The Model 350B Thermoelectric Cooler (TEC) Controller offer a combination of features, performance, and value that is unmatched by other TEC controllers.
Three operating modes are user selectable: constant R (thermistor), constant T (thermistors and IC sensors), or constant ITE (current to TE cooler), while delivering output power of 55 W.
Quiet, safe output current results from P-I-D control loop 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.
When it comes to selecting a laser diode mount and driver to go along with your new temperature controller Newport does all the work for you. Our newly introduced laser diode control kit (LDKIT series) bundles the diode driver, temperature controller, mount, cables and thermal paste compound all at a great price.
LDKIT-6A-55W includes the 560B laser diode driver, 350B temperature controller, 764H-061 mount, cables and thermal paste.
Additional Benefits
- Preset display lets you adjust operating setpoint before switching the output on
- Low noise, bipolar current output - <30µA
- Units are displayed in °C when using IC sensors and optionally with thermistors
