BEWARE of TEK MADE RELAYS
Well, these days I use JD1914 12V SPDT heavy duty relays in one of my products. Beware of a lot of fakes out there. The fakes lack a copper braid conductor augmentation and this results in a resistanc

OT capacitor question
Thanks, since the application is inside a secure switch gear panel with safety lockouts, and qualified electrical personnel can only access in full safety gear, shock hazard isn't such a concern. thx

That would be great. I did that back in 2013 I think. Mostly Newark.com parts. 2465A and 2465 still going strong. Ancel

Seen on the net today
I have a different take on the right to repair: Here in Trinidad, I've developed an economically viable and non invasive means to Rejuvenate Used Lead Acid Batteries for tropical use. Cost me 4 years

I have one of these, but because of the 'defective' built in controller I never used it. Most of my boards are doublesided anyway
