Product Overview:

Precision 50 Watt TEC Controller Overview

These 50 watt low noise linear TEC controllers for semiconductor diode lasers are offered in a small form factor module. They are designed to provide stable temperature control of the peltier cooled stages. This controller is a good solution for low cost laboratory controller applications or as a module for product integration. The control loop is a fast hybrid PI circuit. This module accepts feedback from thermistors, RTDs, AD590s and LM335 sensors. Status LED's quickly show temperature control on/off. These modules also have mounting brackets for easy attachment to a chassis or an optical table.
