Default is it safe to run my diode .....

hi guys,

is it safe to run my diode off of my adjsutable power suppy with no driver ?

looking at the reading from the driver its putting out 1.25A @ 8. something V


so running my diode direct from the power pack at 5v and 1A is ok? right?





jack

We have no clue as to what PS you are referring to...
Is it a Power Supply or a battery pack...
We have no idea as to which "Diode" you are referring to..

A main power supply ???
Like the one I use to power my shop...???

A picture is worth 1000 words and a Link to
the product is worth even more...

I's like me asking you if I can use this Distributor
on my car.....

I have ran my diode off of a simuliar lab psu to the one you linked,
that works fine, as long as it has current limititing, like the one you posted.

But what exactly do you mean by "run it directly off the power pack"

Default Re: is it safe to run my diode .....

im just wondering if its safe for the diode ... running it using the psu with no driver just connected strait to the psu. i was think that maybe the drivers ran at a certain hurtz or maybe the slight fluctuation in current from the psu could damage the diode

Default Re: is it safe to run my diode .....

Should be DC, hertz wouldn't be a factor...as said earlier if you set your voltage around 5v and the PSU regulates the current and you can set it as well then it shouldn't be a problem..most PSUs have built in bleeder resistors for the large capacitance they carry (unless is a switch mode PSU) but it's wise to short the leads together coming from the PSU (with the power off of course) before you connect the diode..any left over charge could blow your diode..I learned this the hard way with PSU and a high end DAC chipset I was working on....just set your current to less than 1.8a and you should be good to go. This is also assuming the diode is well heatsinked.
