1kVA, Low Profile, Railway Sine Wave Inverters Meet EN50155

The RSI 1K-F31 series of railway quality DC-AC inverters deliver up to 1,000VA pure sine wave output voltage.

The series provides a single output of 115Vac continuous at 60Hz or 400Hz, or 230Vac continuous at 50Hz. Input voltages include 24Vdc, 36Vdc, 48Vdc, 72Vdc, 96Vdc, 110Vdc or custom, with wide EN50155 input ranges.

The RSI 1K-F31 inverters meet the requirements of EN50155.  They are equipped with heavy filtering on the input and output and comply with EN50121-3-2. The units meet EN61000-4-2, EN61000-4-3, EN61000-4-4, and EN61000-4-6. They also meet the requirements of C22.2 No 107.1-01, UL 458 and EN/UL60950-1 and equivalent industrial safety standards.

Cooling is by baseplate to a cold plate surface and by natural convection.  This ensures continuous operation over a -25°C to 55°C temperature range for full specification. Wider temperature ranges are available on request.

A version of this design with fully encapsulated internal modules, the RSI 1KP-F31, is also available. The internal modules are potted with a thermally conductive MIL-grade silicon rubber compound for immunity to high levels of shock and vibration as well as to humidity, moisture, dust and other contaminants.

A rugged industrial grade version of this design, the CSI 1K-F31 series, is available for operation in industrial automation, mining, marine, telecom, utility and other heavy-duty environments.

Please contact the company for price and availability.
