navigation lightwith alarm

Navigation lights control panel for the TEF 2898/TEF 2870 Lanterns. Main supply 24V AC/DC Technical Data Material - Anodised aluminium with engraved text, specified by customer Supply voltage - 2 x 24V AC/DC Max. Power consumption - 340 W (8 circuits) - 500 W (12 circuits) - 660 W (16 circuits) Load - Filament lamps / 24V 25-40W Dimensions (8 circuits) - 144 x 240 x 150 mm Dimensions (12 and 16 circuits) - 144 x 384 x 150 mm Cut out dimensions (8 circuits) - 124 x 220 mm Cut out dimensions (12 and 16 circuits) - 124 x 364 mm Weight (8 circuits) - 3,5 kg Weight (12 circuits) - 5,0 kg Weight (16 circuits) - 5,5 kg Features For console mounting Easy installation (all terminals are separated from control box with a 1 meter flexible conduit) Prepared for connection of two 24 V AC/DC power supplies Automatic selection of power supply, with preference on main supply Alarm when a supply is missing The lanterns are switched by two pole, rocker switches on the front panel. Dimmable LED’s indicate when a lantern is on Visible and audible alarm when a fault occurs in a circuit (broken bulb, short circuit etc.) Voltage drop in long cable length can be a problem. This is compensated by connecting specific circuits to a higher voltage than 24V. Transformers delivered by Tranberg AS have output for six different voltages Tranberg AS can assist calculating voltage loss in cable to lantern. Equipped with an ”alarm-relay” with potential free contact set for remote monitoring Test button for testing of LED’s and acoustic alarm.
