The PTC-CH Series Chassis Mount Temperature Controllers deliver the precision performance and long-term reliability you expect from a Wavelength Electronics temperature controller. PTC-CH Series controllers are found in such diverse applications as particle and droplet measurement, manufacturing machine vision systems, biomolecular interaction analysis, and more. They are CE certified. A PDF version of the Declaration of Conformance is available.PTC-CH controllers are available in different models so you can choose the one that best suits your application: PTC2.5K-CH delivers up to ±2.5 A output current PTC5K-CH for applications requiring up to ±5 A PTC10K-CH drives up to ±10 A PTC10K-SL can be tied to the 10 A driver to deliver a combined ±20 A output current The PTC-CH controllers operate from a single power supply between 4.5 V and 30 V.
