TEC Temperature Controllers

Output Current TEC ±1.5, ±3, ±4 A; PCB Mount; Supply Voltage 5-12 VDC; Temperature Stability 0.0009°C With its advanced and reliable circuitry, Wavelength Electronics’ HTC series of component type TEC temperature controllers achieves 0.0009°C temperature stability. Its low-profile package is ideal for designs with space constraints and can be mounted in a number of different ways. The HTC can be electrically connected to a PCB or by using a SIP connector and cable. The heatsink can be bolted directly to the HTC series device, or the device can be bolted directly to the equipment chassis to maximize space efficiency. The ultra-stable linear, PI control loop offers maximum stability, while the bipolar current source has been designed for higher efficiency. The HTC series drives up to ±4.0 A for either thermoelectrics (bipolar) or resistive heaters (unipolar). Three maximum output current ranges are available: ±1.5, ±3 and ±4 A. While regular drivers for 1.5 and 3 A are designed for 0.031 inch (0.79 mm) thick printed circuit boards (PCBs), each of the models (including drivers for 4 A) is also available as a “HTCxxoo-62” variant, suitable for mounting on 0.062 inch (1.57 mm) thick PCBs. The HTC Series TEC temperature controllers are easily configured for any design. Virtually any type of temperature sensor can be used with the HTC, and a built-in sensor bias current source simplifies use with resistive temperature sensors. The independently adjustable proportional gain (P) and integrator time constant (I) can be modified to optimize temperature overshoot and stability. Other features offer added flexibility. A single resistor sets the maximum output current to load. Add a diode to operate resistive heaters with a unipolar output current. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage. Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies TEC Temperature Controllers experts to discuss your customized solution!

Output Current TEC ±5 A; Benchtop or Rack Mount; Supply Voltage 115/230 VAC; RS232, USB Communication Interface; Temperature Stability 0.001 °C Wavelength Electronics’ LFI3751 series are high-performance instrument type temperature controllers with Autotune PID. 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 VAC, 50 or 60 Hz). 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. An external analog setpoint input is via BNC on the rear panel (LFI3751 ANALOG version only). The 4-digit display shows actual or setpoint temperature or resistance, output current and voltage. The LFI3751 series 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 optimises 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. Free LabVIEW drivers simplify computer control. Benchlink software simulates the front panel control from your PC. 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 coefficients and displays either actual temperature or sensor resistance. Also, view thermoelectric current and voltage and limit current settings. A digital PID option is available in the LFI3751 DIGITAL temperature controller. This option provides better set point resolution and stability with low-resolution sensors such as RTDs as well as improved overshoot suppression, 50% faster settling times and faster calibration. When controlling laser diode temperature, the LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the LFI3751 series and the laser. Wavelength also offers the TC LAB series of temperature control instruments with higher current and voltage capacity, a touchscreen interface, IntelliTune PID control optimization, and better stability. Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies temperature controller experts to discuss your customized solution!

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.
