------Question for PE3W02799/HS-12 Please Put your question below------
Hoping to check the maximum voltage rating for this cable?
Thanks,
Eli
Hello eli.swanson,
Welcome to the DigiKey TechForum.
I contacted the manufacturer. They stated the voltage rating, of that cable, is 500VAC.
It may be of use to clarify precisely what sort of “rating” is sought.
Working voltage ratings for constituent components of the sort used typically run 1.4kV+, but the touch-likely nature of standard banana jacks may reduce “allowable” potentials to something well less than 100v if safety is a concern.
The figure received from the supplier likely reflects a potential to which the assembled product is tested and/or warranted.
I’m looking for a cable that can withstand 700V DC, I’ll talk to my supervisor about whether or not there’s a way to reduce the risk of contact in our lab.
When you say “components of the sort,” are there cables similar to this one that can withstand higher voltages?
Best,
Eli
The datasheet indicates that the P/N of interest is built from a length of RG223 between a double banana plug and an SHV jack. Looking at the withstand ratings for type examples of each individually, the cable looks like the weak spot with some examples giving figures of 1.4kV.
Because assembly processes aren’t perfect and because it’s unwise to offer “ratings” that one hasn’t verified, the supplier of the assembly is likely offering a “rating” that reflects conditions of their outgoing test. I’d wager a cold one that most examples off the shelf would tolerate 700VDC just fine, but one assumes responsibility for any Things That Go Wrong that stem from doing so.
Controlled-access lab environments are held to less stringent standards than public environments, because it’s assumed that those given access are informed about potential perils and capable of navigating them. Dual bananas might be a very reasonable connector option for the circumstance given proper protocols, but seems a bit causal for impromptu bench monkey work.
As far as getting a cable that is specifically rated for 700vdc or more, I would recommend reaching out to Pasternack to see if they would either make one or if they can have the PE3W02799/HS-12 put through testing that would give it a 700vdc+ rating.
