 per cent.

In normal operation these inverters isolate the load from wide voltage swings, transients and noise present in the utility provided AC that can cause reliability problems in systems.

A built-in static transfer switch allows the user to connect a utility or another AC power source, which can then be automatically switched to the load for inverter backup.

Output voltage and frequency can be programmed either from the front panel and the unit’s digital display provides the user with an instant indication of the inverter’s status, which can also be obtained via an RS232 interface.

AC output connections are provided by two Nema 5-15 outlets for the 115V versions and two IEC60320-C13 outlets for 230V versions.

AC output connections are provided by two IEC60320-C13 outlets for 230V versions and two Nema 5-15 outlets for the 115V versions.

All Unipower Scimitar sine wave inverter models meet the requirements of all relevant safety standards including UL60950-1, CSA22.2 No 60950-1 and EN60950-1.

Scimitar sine wave inverters are RoHS compliant.

These 1U high sine wave inverters provide a versatile solution for telecoms systems, particularly those that need a clean low distortion power source.

Typical applications: wireless base stations; central office power; solar and wind power; utility substations; battery backup systems; data centre power and other telecom equipment.
