The CFB is a desktop 200 VA ferroresonant CCR used to bench test airfield fixtures. It offers manual control for 5-step (2.8 A – 6.6 A) operation and can be used to test both incandescent and LED fixtures. Its integrated touchscreen provides additional functionality including manual control of output current settings and mode control to provide for automatic cycling through all CCR step settings. Includes a replaceable plug-to-receptacle cord set extension. A portable version of the CCR is available for field testing of airfield lighting fixtures. The portable power supply is mounted in a two-wheeled, rugged carrying case and can be powered directly using 120 VAC, 60 Hz or +12 VDC via a maintenance vehicle battery.
