The D700 is a digital Automatic Voltage Regulator (AVR) for alternators requiring a nominal excitation current up to 25A.
It has been designed for reliable electric power generation, with built-in options and settings to fit any installation, on or off-grid.
The D700 can be controlled through the integrated display or using the builtin webserver interface. It can also be configured through USB without external supply.
It also includes numerous inputs and outputs, and communication ports that match current industry standards.
