Airfield circuits are designed to supply a constant current series output. To power numerous
devices on a constant current series circuit, the constant current regulator (CCR) will produce a
high voltage across the output.
Input Voltage Warning
The input voltage for the 828HC is 120VAC. Ensure proper safety measures are taken before
servicing input power.
Input Current Warning
While the input current of the 828HC is low enough to run without issue on a 15A circuit, it may
be high enough to cause a hazard to personal safety. Ensure proper safety measures are taken
before servicing input power.
Output Voltage Warning
The nominal output voltage of the 828HC is 76VAC. Depending upon regulatory body, this may
qualify as a “low-voltage” output. Despite this, the CCR may provide output voltage in the
magnitude of 5x nominal output before open circuit protection circuits are activated. Ensure the
output lines of the 828HC are always populated. Always connect the male and female ends when
an isolation transformer is not plugged in.
Output Current Warning
The output current of the CCR is dangerous. It is designed to work in a 6.6 Amp series loop. The
CCR will shut down if there is an open circuit, but it will not turn off in a short circuit. Protective
devices are designed to protect equipment, not to protect personnel.
Prior to installation or servicing
Follow all local and national electrical codes for installation and service of the CCR.
Only qualified service personnel should be allowed to install and service the CCR.
Open all sources of electricity to the CCR. Follow lock out / tag out procedures to ensure
continued safety while completing work. Verify correctness of work done with a second set of
eyes before re-energizing the CCR.

Guarantee
Airport Lighting Company guarantees that the equipment manufactured by Airport Lighting
Company and covered by this manual has been manufactured to and will perform in accordance
with application specifications. Any defect in design, materials or workmanship which may occur
during proper and normal use during a period of one (1) year from date of installation or a
maximum of two (2) years from date of shipment will be corrected by repair or replacement by
Airport Lighting Company, with transportation costs borne by the purchaser. This guarantee
covers the 828HC Ferroresonant Constant Current Regulator.
