STUDER Innotec Xtender

6 Description and functioning

The Xtender is a sine wave inverter with a battery charger. It has been developed for use as a stand- alone installation to supply AC voltage (not connected to the grid) or as a continuous supply.

6.2 Description of the main functions

6.2.1INVERTER

The Xtender is equipped with a high-performance inverter which supplies a perfect and very precise sine wave. Any unit designed for the 230 V/50 Hz electrical grid may connect to it without any problem, up to the rated power out of your Xtender. The inverter is protected against overloads and short-circuits.

Thanks to the largely over-dimensioned performance level, loads of up to three times greater than the Xtender’s rated output can be faultlessly supplied for short periods of use, thus allowing motors to be started up without any problem.

When the Xtender is operating the LED “ON” (43) is glowing.

When the Xtender is in inverter mode, the LED “AC out” (46) is glowing. If it flashes, the inverter is in “load search” mode (see following chapter “Automatic load detection”).

6.2.2AUTOMATIC LOAD DETECTION

In order to save battery energy, the Xtender inverter stops and automatically goes into load search when the detected load is lower than the sensitivity set by the configuration {1187}. It automatically goes back into operation when a power consumer greater than this value demands it. The indicator

(46)flashes if the inverter is in “load search” mode, which also indicates that the AC voltage is present at the output in an intermittent form.

The detection threshold for the absence of loads can be adjusted according to the configuration
