Hi, I'm Jim Schuetz from NVE Corporation.
Today we're going to demonstrate the best-in-class high-voltage
performance for NVE's award-winning isolators.
Ordinary isolators are rated at 2.5 kV or 5 kV.
But NVE offers isolation ratings of 6 kVrms--or 8.5 kV peak.
These are called "V-Series" Isolators.
Our remarkable performance comes from
a unique polymer/ceramic composite barrier.
Other IsoLoop best-in-class high-voltage metrics include:
Barrier resistance; Barrier life. Comparative Tracking Index; and
So what we have here is:
a 10 kV hi-pot tester;
a socket for the isolator;
and a safety enclosure so nobody gets hurt.
Here are the isolators we're going to run:
NVE's 2.5 kV MSOP isolators-- the world's smallest isolators;
and wide-body parts with our best-in-class 6 kV isolation rating.
First we'll test the MSOP isolator.
These are rated at 2.5 kV-- remarkable for such a small part.
According to industry standards, isolators are 100% tested
at 120% of the isolation rating for one second.
So I've set the supply to 3 kV and 1 second.
I press the button...
And the part passes.
Now we'll crank up the voltage to demonstrate
our unique 6 kV isolator--an IL700V-Series.
So I've set the supply to 7.2 kV RMS, which is more than 10 kV peak.
I press the button...
And the part passes.
Let's take a closer look at how we test barrier life.
We connect the parts to 1500 volts DC,
We put them in an oven,
we bake them in an accelerated life test,
and then we wait...
We wait a long time…
A REALLY long time…
Here's a comparison of isolator life specs.
Optos, capacitive, inductive isolators.
Our spintronic isolators have a 44000-year life.
So we need to expand the scale.
The industrial age...
Great civilizations...
The pyramids...
Early settlers...
Farming…
Whoa! Are those woolly mammoths?
I guess we're talking serious
Mean Time Between Failure here.
Fortunately, with standard FITs extrapolations,
we haven't needed parts on life test
since the Pleistocene Epoch,
although we have been testing since the Clinton administration.
So to sum up, we've demonstrated
NVE V-Series Isolators
have best-in-class 6 kV isolation and 44000-year life.
