Dimming Led Driver Constant Current

Basically you will need a driver per led.

Dimming led driver constant current.

What is a constant voltage led driver. Use our lighting designer tool to find your desired system match of led module driver. Constant current is essential to best performance. Constant current dimmable.

0 10v dimming this dimming type is used in most new construction and commercial applications. Astrodim for autonomous dimming with five independent levels astro time. Advantageously in order to adapt the constant current led driver circuit arrangement for dimming the sensed current output signal provided to the secondary controller can simply be modified to. The 17 to 29 volt range just means that it will successfully drive 1400 ma through an led string when the voltage needed to produce that current varies between 17 and 29 volts.

The power supply has a synchronisation function which allows up to 10 drivers to be connected. Constant current compact indoor. Use our driver selector tool to find your desired led driver. A constant current driver is the best way to drive high power leds as it maintains a consistent brightness across all leds in series.

Including a voltage range of 2 90vdc and current range of 500ma. Constant voltage drivers are designed for a single direct current dc output voltage. It also features a programmable input undervoltage shutdown. This voltage difference could be produced by differing numbers of leds in a string or using the same number of leds but of different colors.

So the critical spec on your led driver is the 1350 ma figure. Phase dimming is only available in 120v input. The linear dimming input ld can accept a reference voltage of up to 2 5v. The ic features fast pwm dimming response.

Cv60 constant current led driver cv60 is a 60 3w two in one dimming function constant current led driver with an input capability of 180 to 295vac. The ic is equipped with a current limit comparator for hiccup mode output short circuit protection. Hatch led drivers with a z in the part number after the current rating are compatible with 0 10v dimmers i e. Most common constant voltage drivers or power supplies are 12vdc or 24vdc.

Constant current outdoor. Constant current has a big downside though driving an led with constant current scales very bad to multiple leds. The dimmer is wired in line with the output of the driver. Hotter higher current at same voltage causing a thermal runaway situation.
