FEATURES: , The PLC-12 Programmable LED controller is a
microcontroller based unit, incorporating all the control/ indication functions
required to operate LED lanterns. The PLC-12 PCB is contained in our standard 110 mm
dia. enclosure for maximum environmental protection.
CURRENT REGULATION: High efficiency Pulse-Width Modulation for variable input
voltage has been employed to stabilize the LED current which is set in the factory
as per LED load requirement.
CHARACTER PROGRAMMING:256 characters as per IALA have been programmed in the
PLC-12 programmable LED controller. Two small
selector switches each 16-way giving 16 x 16 = 256 character are programmed. Any of
the characters can be selected at site with the selector switches provided.
LED CONTROLLER:The light is automatically switched ON at dusk and OFF at
SOLAR CHARGE CONTROLLER:The PLC-12 LED controller incorporates a temperature
compensated solar charge regulator to optimize the charging of the battery and
prevent its overcharging and disables load at low voltage.
Solar voltage upper limit setting for charging Battery:-
For 12V system : 13.5V to 14.5V in 0.1V increment. (Solar panel input
disables above 14.5V)
Load disabled setting from Battery.
For 12V system : 10.5V to 11.5V in 0.1V increment. (reconnects at 12V)
SYCHRONISATION FACILITY:The PLC-12 LED controller has provision for
synchronising, multiple units to flash the lights in unison through GPS system.
MONITORING FACILITY:The PLC-12 LED controller has provision for working with
our marine Remote Monitoring unit. MRM-100 to monitor all the functions of the Buoy
and navigational light and sending the information to one or many designated mobile
Phones with GPS and GSM network.
12V to 24V d.c. Supply
