Product Information
- Designed for Rail applications to EN50155.
- Sinusoidal output waveform.
- Convection cooled No Fans.
- Wide range of input options: 24 ~ 125VDC.
- Optional output fail alarm on some models.
The RSI500 is rugged DC/AC inverter is designed for a variety of Rail applications and designed to meet EN50155.It uses field proven, microprocessor controlled high-frequency PWM technology to generate 500VA output power with pure sine wave output voltage. It is a mature design with a track record in numerous Rail & Industrial 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 unit has full electronic protection. The input and output are filtered for low noise. Cooling is via baseplate to a heatsinking surface and by natural convection.
