Catalog excerpts

300B Series Temperature Controllers The New 300B Series Temperature Controllers offer a combination of features, performance, and value that is unmatched by other temperature controllers. Three operating modes are user selectable: constant R (thermistor), constant T (IC sensors), or constant ITE (TE cooler), while delivering output power of 17.5 W or 55 W. Quiet, safe output current results from P-I-D control circuitry with complete flexibility for adjustment through the Newport LDD/TEC Application software (included) or user developed programs. The PID control algorithm achieves optimal stability and settling performance along with an ITE current limit setting protects TE coolers from damage, regardless of operating mode. Additional Benefits • Preset display lets you adjust operating setpoint before switching the output on • Low noise, bipolar current output - <30ìA • Wide TEC temperature range from - 50 to +150°C • Units are displayed in °C when using IC sensors and optionally with thermistors • USB 2.0 interface for remote control Call Newport’s Application Sales Engineers to help you determine which Temperature Controller best meets your LD Cooling requirements.
