DC-AC Inverters

  • 1.2 kVA Models
  • 2 kVA Models

Our DC/AC inverter that we developed takes advantage of the same technology cultivated in our AC/AC inverter, and provides an insulated sine wave using the secondary battery as an input source. In addition, our inverters can be set up in parallel operation for inverter output and be used in various applications.

1.2 kVA Models

Features

Our DC/AC inverter is used as an input source for the secondary battery. The voltage is first converted in an insulated DC/DC inverter, and then the inverter outputs a sine wave.

DC voltage → step-up or step-down circuit used for DC voltage → AC voltage (constant voltage)

However, our DC-AC inverters can also be set up and used for output parallel operation with our CPU-based digital control.
In addition, the structure of our DC/AC inverter features a solid mold design that is machined according to the usage conditions. It is not only able to withstand dusty or dirty conditions, but also offers high reliability.
