SCCR‑2A‑5K 频率调光恒流调光器为我公司自主研发、应用于机场助航灯光领域的低功耗恒流供电设备，与特殊设计的双光源 5W/5W LED 助航灯具配套使用。调光器恒定输出 2A 正弦波电流，输出频率分别为 51、52、53、54、55Hz 五个频率，对应配套灯具的 5 个光级。

与传统依靠电流大小调光的恒流调光器不同，本调光器通过改变输出电流频率实现灯具光级调节：灯具亮度不依赖电流大小，而是根据输出电流频率对应改变光级。在实际应用中，输出电流频率可在 48–55Hz 范围内可调，对应灯具的 5 个光级频率。恒定 2A 设计使灯具在不同亮度下均保持低电流运行，显著减小一次线缆功率损耗，适合对功耗和线路损耗敏感的应用场景。

The SCCR‑2A‑5K Frequency‑Dimming Constant‑Current Regulator, independently developed by our company, is a low‑power‑consumption power‑supply equipment for airport airfield lighting, used in pair with specially designed dual‑source 5W/5W LED airfield lighting fixtures. It outputs a constant 2A Sinewave current at five frequencies — 51, 52, 53, 54 and 55Hz — corresponding to the 5 light levels of the matched fixtures.

Unlike conventional CCRs that dim by varying current magnitude, light levels are adjusted by changing the output current frequency: fixture brightness depends on frequency rather than current. In practical application the output frequency is adjustable within 48–55Hz, matching the 5 light‑level frequencies of the fixtures. The constant‑2A design keeps fixtures running at low current under all brightness levels, greatly reducing primary‑cable power loss — ideal for applications sensitive to power consumption and line loss.

1. 调光原理：调光器恒定输出 2A 正弦波电流，通过改变输出电流频率（51/52/53/54/55Hz）向灯具传递光级指令，灯具按频率对应改变光级，亮度不依赖电流大小。
2. 低损耗优势：一次回路线路损耗 P=I²R。传统调光方式在高光级时电流增大，损耗随电流平方增长；本系统各光级电流恒定为 2A，线路损耗恒定且处于低位。
3. 功耗优化：灯具采用 5W+5W 双光源 LED 设计，配合 2A 低电流恒流运行，整套系统功耗低，适合对功耗和线路损耗敏感的应用场景。
4. 频率可调：实际应用中调光器输出频率可在 48–55Hz 范围内设置，灵活适配灯具的 5 个光级频率定义。

1. Dimming principle: The CCR outputs a constant 2A Sinewave current and transmits light‑level commands to fixtures by varying the output frequency (51/52/53/54/55Hz); fixtures change light level according to frequency, independent of current magnitude.
2. Low‑loss advantage: Primary‑cable loss P=I²R. Conventional dimming increases current — and squared loss — at higher levels; this system keeps current constant at 2A at all levels, so cable loss stays constant and low.
3. Power optimization: Fixtures adopt a dual 5W+5W LED source design with constant low‑current 2A operation, giving the whole system low power consumption — ideal for loss‑sensitive applications.
4. Adjustable frequency: In practice the CCR output frequency is settable within 48–55Hz, flexibly matching the 5 light‑level frequencies defined by the fixtures.

The HDK‑2X5W is a dual‑source LED airfield fixture of the HDK family, specially designed for frequency‑dimming applications and used as the dedicated matched load of the SCCR‑2A‑5K regulator. With a 5W + 5W light‑source configuration, its brightness does not depend on current magnitude: the regulator outputs five frequencies (51/52/53/54/55Hz) corresponding to the 5 light levels, adjustable within 48–55Hz in practical application.

Operating on the constant 2A loop with constant current at all levels, it keeps primary‑cable loss low; the dual sources provide mutual redundancy for high reliability in airport airfield lighting applications. See the HDK‑2X5W brochure for detailed specifications.
