VarCom Communications Controls

The VarCom® Series of Capacitor Controls with ComFlex® allow the user the option of deploying controls with communications factory installed, or the option of deploying the control initially as a local control and later upgrading it with communications. VarCom controls are based on the popular NoMax® Capacitor Control design, which features a best-in-class local control user interface, while also allowing for the addition of communications.

Communications equipped VarCom Capacitor Controls add new capabilities for monitoring and controlling capacitor banks.  Using ComFlex Flexible Communications Technology, communications can be added to any of the VarCom controls.  ComFlex adds command and control functions while maintaining all of the features and capabilities for a full function VarCom control.

Communications technologies include paging, cellular and other radio options: 

  • Basic one-way VHF/UHF communications using radio, pager, etc.

  • Two-way options using any DNP 3.0 communications interface such as cellular or 900MHz

HDE’s DNPFlexSM Control Configuration Solution provides the user with a feature rich standard DNP points list that and a path to create a custom DNP interface to optimize compatibility with existing SCADA control systems or related hardware.
