5R6-900 Benchtop Temperature Controller

Output Current TEC ±2.5, ±5, ±10 A; Chassis Mount; Supply Voltage 5-15 VDC; USB Communication Interface Optional; Temperature Stability 0.002-0.005°C MPT Series TEC temperature controllers are not recommended for new designs and have been replaced with the PTCxK-CH Series TEC temperature controllers. Wavelength Electronics’ MPT Series of chassis-mount TEC temperature controllers drives up to 2.5 A (MPT2500), 5 A (MPT5000) or 10 A (MPT10000) for either thermoelectrics (TEC, bipolar) or resistive heaters (unipolar). The robust MPT series’ circuitry achieves temperature stabilities of 0.002°C to 0.005°C. These temperature controllers interface with virtually any type of temperature sensor. An onboard sensor bias current source can drive thermistors, RTDs, or the LM335 semiconductor temperature sensor IC. For current sensors like the AD590, simply bias it and drive it into the sensor input. A trimpot adjusts the Proportional Gain (P). A fixed Integrator Time Constant (I) capacitor can be custom fit to your application to optimize temperature overshoot and stability. Another trimpot adjusts the setpoint temperature. You can use a remote signal (D-to-A, or remote trimpot, for example) with the external analog input to control the operating temperature. Up to 28 V can be delivered to the load with 30 V input. Heatsinking then becomes critical and a Safe Operating Area (SOA) tool is available to make sure you don’t exceed the maximum internal power dissipation of the package. Monitor pins bring out both setpoint and actual temperature signals. Current limit is set via a single-turn trimpot under the controller’s cover. Accessories for the MPT Series TEC temperature controllers include WCB101 cabling to the male DSub15 connector as well as the MULTI-HTSK heatsink for evaluating the unit on a benchtop and an external USBKIT USB interface. Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. The standard product can be easily modified to meet your application requirements. Get in touch with the AMS Technologies TEC temperature controller experts to discuss your customized solution!

The LFI3751 with Autotune PID is a high performance temperature control instrument. Drive up to ±5 A to either thermoelectrics (TECs) or resistive heaters (RH) with up to 8 V compliance. This instrument operates from AC (115 / 230, 50 or 60Hz). Expect stability as good as 0.001°C with thermistors. Even across ambient, this PID controller maintains precision temperature. From the front panel, adjust temperature limits, current limits, setpoint, PID control values, sensor calibration data, and enable or disable output current. The 4-digit display shows actual or setpoint temperature or resistance, output current and voltage.This instrument offers unique features. Autotune PID is a sophisticated algorithm for optimizing the PID control parameters to your load. With the touch of a button, the LFI3751 automatically optimizes control settings for most thermal loads, reducing overshoot or improving temperature stability. Autoranging sensor bias currents keep your sensor voltage in the optimal range for maximum signal to noise ratio. It comes with Addressable RS232 and USB control is available with an adapter cable: WCB404. Free Labview drivers simplify computer control. Benchlink software simulates the front panel control from your PC. (NOTE: The Benchlink Installer is not compatible with 64-bit operating systems. A work-around for Benchlink install is available. Contact Tech Support for details if your application uses the Windows 64-bit OS and Benchlink front panel emulation control.)Sensor calibration is easy with a reference right on the front panel. For example, to calibrate your thermistor, simply enter three data points from the Resistance vs. Temperature curve. The LFI3751 calculates the Steinhart-Hart coeffecients and displays either actual temperature or sensor resistance. Also view Thermoelectric current and voltage and limit current settings. The LFI3751 Digital option provides better set point resolution and stability with low resolution sensors such as RTDs. This option also offers improved overshoot suppression, 50% faster settling times, and faster calibration. An Analog control model is available: LFI3751 Analog Key Features < 0.002 °C temperature stability even at ambient Controls temperature with thermistors, RTDs, LM335, or AD590
