I added a mod for this driver as suggested by supplier so that current can be adjusted to a desired value. there is a jumper from one terminal of the trimpot to one resistor. Just see the backside.

Pls be informed that in this constant current driver, reducing the current would mean that reducing the voltage also.

But since it easier to test for voltage, I would recommend initially during init1al run, with led connected,
1. for 128w led- set the voltage to 26v
2. For 98w led- set the voltage to 23v

But if want to test the current immediately and know how to test it properly, pls go ahead.


In the picture below, LOWER LEFT SIDE, there is a small blue trimpot to adjust current/voltage

clockwise- increase
counterclockwise- decrease


.
ONE VERY IMPORTANT INFORMATION ABOUT CONSTANT CURRENT DRIVER.

If there is no load or led is not connected, the voltage of 30v will not go down or up no matter
what adjustment you made in the trimpot.


For example, you adjust the trimpot counterclockwise, the voltage reading will still be 30v.

But when you connect the led,thats the time you will notice a reduction on voltage.



So when I shipped the driver, I turned the trimpot counterclockwise at lower voltage.

So adjust the trimpot accordingly when led is connected


Also pls be aware that there is a micro processor at the backside of the driver. Pls put a spacer when mounting in the box.

There is no hole for mounting the driver. So you need to bore a hole in a clear area of the circuit board.

In my driver i already decreased the volt to minimum and I am getting 29v without
connecting the led so if I connect the led then can I lower the voltage to 25v?

if you adjusted the trimpot counterclockwise prior to connecting the led, the voltage will be low already when you connect the led

I shipped them at low voltage. So if you connect the led, the led may not lit up.
So adjust the trimpot counterclockwise to get the desired current/voltage.

I apologize to those who bought this.

I forgot to post a very important information about this driver.

This driver is not available in any on line store .

I just worked out an arrangement for the manufacturer to mod the driver which is intended as
waterpoof constant current driver.

I still paid for this driver , the same the price of waterproof driver but mod has been done to make it compatible for the led driver I sell here.

One reason I like this driver is because it can be use for 72.98,128 up to 180w led.

I have been using this since July 2013 last year and so far, no issue at all. it is installed in my home theater projector.
