Looking for DC wire to wire power connectors, overwhelmed | 350v+ 2A+

[picklesrus]

Hello,

Checking out Mouser, Digikey and general Google, I am simply overwhelmed by the number of DC Connectors available. I am also finding it difficult to filter through the tremendous amount of products to find something that will work for what I need.

Currently the circuit is of LEDs, around 256v running 1.4A.
I think it's a good idea to get something rated a little higher so I can use them for bigger projects, say capable of 350v running 1-3A

Waterproof would be a plus.

Is there an easier way to go about finding DC connectors, or can have some suggestions for some that are currently available for sale online from a site like Digikey or Mouser?

tell us more about these LEDs that need 256VDC please

7 x 36v Integrated COB LED in series, being run at 25% max current.

Correction to my OP, the amperage would never actually be more than 2A, more than likely would be either 1.7A, 1.4A or 0.7A

is there a good reason why you cant run them in parallel and keep the voltage to a safe 36VDV ?

I'm new to this, but what I understand is that if one of the LEDs in a parallel configuration fails, the current it was using would be redistributed to the other LEDs in the circuit increasing each LEDs load, which could lead to a thermal runaway scenario.

If they run in series, a failed LED would only mean that the driver would deliver less current, and each LED would receive the same current as it was which wouldn't be a problem.

I was hoping there would be a connector kit available, like a box of molex male and female connectors, but that would be able to handle up around 250-300v.

As Davenn said, more detail on what you are using, any circuit drawing you can muster up and possibly links would be helpful.
Thermal run away is a transistor characteristic under certain circumstances.

Playing with high voltage is asking for trouble.

Probably a good idea to read this resource too..

I will try Bluejets.

Thank you Martin this is excellent.
