350 In Stock

The 350 by Newport is a Thermoelectric Temperature Controller offers a comprehensive solution for optimizing the utilization of thermoelectric (TE) modules in the context of heating or cooling applications involving IR detectors, laser diodes, and various semiconductor devices. This controller boasts a diverse spectrum of power outputs and maintains superior temperature stability. Operating across three distinctive modes – constant ITE, constant T, and constant R – the controller facilitates the delivery of a bipolar and low-noise current output. It features an adjustable ITE current limit setting that serves the dual purpose of user customization and safeguarding TE modules against potential damage stemming from excessive drive currents, irrespective of the chosen mode of operation. The 350 controller demonstrates compatibility with an array of temperature sensors, including thermistors, AD590, and LM335 series IC temperature sensors.

The 350 controller has been crafted to interface with a thermistor as its primary temperature sensing component. The temperature is accurately represented as a resistance value (kΩ), which corresponds to the thermistor's temperature. Precise current sources of 10 µA and 100 µA are harnessed to generate a voltage across the thermistor, the resulting value of which is then conveniently displayed on the front interface. The 350 controller is adept at incorporating two IC temperature sensors known for their user-friendly nature and direct temperature readings in degrees Celsius. Fundamentally, this controller functions by orchestrating a feedback loop mechanism that adeptly manages the heating and cooling processes. It leverages this mechanism to regulate both the rate and extent of temperature adjustment. An integral aspect of the controller's performance pertains to the physical arrangement of constituent components, including the device itself, the heatsink, the thermistor, and the TE module subject to temperature modulation. This arrangement plays a pivotal role in determining the rate of heat dissipation, to which the controller's circuitry responds, as well as influencing the overall thermal load implications.
