Low Noise Power Supplies

Chart comparing the spectral noise density of an analog solution to a QorTek digital solution. QorTek's digital solution is shown to be significantly lower.
Low noise digital power supply. It's square-shaped, green, yellow, and black.
A CAD model of low noise power supply. There are three components being shown that are green, yellow, black, and blue. The QorTek logo is branded on each of them.

DC-DC converters designed for low noise and fast transient performance, all while keeping tight regulation specs. Our low noise power supplies come in a variety of different industry standard sizes and use COTS when possible while still meeting typical MOTS electrical and mechanical performance requirements. They are all digitally controlled which enable programmable output voltages and allows the potential for field upgrades with updated firmware.
