CL-7 voltage regulator control

Voltage regulators

Eaton’s Cooper Power series CL-7 voltage regulator control maintains the easy-to-use interface of previous CL controls, but with advanced smart grid features is designed with the future in mind. It comes as standard equipment on Eaton’s Cooper Power series voltage regulators, but can be applied to operate nearly any voltage regulator in service today. This advanced control features single-phase and multi-phase versions that are part of a common control platform – offering a consistent look and feel that lowers training costs through operator familiarity.

This video explains the features and benefits of the CL-7 controller including the CL-7 interface, communication capabilities and multiphase control among other items.

Integrated volt-var compensation benefits

In this video, experts from Eaton's Power Systems Experience Center (PSEC) explain the methods and benefits of integrated volt-var compensation using voltage regulators and power factor correction to optimize voltage quality on utility power systems.

Integrated design and manufacturing

Eaton’s Cooper Power series voltage regulator apparatus and control are designed to operate together, so exclusive features such as Duty Cycle Monitor (DCM), Preventive Maintenance Tapping (PMT) and motor trouble diagnostics are available to alert users to a need for maintenance. Proactive maintenance and quick alerts to impending issues will minimize maintenance costs and system downtimes.

Focus on smart grid

The CL-7 voltage regulator control is communications-ready, with integrated communications interfaces, multiple protocols, battery backup and dc power supply. The CL-7 control is specifically designed for remote operation and retrieval of field measurement data for analysis by integrated volt/var applications.

Multi-phase voltage regulator control

The CL-7 multi-phase voltage regulator control operates two or three voltage regulators to provide a single point of communications, three-phase metering and advanced delta system features. The multi-phase control expands on the intelligence of a single-phase control by adding modular hardware to provide monitoring and control of additional phases without additional controls.

Easy retrofit to most voltage regulators

The CL-7 control retrofits to operate most voltage regulators regardless of manufacturer: Siemens/Allis Chalmers, General Electric, Howard Industries, Reinhausen, ITB, Toshiba, as well as Eaton, Cooper Power Systems and McGraw Edison.

Lower training costs

The CL-7 control employs the same easy to use features of previous CL controls. It utilizes most of the same function codes and all of the same easy-to-use interface features. Field technicians familiar with earlier regulator control models will already know how to use the CL-7 control. This control is part of a common Cooper Power series control platform. The consistent look and feel lowers training costs through operator familiarity with other controls on the platform.
