Notes
|
1. All parameters NOT specially mentioned are measured at 110V/230VAC input , rated load and
25℃of ambient temperature.
2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with a
0.1uf &47uf parallel capacitor.
3. Tolerance:includes set us tolerance,line regulation and load regulation .

What is the constant current led driver?
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). These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the LED system.
