00:00:02.820 --> 00:00:05.440
NVE's groundbreaking V-Series isolators

00:00:05.440 --> 00:00:10.160
were recently upgraded to a best-in-class 
seven kilovolts isolation spec.

00:00:10.160 --> 00:00:12.967
We demonstrated seven kilovolt testing 
in a previous video.

00:00:13.896 --> 00:00:15.442
But there's an even tougher test.

00:00:16.000 --> 00:00:17.440
Each part is required to be

00:00:17.440 --> 00:00:21.320
tested with a 20% safety margin 
for one second.

00:00:21.320 --> 00:00:26.261
That's 8.4 kilovolts RMS,
or 11.9 kilovolts peak.

00:00:27.304 --> 00:00:31.360
Non-optical isolators 
have never been able to meet that standard...

00:00:31.360 --> 00:00:32.552
...until now.

00:00:33.272 --> 00:00:36.161
We can demonstrate with our new, improved evaluation boards.

00:00:37.564 --> 00:00:39.568
An Arduino is generating "heartbeat" data

00:00:39.568 --> 00:00:42.323
on the inputs to 
a pair of four-channel isolators.

00:00:43.827 --> 00:00:46.640
An oscilloscope fed by 
a digital-to-analog converter

00:00:46.640 --> 00:00:48.248
shows the isolated outputs.

00:00:51.087 --> 00:00:54.325
When we power the output side 
of the isolators, the waveform appears.

00:00:54.658 --> 00:00:56.776
The heartbeat shows 
the isolators are working.

00:00:57.723 --> 00:01:00.609
The highpot tester is set for 
8.4 kilovolts AC.

00:01:03.766 --> 00:01:05.920
The parts pass easily, 
and they're still working.

00:01:05.920 --> 00:01:10.023
as the heartbeat shows.

00:01:10.023 --> 00:01:12.023
Here's the schematic for the setup:

00:01:12.554 --> 00:01:17.160
The Arduino provides eight-bit ECG data.
An R/2R resistor array

00:01:17.160 --> 00:01:20.480
on the isolator outputs 
feeds the isolated signal

00:01:20.480 --> 00:01:24.034
to the oscilloscope.

00:01:25.420 --> 00:01:28.190
This is a summary 
 of the parts we used in this demo:

00:01:28.734 --> 00:01:30.112
There are links in the YouTube description.

00:01:32.497 --> 00:01:35.040
V-Series isolator features include:

00:01:35.226 --> 00:01:38.480
best-in-class seven kilovolt 
isolation voltage,

00:01:38.480 --> 00:01:44.051
Each PART is tested at 8.4 kV for a second,
like we did in this demo,

00:01:44.314 --> 00:01:48.019
and each LOT is tested at 7 kV for a minute.

00:01:49.405 --> 00:01:51.089
They have best-in-class barrier resistance,

00:01:51.660 --> 00:01:54.024
and best-in-class working voltage.
