Programmable LED Controller  Programmable LED Controller



  1. 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.
  2. 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.
  3. 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.
  4. LED CONTROLLER:The light is automatically switched ON at dusk and OFF at dawn.
  5. 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)
  6. SYCHRONISATION FACILITY:The PLC-12 LED controller has provision for synchronising, multiple units to flash the lights in unison through GPS system.
  7. 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.
