ABSOPULSE Electronics Ltd. 300VA, Rugged, Compact 3-Phase Railway Quality DC-AC Sine Wave Inverter CTP-300R-F7

3- Phase sinusoidal output voltage EN50155 input ranges For train and mobile applications Filtered input/output Conduction/convectio nn cooled Compact construction Full electronic protection Rugged, field-proven design This rugged railway quality DC-AC inverter uses field-proven, microprocessor controlled high frequency PWM technology to generate the required output power with 3-phase sine wave output voltage. It meets the requirements of EN50155 for electronic equipment used on railway rolling stock. 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 conduction via baseplate. Additional cooling is achieved by natural convection through the cooling slots. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also provides exceptional mechanical ruggedness. Conformal coating provides protection against humidity and airborne contaminants. Full electronic protection, generous design headroom and the exclusive use of components with established reliability also contribute to high MTBF. The unit is manufactured at our plant under strict quality control. An industrial quality version of this design, the CTP-300-F7, is also available.
