300VA, Rugged Railway Quality Sine Wave Inverter
Absopulse Electronics’ RSI 300 Series railway quality, DC/AC inverter uses field proven topology to generate a 300VA pure sign wave output voltage. It meets all relevant railway standards including EN 50155, EN50121-3-2 conducted and radiated EMI, EN 55022 Class B, and EN 61000 immunity. This microprocessor-controlled high frequency PWM design delivers 115Vac continuous at 60Hz or 400Hz, or 230Vac continuous at 50Hz, regulated to a maximum of +/-2% from no load to full load. It accepts supply voltages of 24Vdc (14.4-34V range), 36Vdc (22-51V range), 48Vdc (29-67V range), 72Vdc (43-101V range), 96Vdc (58-135V range) or 110Vdc (66-154V range). Other input and output values are available on request. An optional output Fail Alarm (Form C) is also available for this design. The RSI 300 unit operates over a -25°C to +50°C cold-plate temperature range without derating. Cooling is via baseplate to a heatsinking surface and by natural convection. High frequency conversion enables compact construction, low weight and high efficiency. The unit is housed in compact 153 x 67 x 357 mm vented chassis-mount enclosures and weighs 2.2 kg. Ruggedizing and conformal coating ensures resistance to shock and vibration (meets EN61373/IEC61373), moisture and airborne contaminants. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The unit has 3kVdc input to output isolation; it unit features full electronic protection including inrush current limiting, reverse polarity protection, output current limiting with short-circuit protection, thermal shutdown with automatic recovery in case of insufficient cooling. For detailed specifications, please see datasheet above (right). Absopulse offers a wide range of DC/AC inverters designed for operation in railway and other extreme environments. Our designs can be modified to meet customer electrical and mechanical requirement. For datasheets please see here. Return to the Press Release Index page. October 2010. |
