Leroy Somer Voltage Regulator D700 AVR

 

Origin: France

Brand: Leroy Somer

Model: D700

 

The Leroy Somer D700 AVR 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 Leroy Somer AVRcan be controlled through the integrated display or using the builtin webserver interface. It can also be configured through USB without external supply.

 

The Leroy Somer D700 Voltage Regulator also includes numerous inputs and outputs, and communication ports that match current industry standards.
