constant current led driver 700ma
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 or amps. These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the LED system.
SMARTS specialize in 3 kinds of dimmable constant current led drivers, they are triac dimmable driver, 0-10v dimmable driver, and DALI dimmable driver, and supply vary of output current with 300ma, 350ma, 700ma, 900ma, 1200ma 1400ma and so on..
Taking our triac dimmable constant current led driver 700ma as example.

Drawing of constant current driver 700ma:
How to choose a correct constant current led driver for your LEDs?
1). Firstly, pls confirm what's the spec of your LEDs? like output voltage and current.
2). Secondly, how do you plan to connect them? in parrel or series?
3). Thirdly, pls confirm if you need dimmable driver or non dimmable drivers?
In a words, for constant current LED driver, the output current is constant, and the LED voltage range must be within this range for driver to operate.
Anyway, if you have any requirements or questions on your LEDs applications, pls contact us!
