Product Overview:

216 Watt, High Voltage TEC Controller Overview

The TEC-305 is a high stability laser diode and non-linear crystal TEC controller which delivers up to 216 watts of output power to a Peltier cooler: the bipolar TEC current range is ± 12 Amps and the voltage range is ± 20.00 volts. The high voltage range allows the user to control multiple Peltier coolers in series. Designed to protect your laser diode from over-temperature damage, these TEC control modules provide precise temperature control of your laser diode or non-linear crystal based on fast closed-loop feedback from negative thermal coefficient thermistors (ie 10K thermistors) as well as as IC sensors such as PT100 and PT1000 sensors. The full PID control loop keeps your laser diode at your desired temperature set-point with milli-degree stability.

User Control Interface

These modules are controlled from an RS-232 interface (standard) or a USB interface. They are offered LabVIEW drivers as well as a terminal software control suite to make integration into your lab test set-up or product integration simple and fast. The GUI shows all of the control functions, including the current and voltage levels to the TEC controller output and the ability to adjust the PID control loop variables. The user can adjust each of the PID variables to optimize the temperature settling speed or us the default factory settings to get up and running quickly.

Controller Features

The full PID loop provides millidegree temperature stability, and can quickly stabilize high heat loads to the temperature set-point to reduce the risk of damage to your laser.

User adjustable upper and lower temperature limits can be programmed to protect the laser diode and the Peltier device. Additionally, TEC output current limits are user-configured to protect the Peltier device from over-drive damage.

External Fan Control for Additional Heat Control Capability

The controller includes an output to control an auxiliary device, such as a heat-sink fan, or an external electro-optical device in laboratory or manufacturing testing applications. The auxiliary control is capable of 24 V and 500 mA output.
