Airfield Lighting Systems TSR regulating transformer. Unique to ALS.
A regulating AGLST, or TSR, is an electronically controlled AGLST, designed to provide a different lighting profile to the other luminaries on the same circuit.
All TSRs, are available in the following power ratings: 45W, 65W, 100W, 150W and 200W with input currents of 6.0A, 6.6A and 12A.
The cost is higher than that for standard transformers but is negligible in comparison with the cost of providing a dedicated circuit and CCR.
