Where can I get an equivalent to this led power supply?

Just trying to find a driver that has the same specs as this.


Thanks

Can't make it out.. Best guess is 70-1xxV out
420mA constant current
But lists it at what looks like 70W
Combined it doesn't make a lot of sense.
Secondly looks dimmable but doesn't list dim type (10V, 10VPWM ect)

So need a better pic but probably hard to find an exact match.
Inventronics used to make ones close to those specs but hard to find.

Thanks for your input


Sorry about that

Here is a better photo

Yea I can't find any Meanwell drivers that have similar stats either.


Thanks!!

Quick search - nothing -- but this place offers a chat over the computer.

Yea.. typical "black box" driver.
AFAICT nobodyt's sourced any of these anywhere.. SBReef does carry them for their lights ( assume same or similar driver) but that doesn't do you any good..

As long as a driver is close you are ok.
Sad thing is you will either go up or down in current..both have their plusses and minuses..

For reduced current.. this should work fine though the 5V high end difference "may" be annoying (depends on actual string voltage at 350mA) but diodes will light..:

If you currently dim the fixture you should be fine..
IDLC-45A-350

More mA's lower top end
IDLC-45A-500

Now here is the catch:
BB's run 28 or 26 diodes in a string..
86/28= 3.07V each
86/26 = 3.3V each..

Sooo w/out real data there are a lot of guesses here..
Technically those drivers should work fine to light it BUT what current they will draw on each string is ???

May hit setpoint (350 or 500) may not..
There are simple work-arounds like either
removing a diode and adding a jumper wire
just a jumper wire
adding a red or 2 (lower V(f) )
or living w/ less than max current.

I'll peek to see if I can come up w/ a more elegant solution.
Ideally..

How funny.

This is literally the only site on the internet that sells this exact driver.

I came across this website as well.

Also you must be a psychic because....I have the SBReef led. My pal gave it to me and its just got 1 bad driver for the white channel.

I've emailed SB Reef but have not gotten a reply from them.

You are awesome sir.

I might as well just order it from here.

Thanks for your thoughts and input.
