Digital Voltage Regulator



The D700 is a digital voltage regulator for brushless alternators with continuous field support of up to 25A.

A combination of accurate regulation and embedded features allows the user to easily integrate with a multitude of generator set applications. 
Numerous inputs and outputs can be configured to perform basic logic functions using the EasyReg Advanced software. 
The D700 can be configured via on-board control panel, or with a USB or Ethernet link. Additional communication protocols available via optional additional hardware.
