325 In Stock

The 325 by Newport is a Laser Diode Temperature Controller of notable capability, designed to cater to various user requirements with its three distinct operating modes: constant ITE (TE cooler), constant T (IC sensors), and constant R (thermistor) modes all while delivering 50 W of high output power. This controller boasts a rapid hybrid P-I control circuitry that ensures not only efficiency but also a low-noise and secure output current. This controller features an ITE current limit setting, which serves as a protective measure for TE coolers, irrespective of the selected operating mode. The 325 controller can provide direct temperature readings in degrees Celsius (°C) when utilized with IC sensors, encompassing a broad TEC temperature range spanning from -50 to +150°C. The analog interface of the controller extends remote control capabilities, and the preset display functionality empowers users to fine-tune the operating setpoint before engaging the output.
