ROTATING BEACONS MBR300L State-of-the-art LED Technology The MBR300L is a medium and long-range rotating beacon, fitted with state-of-the-art LED instead of marine lamps. This provides a low-consumption and low-maintenance beacon for more than 100,000 hours. It is ideally designed for isolated solar installations, able to reach up to 21 nautical miles. Minimum maintenance Its compact design includes a step-by-step rotating motor and an electronic control unit inside the lantern, thus completing a watertight beacon easy to install and with minimum maintenance. Long service life High-quality and resistant manufacturing materials, such as glass and marine aluminium, provide a long-service life under the harshest marine conditions. This beacon strictly meets IALA Recommendations. • State-of-the-art LED technology. • Maximum-efficiency luminous system. Up to 21 nm (T=0.74), 32 nm (T=0.85). • Up to 10 W power consumption. • Average operation lifetime over 15 years. • No lampchanger needed. • Compact design. • Maintenance-free, brushless direct-drive motor. • Rotating speed programmable from 0.5 to 10 rpm. • Status and alarms available for remote monitoring, by opto-isolated signals and RS-232 serial port. • Short-circuit, reverse-polarity and transient over-voltage protections. • Easy installation. •
