This industrial quality DC/AC inverter utilizes field proven, microprocessor controlled high frequency PWM technology to generate the required output power, with pure sign wave output voltage. It is packaged in two watertight, rugged diecast aluminium IP66 enclosures with sealed circular connectors mounted on a 16″ x 13.44″ base plate. Cooling is by conduction via baseplate to a heat-sinking surface and convection via the walls of the IP66 enclosure. The internal inverter unit is fully ruggedized and the boards are conformal coated to provide additional immunity to shock, vibration and humidity.
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 high-frequency conversion enables a compact construction, low weight and high efficiency. The input and output are filtered for low noise. Full electronic protection, low component count, large design headroom, and the use of components with established reliability contribute to a high MTBF. The units are manufactured at our plant under strict quality control.
Customized versions are available. This design is suitable for transportation, mining, marine, oilrig, military and other severe environments.
