The L-828 CCRs are designed to
• supply three or five precision output current levels (6.6 A/20 A
maximum) to power airport series lighting circuits on runways and
taxiways.
• accurately regulate the output current to within ±1% of the adjustable
nominal levels from no load to full load and with input voltage
variations of -5% to +10% of nominal.
• maintain the nominal output current levels even when 30 percent of
the isolation transformers in the series lighting circuit supplied by the
regulator have open secondaries
See Figure 2-2. This subsection describes the L-829 CCR. The L-829
uses a URC to provide regulator and control functions. It also uses the
Advanced Control Equipment (ACE or ACE2) for control and
monitoring functions.
NOTE: Figure 2-2 shows a ferroresonant L-829 (15 kW/6.6 A) CCR.
The other L-829 CCRs (4, 7.5, 10, 20-30 kW/6.6 A/20 A & 50/70kW) may
differ in size and appearance.
