ABSOPULSE Electronics Ltd. 1000VA Railway Quality DC-AC Inverters with Sine Wave Output Voltage, Low-profile RSI 1K-F31

Sinusoidal wave shape Field-proven rugged design Cooling by conduction and natural convection Low profile, compact size Full electronic protection This rugged, railway quality DC-AC inverter series uses field-proven, microprocessor controlled high frequency PWM technology to generate the required output power with pure sign wave output voltage. The units meet the requirements of EN50155 for electronic equipment used on railway rolling stock. The design is based on a mature design topology with a track record in numerous applications. The DC-DC input stage boosts the input voltage to a higher DC voltage, which feeds the DC-AC inverter to generate the required AC output. The use of high frequency conversion enables a compact construction, low weight and high efficiency. The input and output are filtered for low noise. Cooling is by baseplate to a cold plate surface and by natural convection. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also ensures exceptional mechanical ruggedness. Conformal coating provides protection against humidity and airborne contaminants. Full electronic protection, low component count, large design headroom, and the exclusive use of components with established reliability contribute to a high MTBF. All ABSOPULSE products are manufactured at our plant under strict quality control. Industrial quality versions of this design are also available.
