1kVA sine wave inverters for heavy-duty applications

Measuring 127 mm x 127 mm x 397 mm (5″ x 5″ x 15.6″), the ruggedly constructed CSI 1K–U5515 series feature microprocessor controlled conversion topology and an innovative internal mechanical design. This enables high efficiency, compact construction, low weight and low price.

The inverters provide a single, regulated pure sine wave output of 115Vac/8.7Arms continuous at 400Hz or 60Hz, or 230Vac/4.3Arms continuous at 50Hz. With other input and output voltages available on request, the standard DC-input voltages include 48Vdc (42–56V), 110Vdc (90–130V) or 125Vdc (106–145V). While the input and output have a dual stage high performance filter which ensures low noise, the input meets EN55022 Class A conducted and radiated requirements with wide margins.

Complying with C22.2 No. 107.1-01, UL 458 and EN/UL60950-1 and equivalent internationally recognized industrial safety standards, the CSI 1K–U5515 series feature 1700Vdc input to output isolation (which may differ depending on the voltage requirements), and protection for overload, over voltage, short-circuit and inrush current. Operating over a temperature range of 0°C to +50°C without de-rating, a high quality built-in fan provides sufficient cooling. Extended temperature ranges and conformal coating are available for operation in severe environments. Remote shutdown and an output fail alarm (Form C) are also available on request.
