Oceanic Systems has launched a dedicated NMEA2000 navigation light controller designed to control and monitor 8, 16 or 24 LED navigation lights. The main 5971 controller unit controls eight lamps, and with the addition of one or two eight channel 5972 expansion units, the additional lamps can be controlled.
The product is designed to control the switching of LED navigation lamps and to monitor each lamp’s power draw, ensuring any lamp or wiring failures are monitored and an alarm is raised if necessary. Additionally, the unit measures the power on hours of each navigation lamp and warns when they have exceeded 50,000 hours so that they can be replaced and stay within the IMO regulations.
The 5971/5972 complies with the recommended DNV Classification rules with built-in manual overrides for each channel and a local mimic panel which indicates the state of each lighting channel and shows any error conditions occurring.
It uses 12 or 24 volt primary and standby power feeds for the LED navigation lights and shows a power good indicator for both supplies. This automatically falls back to the standby supply if the primary display fails.
