LD48 DC Lamp Controller

LD48 Image

   The LD48 lamp controller from Technovision provides the capability of controlling up to 48 individual DC lamps or LEDs. This can be achieved as a "stand-alone" controller or by having the LD48 controlled by another device such as a computer or KPC-2 controller. There are two RS-232 ports on the LD48 as well as a two wire TTL (5 volt) serial interface (DATA and CLK) on the external control connector. By combining 5 lamp driver boards, a total of 240 individual DC lamps or LED's can be controlled through one KPC-2 controller.
