The PSI300 is rugged, fully encapsulated product conductive MIL-grade silicon rubber compound, to ensure immunity to shock, vibration and humidity. It uses field proven, microprocessor controlled high-frequency PWM technology to generate 300VA output power with pure-sign wave output voltage.
It is a mature design 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 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.
