RHM5K-CH TEC Driver

The PTC-CH Series Chassis Mount Temperature Controllers deliver the precision performance and long-term reliability you expect from a Wavelength Electronics temperature controller. PTC-CH Series controllers are found in such diverse applications as particle and droplet measurement, manufacturing machine vision systems, biomolecular interaction analysis, and more.The PTC-CH controllers operate from a single power supply between 4.5 V and 30 V, and a selection of models allows you to optimize the current output level for your application. The linear bipolar controller drives a Peltier thermoelectric cooler or a resistive heater, and the chassis-mount package integrates easily into OEM applications. PTC-CH controllers interface with a variety of temperature sensors, and the bias current is adjustable in order to maximize controller sensitivity and stability for your application.The compact chassis-mount design simplifies heatsinking and requires minimal space. PTC-CH controllers are quick to configure for your prototype project, and there are no surprises when it's time to integrate the controller into the final design.Practical Features For Real-World Conditions Built-in features make your product more robust to real-world operating conditions and minimize your electronics overhead: If the optional remote temperature setpoint signal is lost, the controller defaults to a standard "safe" temperature setpoint (25ºC when a 10 k© thermistor is used). The safe temperature can be changed at the factory; call for details. An on-board trimpot is used to set the output current limit to prevent over-driving the TEC, and helps protect your load from thermal runaway situations. Proportional gain is easily adjusted with an on-board trimpot. Low temperature coefficient design remains stable across a wide range of ambient conditions. When used with Wavelength's laser drivers, such as the PLD Series, these temperature controllers provide stable and reliable performance that sets your system apart from your competitors' and keeps your customers satisfied.

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!
