ABSOPULSE Electronics’ has announced the RSI 30-D1 series of railway quality sine wave inverters which deliver 30VA pure sine wave output voltage. The inverters meet the requirements of EN50155 for electronic equipment used on railway rolling stock. They employ microprocessor controlled high frequency PWM technology to convert 24, 48, 72, 96 or 110VDC, with wide EN50155 input ranges, to 115, 230VAC or custom outputs.
With heavy filtering on the input and output, the units comply with EN50121-3-2. They also meet EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-6 and related railway standards.
Installed in IP66-rated waterproof, die cast aluminium packages with sealed connectors, the inverters are protected from the ingress of rain, humidity, sand, dust, metallic dust, oil and other contaminants.
The units are cooled by internal conduction to the walls of the IP66 enclosure and by baseplate and operate within a -25 to 55°C range without derating.
Optional full encapsulation of the internal inverter module in a MIL-grade silicon rubber compound would enable operation within a -40 to 70°C temperature range.
