Sinusoidal output voltage
Rugged, field-proven design
Compact, light weight
Conduction/convection cooling
Full electronic protection

This rugged DC/AC inverter uses field proven, microprocessor controlled high frequency PWM technology to generate 50VA low voltage
pure sine wave output. The design is based on mature technology with a track record in numerous applications. The DC/DC input stage
converts the input voltage to a stable DC voltage, which feeds the DC/AC inverter to generate the required AC output. Direct DC/AC
conversion without the use of a step-down transformer simplifies the design and enables compact construction, low weight and
reduced cost. The input and output are filtered for low noise. Cooling is via baseplate to a heat-sinking surface and by natural
convection. Full electronic protection, generous design headrooms and the exclusive use of components with established reliability also
contribute to high MTBF. The unit is manufactured at our plant under strict quality control.
