Pure sine wave 1kVA inverters suit heavy-duty applications



CSI 1K–U5515 series rugged, modular, dc-ac inverter systems

The CSI 1K–U5515 series of rugged, modular, dc-ac inverter systems employ field proven microprocessor controlled high frequency PWM technology to deliver 1kVA sine wave output voltage. They are suitable for a broad range of heavy-duty industrial applications that require “clean”, stable AC-power.

New microprocessor controlled conversion topology and an innovative internal mechanical design enable high efficiency, compact construction, low weight and low price. The ruggedly constructed units measure 127 x 127 x 397 mm (5″ x 5″ x 15.6″).

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. Standard DC-input voltages include 48Vdc (42–56V), 110Vdc (90–130V) or 125Vdc (106–145V). Other input and output voltages are available on request. 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.

The CSI 1K–U5515 inverters comply with C22.2 No. 107.1-01, UL 458 and EN/UL60950-1 and equivalent internationally recognized industrial safety standards. They have 1700Vdc input to output isolation (which may differ depending on the voltage requirements), and protection for overload, over voltage, short-circuit and inrush current. A high quality built-in fan provides sufficient cooling for operation at full specification over a 0°C to +50°C temperature range without de-rating. 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
