Sinusoidal output voltage
Rugged, industrial quality
Cooling by high quality internal fan
Compact construction
Full electronic protection
Cost-effective construction

This rugged, modular DC/AC inverter system uses a field proven microprocessor controlled high frequency PWM technology to generate
1000VA output power with pure sine wave output voltage. The inverter is built with two internal power modules. The DC/DC input stage
boosts the DC voltage which feeds the DC/AC inverter to generate the required AC output. The input and output have a dual stage high
performance filter which ensures low noise. The high frequency conversion enables a compact construction, low weight and high
efficiency. This compact version of the CSI 1K measures 5” x 5” x 15.6”. The innovative mechanical construction significantly reduces the
cost of production and price. This inverter design is only available with terminal blocks for the input and output. Cooling is by a high
quality built-in fan, which draws air into the unit and the exhaust exits at the terminal side of the unit. Full electronic protection,
generous design headroom and the exclusive use of components with established reliability contribute to high MTBF. The unit is
manufactured at our plant under strict quality control.
