The CSI4K is rugged DC/AC inverter uses field proven, microprocessor controlled high frequency PWM technology to generate 4000VA 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 on board fans.
