An led driver or power supply is a type of power conversion circuit that delivers constant current as opposed to constant voltage. Constant current led drivers are designed for a designated range of output voltages and a fixed output current ma.

Ot 1dim nfc ip67 outdoor. Constant current dimmable. Ot 4dim ip20 outdoor. An led driver is an electronic circuit that generates a constant output current from the supply voltage.

There is no standard outputs when it comes to constant current dimmable led drivers. 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. In electrical engineering this circuit is often referred to as a constant current source. Led light engines and modules.
