Communication & Control Units

For Scada-Mate® and Scada-Mate CX™ Switches

Two versions are available: Self-powered (with a temperature-compensated, constant-voltage battery charger) and externally powered (with a high-output, temperature-compensated, constant-voltage battery charger)

S&C Communication & Control Units are custom-engineered controls specifically designed for use with Scada-Mate Switches and Scada-Mate. They accommodate most user-specified remote terminal units and communication devices, and are generally used in distribution automation and other Smart Grid applications that don’t involve the IntelliTeam.

FEATURES

S&C Communication and Control Units have been extensively tested to ensure reliable operation in the harshest environments. Two versions are available. Communication and Control Unit—Self-Powered features a temperature-compensated constant-voltage battery charger that’s powered by an S&C Voltage Sensor. Communication and Control Unit—Externally Powered features a high-output, temperature-compensated, constant-voltage battery charger with a unique battery management system that’s powered by a user-supplied 120-Vac source.

The custom-engineered CCU includes the following:

• A user-specified remote terminal unit, factory-installed and wired;
• A user-specified communication device, factory-installed and wired, including surge protector for a user-supplied antenna;
• A temperature-compensated constant-voltage battery charger with rechargeable, sealed-lead, starved-electrolyte battery packs, which provide power for charging and tripping the mechanism plus power for the RTU and communication device.
• The charger features integral load-disconnect circuitry to prevent deep-discharge of the batteries on loss of ac source, plus alarms for loss of ac source, battery low voltage, and charger overvoltage. It also includes circuitry to effect a battery load-test feature, when used in conjunction with a suitable RTU.
• In the self-powered version of the communication and control unit — CCU-SP — the battery charger is powered by the S&C Voltage Sensor. The external 120-Vac powered version of the communication and control unit — CCU-XP — features a higher-output battery charger, with unique battery management system.
• A switch control with open/close push buttons, switch-position indicating lamps, disconnect closed and latched indicating lamp, local/remote switch, and operation counter. All components are neatly packaged in a single 316L stainless-steel enclosure, simplifying installation and minimizing checkout time.
