Ferroresonant Constant Current Regulator | FAA L-828 & L-829

Made in the USA flag

Compliance and Applications

Certified to FAA AC 150/5345-10 (Current Edition)
Our L-828 / L-829 Constant Current Regulator is used to provide power to airfield lighting systems. It offers a selectable AC constant current to change the airfield lighting intensity as needed based on weather conditions.

Features

• Ferroresonant design allows for high-efficiency, high-power factor sinusoidal constant current output
• Efficiency over 90%, power factor .99
• Stable output current is not affected by flashing loads from strobes or runway guard lights
• Intuitive, fully digital interface included on all models
• Powerful software allows CCR to be recalibrated in field, recall previous settings and calibration, change brightness steps, track warnings and faults, and more
• Digital output current reading and digital output voltage reading on all models
• High quality lightning arrestors used for output connections
• Transient protection on input power circuit ensures long CCR life and equipment protection
• Open circuit, overcurrent, and overvoltage protection on all models
• Safety interlock disconnects output power when cabinet door is opened
• Quiet operation
• Stackable
• Enclosure size:
– 1kW-10kW: 24″W x 25.25″D x 40″H
– 15kW-30kW: 36″W x 30.25″D x 40″H

Additional Option Information

• Internal S-1 Cutout: An S-1 Cutout is installed directly in the enclosure of the CCR. Once the CCR is turned off, the S-1 Cutout handle may be removed and taken with servicing personnel to ensure safe work conditions.
• IRMS: The IRMS (Insulation Resistance Monitoring System) can be configured to run manually or daily. With this option, the CCR will provide a digital resistance measurement to the user on the front display. The resistance reading can be tracked by site staff to gain insight to field-circuit integrity and to anticipate required maintenance.
• Integrated Circuit Breaker: A circuit breaker is included inside the CCR that is actuated with a door-mounted handle. The door-mounted handle is capable of accepting a lock for lock-out-tag-out safety measures.
