Spirit Series™ Thyristor CCR
L-828 / L-829 Constant Current Regulator
The Spirit Series™ Thyristor Constant Current Regulator (CCR) was designed to provide an economical solution for powering airfield lighting series circuits at General Aviation and commercial airports. With powerful control and monitoring capabilities, it is also ideally suited for airports operating in CAT II or III conditions. The Spirit Series™ CCR uses the same proven hardware and firmware used in our Freedom Series™ CCR and is a result of forty years experience in airfield lighting power and control solutions.

System Application
Thyristor (also known as SCR) type regulators are the most common type of CCR installed around the world, largely due to the low cost, high reliability and years of field proven experience. Applications include:
- General aviation, commercial, and military airports operating in VFR to CAT IIIb visibility conditions.
- Runway and taxiway edge lighting, centerline lighting, signs, approach systems, PAPI, VASIS, LAHSO, Runway Guard Lights.
- Surface Movement and GuidanceControl Systems
(SMGCS) using powerline carrier technology to
control and monitor individual lamps or segments.
Note: Thyristor CCRs can be used on any airfield circuit, however ferro-resonant CCRs are recommended for circuits with oscillating loads.
Standards Compliance
- FAA Advisory Circular 150/5345-10F, June 24/05, Type L-828 and L-829.
- Transport Canada CCR Specification K290-2.
- Canadian Department of National Defence Standards.
- ICAO Aerodrome Design Manual Doc 9157, Part 5.
Technology Benefits
- Digital control for precise waveform accuracy, high-speed response, and local data storage using Digital Signal Processor technology.
- Digital output accuracy and drift-free circuitry for increased lamp life.
- Digital operator interface provides full monitoring, diagnostics, and alarm indication. Dedicated status LEDs provide clear indication of warning and fault conditions.
- Membrane keys with tactile response provide maintenance personnel with access to all display values and configuration parameters.
- All ratings are dry-type and convection air-cooled. No cooling fans are required.
- Unique wall mount option allows 1 - 7.5KW regulators to be installed at eye level for ease of maintenance - a welcome option for senior maintenance staff.
- All ratings can be stacked to save floor space. Regulators up to 7.5KW can be stacked 3 units high. Larger regulators can be stacked 2 high. Castors are available for 10 - 30KW regulators.
- The CCR is equipped with over-current, open circuit, over-voltage, input and output lightning protection. A safety interlock ensures power is disconnected when the door is opened.
- All CCRs are user configurable, including selection of 1 to 5 brightness steps, output current adjustment, selection of monitoring features, operational parameters and alarm setpoints.
- User-configurable failsafe capabilities allow last state (latching) or preset brightness selection upon failure of control system.
Monitoring Capabilities
- Industry leading monitoring and diagnostics including analog output current, commanded and actual brightness step, elapsed time at each step, number of operations, warning and fault conditions including door interlock, local switch position, over current, over voltage or open circuit trips, communications or hardware failure.
- Available input and output power monitoring (current, voltage, VA, power, and power factor)
- Available L-829 monitoring functions including primary power, circuit trips, loss of VA, brightness within specifications, number of failed lamps per circuit with warning and alarm indication.
- Available insulation resistance monitoring (Automatic Megger) with alarm indications.
- Available fully redundant communication support using 100MB Ethernet (Ethernet/IP or Modbus TCP) or RS485 (Modbus or Allen-Bradley DF1).
- Redundant 24VDC backup power provides monitoring from the control system even during power failure to the CCR (included with communication options).
- Direct communication interface to Liberty Freedom Series™ or Spirit SE Series™ Airfield Lighting Control and Monitoring Systems.
