SLI15 SERIES INVERTERS P O W E R I N G 1U x 19" | 24V or 48VDC INPUT 115 or 230VAC | 1500W OUTPUT T E C H N O L O G Y DESCRIPTION The SLI15 Inverter Series provides an ideal solution for telecom, IT, and industrial applications. Due to innovative technology solutions, the SLI15 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 SLI15 1.5kVA 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 up to a maximum of 6 units and also have the capability to be configured for generating a 3-phase voltage source. Electrical performance of the SLI15 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 SLI15 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 SLI15 can be interfaced with an RS-485 serial communications link and this in turn can be interfaced with most Aspiro and Guardian DC Power Systems using a translator board.

It can be internally installed in systems using the 4U distribution module such as the Guardian Access 5U/6U and cabinet systems. When deployed with an Aspiro or Guardian 2U or 3U system it has to be separately mounted.

When ordered for retrofit or as an accessory it comes as a kit including all required cables (See the ordering guide on page 7). Generating a 3-phase Y voltage It is possible to generate a 3-phase voltage by connecting either 3 or 6 inverters into a Y configuration. The adjacent diagram shows an example of the necessary connections. Note that 3-phase configuration needs to be enabled in the "service" menu.
