UPS 1-3KW RT Lithium

The RT Lithium with its compact design can be used in very limited space. Thanks to the lithium battery, it provides long autonomy times and, with over 2000 charge/discharge cycles, offers an extraordinarily high cycle stability.

The power consumption is almost ideally sinusoidal.
Furthermore, the RT Lithium offers a power factor of 1.0.

With the adjustable current distribution, non-critical consumers can be switched off in battery operation in order to extend the autonomy time.
