1.5KVA INVERTER – SLI15 SERIES

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 1.5kVA Inverter 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 1.5kVA Inverter 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.

Features & Options
24V or 48VDC Input
115VAC or 230VAC Output
New, compact design: 1U height x 19” width x 14.94” depth; 19” rack-mountable
High efficiency: up to 93%

Front panel LCD display to monitor and set the main parameters
RS-485 serial link
Constant input current sink from battery for extended life
Optional hot-swappable configuration
Optional internal Static Transfer Switch
In the -STS version, ON line (primary source to the load) or OFF line mode (UPS like)
Configurable for being used as Three Phase source, 3 units

5KVA INVERTER – SLI50 SERIES

The SLI50 Series 5kVA inverter provide an ideal solution for telecom, IT and industrial applications. Due to innovative technology solutions like the patent-pending “Compact Coil”, the SLI50 Series 5kVA inverter packs 5000 watts of power into a compact package that is 19” rack mountable and only two rack units high.

Electrical performance of the SLI50 Series 5kVA inverter is at the top of the market with efficiency that peaks at 3% and a patent-pending control algorithm that compensates current harmonics on the DC side without using bulky and expensive filters. The inverter includes an on-board powerful Digital Signal Processor (DSP) that allows easy programmability of the main parameters on the front panel LCD display and keypad.

The SLI50 Series 5kVA inverters can be interfaced with RS485.

Features & Options
48VDC Input
230VAC Output
