Measuring only 1" x 1" x 1.5", the CT325 temperature controller can manipulate up to 240W of heat. The unit derives its power for operating both its electronics and the heating element from a single dc supply. The miniature unit accepts input from either a 100½ or 1 k½ platinum RTD or a 50-k½ thermistor. Test points are provided that allow users to monitor setpoint and temperatures with a voltmeter, with output temperatures indicated in mV/¡C. Completely sealed in epoxy, the controller is suitable for use in outdoor systems, telecomm enclosures, medical equipment, and automotive components.
