PTC-20 2-channel temperature controller (heating and cooling)
The PTC-20 controller from npi electronic GmbH is designed for heating and cooling electrophysiology preparations. It has two independent channels, each with an integrated thermometer, a digital display and a protected bipolar output for controlling Peltier elements or resistive loads. The system ensures low-noise operation, maximum safety thanks to electronic protections, and precise control via a PI controller with adjustable parameters. The interface allows direct adjustment of output temperature or voltage, and analogue outputs for external recording. The PTC-20 is mounted in a standard 19″ cabinet with integrated power supply.
