Description
The CL-7 voltage regulator control from Eaton's Cooper
Power series incorporates the latest in digital technology
to provide accurate, rapid, and dependable control of a
step-voltage regulator. Utilizing surface-mount technology
and low-power electronics, the CL-7 control is CE
(Commonwealth Europe) compliant. The nameplate located
on the control box defines the power circuit.
The CL-7 control provides the first of its kind single- or
multi-phase voltage regulation utilizing a single control
platform. During every step of develop, focus was placed on
producing a control to meet the growing demand for smart
grid ready features and for flexibility to meet the needs
of the future. While great effort was put into enhancing
its features, the CL-7 control remains true to its roots by
maintaining the ease of use of its predecessor CL controls.
The control features the same look and feel of the earlier
controls and whenever possible, the same function codes
were utilized. The CL-7 control allows keypad programming,
Metering-PLUS™ status inquiries, USB memory device
uploading and downloading, and multiple communication
ports with user-selectable protocols of DNP3 (serial and
IP), IEC 60870-5-101 and -104, Cooper 2179, Modbus RTU,
Modbus TCP. LED indicators provide instant information on
alarm, communications, and regulation condition status. A
four-line display provides detailed information and further
simplifies programming. In addition, the CL-7 control is
highly configurable and ready for use in applications where
either digital or analog SCADA is required.
