WM-L780A Long-Range LED Beacon

The WM-L780A LED beacon is primarily designed to replace long range requirement for various lightbeacon and lighthouse applications using rotating beacons, providing an effective range of up to 21 nautical miles (or in excess of 150,000 cds). Flash lengths are user selectable rather than achieving through rotational speed which has very short flash lengths.

The configuration are depending on the current setting and type of LEDs used, and is completely flexible to suit end-user’s unique requirement of luminous range.

The heavy duty and powerful WM-L780A long range LED beacon housing is made of corrosion-resistant, cast aluminium alloy material that holds an array of toughened, WM-patent designed, UV-stabilized acrylic fresnel lens ensure minimum variation in output intensities.

The WM-L780A never needs to be opened for servicing and maintenance because the light is factory sealed to IP66 and with no moving parts and lamps to replace, the WM-L780A long range beacon offers a long and reliable service life.

The heart of the WM-L780A is the intelligent digital controller module accepts a wide range of input voltages. It regulates and maintained constant distribution of current to each tier and sub-groupings of LED array. Precision controlled to ensure the LEDs are operated and produces constant intensity with highest efficiency.

Flash characters are programmable via an InfraRed programmer unit (SYD-1 MASTER). Up to 256 preprogrammed flash codes are available and other commands available are FORCING ON / OFF, RESTORE to PHOTOCELL operation and BEACON ADDRESS (for telemetry purposes).

Synchronisation of the WM-L780A long range LED beacon is either by hard-wired or wireless (GPS). For the optional wireless synchronising feature, GPS receiver module are incorporated inside the WM-L780A LED beacon.

Telemetry tap-off / Communication with the WM-L780A long range LED beacon is done via RS485/RS232 serial communication leads (provided upon request).
