■ On-line or off-line mode selectable

■ Meets UL, cUL, and CE requirements

The SLI Family of “Slim Line” inverters represents
an ideal solution for telecom and industrial
applications. Thanks to innovative technology
solutions like the patented “Compact coil” these
inverters pack 1500 VA of power into a small and
light package 19” or 23” rack mountable and just 1
rack unit high. The efficiency peaks 93%.

The family includes 4 models for different inputs
(24Vdc and 48Vdc) and output (115Vac and
230Vac) voltage combinations. Several options
are available for internal Static Transfer Switch

(STS), parallel hot-swap operation to realize
flexible and scalable systems, grid connectivity for
Distributed Generation systems with control of the
power exchanged with the grid, and extended
communication features.

The inverter carries on-board a powerful DSP
(Digital Signal Processor) and allows easy
programmability of the main parameters by means
of an LCD display and keypad on the front panel.
The unit can be interfaced with RS485 or optional
CAN bus to an external controller.
