An LED driver is an electrical device that regulates power to an LED or a string of LEDs. It is a crucial piece to an LED circuit and to operate without one will result in system failure. Using one is very important in preventing damage to your LEDs as the forward voltage (V f) of a high-power LED. Constant current LED drivers are designed for a designated range of output voltages and a fixed output current (mA). LEDs that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps (mA) or amps (A).

The OPTOTRONIC programmable dimmable family consists of highly efficient, constant current 25W, 40W and 55W LED power supplies. They are programmable between the range of 150 to 1250 mA for the 25W, 400 to 1400mA for the 40W, and 700 to 2000mA for the 55W with a 1mA resolution. The OPTOTRONIC programmer does not require the power supply to be powered or connected to AC line voltage while programming. The power supplies are available in dimming to 1% with built in 0–10V dimming enabling direct integration and operation with standard dimmers, sensors, as well as energy and light management systems. In case of LED module thermal overload, the family’s integrated LED thermal protection function allows the power supply to reduce the output current. This function is fully customizable by the customer. The family comes in a standard industry housing with dual entry connectors to simplify installation.
Dedicated auxiliary DC output helps integration of fixture integrated sensors like the OSRAM Connected Lighting Module (CLM) DIM thus eliminating need of secondary DC supply.
