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.
