CML Arc Sensors are equipped with a small, below-cutoff aperture for the viewing of regions where an arc may occur. An optional reverse power input is available. This input allows triggering on reflected power from the output of a diode detector installed on a reverse power monitoring directional coupler.

The circuit assembly used on CML Arc Sensors can be supplied for mounting on a viewport for vacuum waveguide applications. They can also be supplied on a mounting plate for field replacement. 

CML's circuit assembly has the following specifications:

• Optical Detector:

  • Phototransistor.

• Power Supply Voltage:    

  • 13 to 31 VDC.

• Input Current:        

  • 80 mA DC (with test light actuated).

• Output Signal:         

  • Armed: 16 V minimum.

  • Fired: 2 V maximum.
