Hi guys and girls, I need your help!
I have several standard 5v relays, you know the type standard blue Square blocks.
They are rated 30v DC or 250V AC
I need to use them for 40-60v contactor, about 0.10- 0.15A current draw.
(11w during making contact, 7w continue)
The Contactor does higher capacity, max 350A..
Voltage difference is between 40 and 60v (officially 48v units)
At both top or low it needs to disconnect / release.
Usual voltage is 50-55v
(16*3.2v nominal LiFePO4)
During testing phase I will switch the relays several times.
After this, perhaps a few times per year automatic release due too high or too low.
Can this be used????
Max 30v (2A) probably for Arc problems at higher voltage with 2A..
My capacity is really low....
And ..
If it does fail, how will it fail?
Keep the contact?
That would be catastrophic..
Or release and no longer work to reconnect??
(Last one not a problem, easy enough to replace)
Or do I need different relay?
PCB design is for this standard 5v units. (See picture, first one I found)
Not sure if there are 5v units that can switch 60v with the same footprint
.thank you for your input!!
