Automated High Voltage Custom Electrical Test System

Being a custom automation integrator means that sometimes, when we need to generate and measure signals outside the range of typical instrumentation, we need to work with partners to produce specialized hardware.

In this instance our customer needed to charge a capacitor up to 1,000 Volts and then measure the voltage while discharging it into a device. The circuit also needed to discharge in both forward and reverse polarity which provided additional complexity.

The circuit board shown has a large capacitor, isolating and grounding high voltage relays, an H bridge, isolating amplifiers, and self-calibration features. Our design included ample indicator lights and test points for debugging and maintenance checks.

Being able to create these custom components gives us the ability to offer more flexible options to our customers and design intelligent solutions to solve their automation challenges.
