Switch Controls and Switch Operators
Communication and Control Units
Communication and Control Units accommodate a wide range of automation approaches and strategies for S&C’s overhead Distribution Automation products. These custom-engineered devices can accommodate most user-specified remote terminal units and communication devices. The following features are standard:
- Switch control with open/close push buttons, switch-position indicating lamps, disconnect closed and latched indicating lamp, local/remote switch, operation counter
- Integral load-disconnect circuitry to prevent deep discharge of batteries on loss of ac source, plus alarms for loss of ac source, battery low voltage, or charger overvoltage. Battery-load test feature works in conjunction with suitably equipped RTUs
- Rechargeable sealed-lead starved-electrolyte battery packs.
They are available in two versions:
- Self-Powered (CCU-SP). Temperature-compensated constant-voltage battery charger is powered by an S&C Voltage Sensor.
- External-Powered (CCU-XP). High-output temperature-compensated constant-voltage battery charger with unique battery management system is powered by user-supplied 120-Vac source.
