The CXD7 type Morse signal light is a robust and reliable navigation aid designed for maritime communication. It operates on a rated voltage of either AC110V or AC220V, with a power output of 2*25W, utilizing an incandescent lamp as its illuminant. The white color of the light ensures high visibility, which is further enhanced by its 360° horizontal arc, making it visible up to 5 nautical miles. The lamp holder model is B22d, and the unit is designed to withstand harsh marine conditions with a protection class of IP56, indicating a strong resistance to water ingress. The cable's outside diameter compatibility ranges from Φ12 to Φ14, and the seat-mounted type installation method allows for straightforward setup. The CXD7 is built to operate in a wide range of ambient temperatures, from -30℃ to +55℃, ensuring functionality in diverse climates. Its construction involves a high-quality aluminium alloy for the lamp body and engineering plastic for the lampshade, resulting in a durable yet lightweight device at 4.9kg. This combination of features makes the CXD7 an essential tool for ships requiring reliable Morse signal communication capabilities.
