SLI 15 Inverter Series Data Sheet
1500 Watt, 1U Compact Inverters
Description
The SLI 15 Inverter Series provides an ideal solution for telecom, IT, and industrial applications. Due to innovative
technology solutions like the patent-pending "Compact Coil", the SLI 15 inverters pack 1500 watts of power into a
light (5.6 kg) and compact package that is mountable in 19" racks and is only one rack unit high. The SLI 15
Inverter Series offers four models for different input (24 and 48 VDC) and output (115 and 230 VAC) voltage
combinations. An integrated controller, along with an optional internal Static Transfer Switch (STS) enable flexible
and scalable systems which are truly "plug and play", and require no external subsystems. The inverters can be
stacked up to the power level needed by each application and also have the capability to be configured for
generating a 3-phase voltage source.
Electrical performance of the SLI 15 is exemplary of a top-of-the-market product with efficiency that peaks at 93%
and a patent-pending control algorithm that compensates current harmonics on the DC side without using bulky and
expensive filters. The SLI 15 includes a powerful on-board Digital Signal Processor (DSP) that allows easy
programming of main parameters through use of its front-panel keypad and LCD display. In addition, the SLI 15 can
be interfaced with an RS-485 serial communications link.
